• Inspect Electrical Connections: A simple check of all electrical connections can often solve electrical issues like non-functioning lights or gauges.
  
• Perform Diagnostic Tests: Some models come equipped with diagnostic tools that can help identify underlying problems. Use the onboard diagnostic system to check for any error codes.
  

Planning a Burn Site Near Urban or Commercial Areas
Burning tree piles near businesses or banks requires careful planning. Wind direction, visibility, and local ordinances must be considered before ignition. A burn permit is often mandatory, especially in urban zones. Authorities may impose restrictions on burn hours, supervision, and allowable materials. In one case, a landowner near a commercial district consulted the town clerk and fire dispatcher before burning. This proactive approach prevented fines and ensured emergency services were informed, avoiding unnecessary fire department responses.
Choosing the Right Ignition Method
The most effective and environmentally responsible ignition method involves using dry brush, newspaper, and diesel-soaked straw or hay. This combination creates sustained heat and minimizes toxic emissions. A common ratio used by bushfire crews is 1 part gasoline to 4 parts diesel, applied with a drip torch. This mixture ignites quickly and burns hot enough to consume wet wood. Avoid using rubber tires or treated timber, as they release hazardous pollutants including dioxins, benzene, and heavy metals.
Building and Managing the Fire
To ensure efficient combustion:

• Start the fire on the windward side so flames are pushed into the pile
  
• Use small twigs and leaves as kindling to generate initial heat
  
• Avoid disturbing the coal bed once established—push material onto hot coals rather than stirring
  
• Keep dead dry tops or branches nearby to restoke the fire if needed
  
• Monitor the fire continuously and have equipment ready to control flare-ups
  

• Chipping and mulching: Converts debris into usable ground cover
  
• Burn boxes: Enclosed combustion chambers with forced air systems
  
• Trench burning: Uses dug pits with blower tubes to feed oxygen
  
• Hauling to biomass facilities: Where material is converted to energy
  

When it comes to maintaining and repairing heavy equipment, one of the most challenging tasks can be removing bucket pins, especially on older models such as the John Deere Hitachi excavators. These machines, often working in harsh conditions for many years, can have bucket pins that become stuck due to rust, dirt, and wear. Proper pin removal is essential for maintenance or for replacing parts such as the bucket or attachment. This article discusses the steps, tools, and techniques involved in removing stuck or difficult-to-remove bucket pins on older John Deere Hitachi models.
Understanding the Problem: Why Bucket Pins Get Stuck
Bucket pins are essential components that allow the bucket to rotate or move independently of the excavator’s arm. They are critical for attachment, pivoting, and securing the bucket. Over time, exposure to dirt, water, and extreme wear can cause these pins to seize, making it difficult to remove them without proper techniques. Here are some of the reasons why bucket pins become stuck:

• Rust and Corrosion: Continuous exposure to weather, water, and dirt can cause rust to form around the pin and its housing. Corrosion can cause the pin to seize in place, making it tough to remove.
  
• Dirt and Debris: After extensive use, dirt, mud, and other debris can build up around the pin, increasing friction and making it difficult to slide the pin out.
  
• Wear and Tear: As the equipment ages, the pin can wear down unevenly, leading to tight spots in the pin and sleeve, causing difficulty during removal.
  

1. Hydraulic Puller: A hydraulic puller is one of the best tools for pin removal, especially when the pin is severely stuck. These tools apply pressure to remove stubborn pins without damaging the surrounding parts.
   
2. Penetrating Oil or Lubricant: Products like WD-40 or PB Blaster can break down the rust and corrosion around the pin, making removal easier. Applying a liberal amount of penetrating oil to the pin and letting it sit for an extended period can help loosen the bond.
   
3. Impact Wrench: An impact wrench can provide additional force to break the pin loose, especially when the pin is rusted and tight.
   
4. Welding Equipment: In some cases, heat can be used to loosen the pin. This is usually done by heating the pin or housing with a torch, then using a cooler environment (such as a cold water application) to contract the parts and loosen the pin.
   
5. Sledgehammer or Mallet: While more forceful methods should be used sparingly, a sledgehammer can sometimes be used to tap the pin out, especially when combined with penetrating oil or heat.
   

• Secure the Excavator: Park the excavator on a flat, stable surface and ensure the bucket is fully lowered to relieve any stress on the pin.
  
• Clean the Area: Clean the area around the pin using a wire brush or compressed air. Remove any dirt or debris that could get in the way during the process.
  

• Spray Generously: Apply a generous amount of penetrating oil (like WD-40 or PB Blaster) to the pin and surrounding area. Focus on the area where the pin meets the bucket and the arm.
  
• Let it Soak: Allow the penetrating oil to soak for at least 15-30 minutes. For particularly stubborn pins, it’s worth leaving the oil to sit overnight.
  

• Heat the Pin: Use a torch to heat the pin or the housing around the pin. Aim to heat the pin evenly for a few minutes. This can expand the metal slightly, breaking the rust or corrosion.
  
• Apply Cold: After heating, rapidly cool the pin using cold water or compressed air. The contraction of the metal can help loosen the pin from the housing.
  

• Use a Hydraulic Puller: Attach the hydraulic puller to the pin and apply pressure slowly. Hydraulic pullers provide even force, reducing the risk of damage.
  
• Tap with a Mallet: If the pin has loosened up but won’t come out, use a sledgehammer or mallet to tap the pin from the opposite end. Be careful not to strike too hard, as this could damage the pin or surrounding components.
  
• Impact Wrench: If you still have trouble, use an impact wrench to provide additional force. This tool is useful when the pin has become lodged in place and requires more than manual effort to dislodge.
  

• Check the Pin and Housing: If the pin was severely rusted or corroded, check both the pin and the housing for any damage. You may need to replace both to avoid future issues.
  
• Replace Worn Parts: If the bucket or arm’s pivot points are excessively worn, replace the components as needed to ensure smooth operation going forward.
  

• Lubricate Regularly: Apply a lubricant to the pins and surrounding areas regularly, especially after cleaning or working in harsh conditions. Lubrication helps reduce friction and prevent corrosion.
  
• Use High-Quality Pins and Bushings: When replacing pins, use high-quality, corrosion-resistant materials to ensure longer-lasting parts.
  
• Store the Machine Properly: Keep your excavator in a sheltered area or use covers to protect it from extreme weather, which can accelerate rusting and corrosion.
  

Starting Out with a Skid Loader
In late 2013, a new operator in Missouri purchased a skid loader primarily for personal use—handling firewood, moving car parts, maintaining property, and building a garage. The machine was paid for in cash, and the owner began exploring small paid jobs to offset maintenance costs. Equipped with a smooth bucket, a tooth bucket, and an auger, he was also fabricating a root bucket and considering future attachments like pallet forks, a grapple, or a 4-in-1 bucket.
This setup reflects a common entry point into compact equipment contracting: owning a versatile machine and gradually expanding capabilities based on job demand and budget.
First Paid Job and Pricing Challenges
The first paid job involved spreading six 20-ton loads of material—three of 2" clean rock and three of fill/washout—to build a level pad for RV parking and a future pole barn. The customer requested a 2+ foot elevation gain at one end. The operator quoted $75/hour and estimated two hours, but the customer countered with a flat $200, citing rental costs. Despite feeling lowballed, the operator accepted the job to gain experience and build a local reputation.
This pricing scenario is common in entry-level contracting. Homeowners often compare quotes to rental rates, overlooking transport, fuel, wear, and operator skill. Accepting underpriced jobs can help build a portfolio, but it risks setting unsustainable expectations.
On-Site Learning and Technique Adjustment
Initially, the operator rushed the job, driving aggressively over piles and working at full throttle. After realizing the risk of tipping and inefficiency, he slowed down, adopted a half-throttle approach, and began moving material one bucket at a time while smoothing on return passes. This shift improved control and productivity.
He also paused periodically to check grade and ensure the pad met specifications. The job was completed in 2.5 hours, and the customer was satisfied—offering referrals to others with similar needs.
Equipment Care and Bucket Maintenance
The operator used an 84" smooth bucket with a welded wear plate featuring bolt holes for optional teeth. After the job, he considered adding a bolt-on cutting edge to protect the bucket’s face during backdragging. This is a smart move: bolt-on edges are sacrificial and can be replaced without damaging the bucket shell.
He also owned a 72" tooth bucket and was evaluating larger options. A removable tooth bar could offer flexibility for switching between digging and finish grading.
Business Setup and Terminology
For branding, the operator debated using “excavating” on business cards. While accurate for digging and grading, “land services” or “site prep” may better reflect the scope of skid loader work. He also questioned whether to use “skid loader,” “skid steer,” or “Bobcat.” While “Bobcat” is a brand, it’s widely recognized and often used generically. “Skid steer” is the most technically correct and accepted term in professional circles.
Minimum Charges and Service Expansion
He proposed a $200 minimum for jobs within 30 minutes and $400 for longer travel. This is reasonable if it covers fuel, transport, and setup time. For auger work, charging per hole is fair, especially if the auger was a significant investment. Once the cost is recovered, offering it as a bundled service can attract more jobs.
He was also building an F450 dump truck to haul material. For delivery pricing, a flat fee covering fuel, insurance, and time is often better than per-mile charges, which can confuse customers.
Conclusion
This first job offered valuable lessons in pricing, technique, customer interaction, and equipment care. While underpriced, it led to referrals and practical experience. For new operators, balancing learning with profitability is key. Clear communication, controlled operation, and thoughtful upgrades can turn a side machine into a reliable income source.

In the world of heavy equipment, cold weather can present a range of challenges, especially when it comes to older machinery. One common issue faced by operators is the slow operation of loaders as temperatures drop. When loaders that once operated smoothly begin to slow down or struggle in colder weather, it can lead to frustrating delays on the job site. Understanding the potential causes of this issue and how to address them is crucial to keeping your loader in optimal working condition.
Understanding the Impact of Cold Weather on Loaders
Cold temperatures affect various aspects of heavy machinery, especially older models. As the temperature decreases, it causes the fluids within the equipment to thicken, which can lead to a variety of operational issues. These issues might include sluggish hydraulics, slow engine turnover, and even increased fuel consumption.
Older loaders, particularly those with more wear and tear, tend to be more vulnerable to these problems, as the parts may not function as smoothly as when the equipment was new. Let’s break down the key areas that are impacted by cold weather and cause slow performance:
1. Thickened Hydraulic Fluids
Hydraulic systems in loaders rely on fluid to transmit power efficiently throughout the machine. As temperatures drop, hydraulic fluid becomes thicker and more viscous. This increase in fluid viscosity can result in slower response times in the loader’s hydraulic system. It may take longer for the loader’s arms and bucket to raise and lower, and the overall responsiveness of the machine can feel sluggish.

• Solution: Using a low-viscosity hydraulic fluid designed for cold temperatures can help prevent this issue. Additionally, regular fluid changes and maintaining the correct fluid levels can ensure smoother operation during colder months. Consider installing a hydraulic fluid heater if your equipment operates in extreme conditions regularly.
  

• Solution: Consider switching to a multi-viscosity engine oil that is rated for colder temperatures. Diesel engines may benefit from a fuel additive designed to prevent fuel gelling. It's also important to keep your fuel tank full during winter months, as condensation inside the tank can freeze and cause fuel line blockages.
  

• Solution: Before the colder months hit, check the condition of your battery. Clean the terminals, check for corrosion, and ensure the battery is fully charged. If your loader has an older battery, it might be wise to replace it with a new one designed for cold weather operation. Keeping the battery warm in cold temperatures with insulated covers can also help prolong its life.
  

• Solution: Regularly inspect the loader for worn or cracked seals, hoses, and joints. If parts are freezing up, applying a lubricant or anti-freeze solution to the moving parts may help prevent them from becoming stiff or stuck. Ensure that the loader is parked in a warm, dry area during the colder months to prevent freezing.
  

• Solution: Using winter-grade diesel fuel or adding a fuel conditioner can help mitigate this issue. Regularly maintaining the fuel system and replacing fuel filters will ensure the engine runs smoothly and efficiently. Additionally, parking the machine in a warm area or using engine block heaters can reduce the initial load on the engine.
  

• Preseason Maintenance: Before the weather turns cold, conduct a thorough maintenance check on the loader. This should include changing the hydraulic fluid, engine oil, and fuel filters. Check the battery and ensure it’s fully charged and in good condition.
  
• Invest in Warm-up Equipment: Many modern loaders come with optional warm-up equipment such as block heaters or hydraulic fluid heaters. If your loader doesn’t have these features, consider investing in aftermarket solutions. These heaters can warm the engine and hydraulic system before starting, making the machine more efficient and reducing the strain on parts.
  
• Use Heated Storage: If possible, store your loader in a heated garage or shed during the winter months. Keeping the machine warm will reduce the chances of freezing components and make it easier to start.
  
• Regular Monitoring: During winter, regularly monitor your loader’s performance, including checking fluid levels, ensuring there are no frozen components, and observing any changes in engine behavior. Address issues early to prevent breakdowns.
  

Understanding Hard vs Soft Parts in Equipment Maintenance
In the world of heavy equipment, parts are often categorized into two broad groups: hard parts and soft parts. Hard parts include structural and mechanical components such as pins, bushings, seal kits, clutch packs, and hydraulic cylinders. These are typically subject to wear over long intervals or during major repairs. Soft parts, on the other hand, refer to filters, belts, hoses, fluids, and fittings—items replaced during routine maintenance.
This distinction matters because hard parts often require precise tolerances, material strength, and compatibility with mating components. Choosing between OEM (Original Equipment Manufacturer) and aftermarket sources for these parts can significantly affect machine longevity and performance.
Why OEM Parts Still Dominate High-Production Machines
For machines operating in high-production environments—such as quarries, road building, or municipal fleets—OEM parts are preferred due to their proven durability and engineering consistency. OEM components are manufactured to exact specifications, often with proprietary metallurgy and surface treatments. For example, Rockwell hardness ratings on OEM pins and bushings are tightly controlled to prevent premature wear or deformation.
Operators report that while OEM parts may cost 30–50% more, they often last twice as long. In one industrial maintenance case, a purchasing department substituted a cheaper aftermarket bearing, only to have it fail in half the expected cycle time, leading to costly downtime and emergency repairs.
When Aftermarket Parts Make Sense
For part-time machines or those used in light-duty applications—such as land clearing, farm work, or seasonal grading—aftermarket parts can offer excellent value. Many reputable suppliers produce components that meet or exceed OEM specifications, especially for common wear items like:

• Quick attach pins and bushings
  
• Hydraulic seal kits
  
• Loader arm pivot pins
  
• Cylinder repack kits
  

• Consumables: Tires, cutting edges, filters—often purchased in bulk from jobbers or fleet suppliers
  
• Repair parts: Engines, transmissions, pumps—typically sourced from OEM or certified rebuilders
  
• Implement joints and wear parts: Pins, bushings, seals—evaluated case-by-case based on usage and budget
  

• Request material specs, including hardness and coating type
  
• Compare dimensions with OEM drawings or removed parts
  
• Use trusted suppliers with industry certifications or positive field reviews
  
• Monitor wear closely after installation, especially in critical joints
  
• Avoid mixing OEM and aftermarket components in the same assembly unless compatibility is confirmed

John Deere 310E Backhoe Loader Overview
The John Deere 310E was introduced in the early 1990s as part of Deere’s evolution of the 310 series, which began in the 1970s. The 310E featured a turbocharged four-cylinder diesel engine producing around 70 horsepower, a torque converter transmission, and hydraulic wet clutch packs for directional control. With an operating weight of approximately 14,000 lbs, it was widely used in utility work, trenching, and road maintenance. Deere’s modular design allowed for relatively straightforward service access, making it a favorite among owner-operators and municipal fleets.
Symptoms Leading to Transmission Removal
After a year of intermittent use following a charge pump replacement and control valve cleaning, the transmission began slipping again. Inspection revealed clutch friction material clogging the pickup screen, indicating internal wear. The decision was made to pull the transmission and inspect the clutch packs, seals, and bearings.
Preparation and Lifting Strategy
To begin the removal:

• The machine was raised on jackstands to 35 inches at the battery compartment, exceeding the manual’s minimum clearance of 34 inches.
  
• Hydraulic tank and transmission fluid were drained.
  
• Hydraulic pump, lines, dipstick tube, driveshafts, gear shifter, and electrical connections were removed.
  
• The torque converter bolts were accessed by locking the flywheel with a large screwdriver through the starter hole.
  

• The MFWD (mechanical front wheel drive) driveshaft seal and dust cover remained on the shaft during case separation.
  
• Deere’s seal driver tool (JDG1057) is designed to install the seal and shield to precise depth, though it was unavailable. A custom driver was fabricated.
  
• The clutch packs were inspected for wear, and all o-rings and seals were scheduled for replacement.
  

• Replace all seals, o-rings, and sealing rings, regardless of visible wear.
  
• Use OEM clutch frictions and steels if possible. Aftermarket parts may vary in quality and longevity.
  
• Inspect bearings and gears carefully. If they show no wear, reuse is acceptable.
  
• Replace the fuel return line if damaged during removal. The correct size is typically 5/16 inch.
