Outdoor work, especially when involving heavy equipment or machinery, can offer a unique and rewarding experience. Whether it's construction, forestry, or agricultural tasks, spending hours outdoors exposes workers to a variety of risks and rewards. However, as enjoyable as working in the sun can be, there are critical safety concerns that need to be addressed to ensure the health and well-being of those involved.
The Joy and Challenges of Working Outdoors
For many individuals, working outdoors provides a break from the conventional office or indoor settings. The fresh air, the connection with nature, and the satisfaction of completing a task using machinery are among the many benefits. However, it also comes with its challenges. Working outdoors exposes individuals to the elements, with the sun being both a companion and a potential danger. Extended exposure to the sun, particularly without proper protection, can lead to harmful effects such as dehydration, heat stroke, and skin damage.
The Risks of Sun Exposure
Sunburn is the most immediate concern for individuals who work in the sun for extended periods. The ultraviolet (UV) rays from the sun can cause significant damage to the skin, increasing the risk of skin cancer in the long term. Overexposure to UV radiation can lead to sunburn, which causes pain, redness, and blistering of the skin. Repeated instances of sunburn can contribute to the development of skin cancer later in life.
Another risk is heatstroke, a condition that occurs when the body is unable to regulate its internal temperature. Heatstroke can be life-threatening if not treated promptly. Workers who operate heavy machinery in hot conditions are especially vulnerable to this condition, which can occur suddenly and without warning. The symptoms include confusion, dizziness, rapid heartbeat, and even loss of consciousness.
Sun Safety: How to Protect Yourself
To prevent sun-related injuries while working outdoors, it is crucial to take certain precautions. The first step is to wear appropriate clothing. Lightweight, light-colored fabrics are ideal as they allow air circulation and reflect the sun's rays. A wide-brimmed hat provides shade and protects the face, neck, and ears. Additionally, wearing UV-protective gloves, sunglasses, and sunscreen with a high SPF rating can help block out harmful rays.
For individuals working with heavy machinery, it’s also important to stay hydrated. Dehydration can worsen the effects of heat and reduce cognitive function, making it harder to operate machinery safely. Drinking water regularly throughout the day and taking scheduled breaks in shaded or cooler areas will help maintain hydration and regulate body temperature.
Workplace Equipment and Sun Safety Integration
Many workplaces that require extended outdoor labor are integrating sun safety measures into their daily routines. Some companies are providing workers with more protective gear, such as full-body suits with UV protection and cooling vests. Others have installed shade structures and misting systems in areas where workers take breaks.
As an additional measure, many organizations now emphasize the importance of work schedules that avoid the sun's peak intensity, typically between 10 AM and 4 PM. By scheduling more strenuous tasks in the early morning or later in the afternoon, companies can reduce the risks associated with direct sun exposure.
A Personal Story: Working in the Sun
One individual recalls their experience working in the sun, operating a bulldozer for hours at a time. They initially enjoyed the freedom and the outdoor environment, but soon learned the importance of staying protected. One particularly hot summer day, they failed to take enough breaks, and the heat caught up with them. They felt dizzy and disoriented, realizing that they had neglected hydration and sunscreen. A fellow worker noticed the signs of heat exhaustion and took them to a shaded area to recover.
This experience prompted the worker to change their habits, ensuring that they always wore sunscreen, drank water regularly, and sought shade whenever possible. Their story serves as a reminder of the importance of listening to your body and prioritizing safety, especially in harsh environments like construction sites or farms.
Conclusion: Enjoying the Outdoors Safely
While outdoor work can be highly fulfilling, it is essential to approach it with respect for the risks involved. The sun may be a constant companion for those working outdoors, but taking the necessary precautions can help prevent long-term health consequences. By wearing protective gear, staying hydrated, and managing work schedules to avoid excessive sun exposure, workers can continue to enjoy the outdoors safely while minimizing health risks.

Introduction to the MF50H Front Hub Assembly
The Massey Ferguson MF50H 4WD backhoe loader, particularly the 1989 model, features a robust front axle system—often a Carraro design—built to handle demanding terrain and load conditions. However, decades of service without disassembly can lead to seized components, especially in the planetary hub assembly. When a front wheel locks up, the root cause is often internal bearing failure, compounded by corrosion and gear damage.
Key Terminology - Planetary Hub: A gear reduction system at the wheel end that multiplies torque and distributes load.
- Sun Gear: The central gear in a planetary system, around which planet gears rotate.
- Carrier: The frame holding the planetary gears, often splined to the axle shaft.
- Allen Head Retaining Bolts: Hex-socket bolts used to secure hub covers and internal components.
- Loctite: A thread-locking compound that can make bolt removal difficult after long-term curing.
Initial Symptoms and Disassembly Challenges
The wheel seizure was traced to a front hub that had likely never been opened since factory assembly. The technician encountered three 5mm Allen head bolts securing the faceplate, which resisted removal despite heat and penetrating oil. This is common in aged assemblies where Loctite and corrosion have hardened over time.
Recommended removal techniques included:- Center Punch and Hammer Shock
Applying impact to break thread bond, though risky for cast components.
- Drilling Bolt Heads
A safer alternative to avoid damaging the cap, especially when using left-hand drill bits.
- Impact Screwdriver with Heat
Loosens Loctite and breaks corrosion bonds without excessive force.
Planetary Hub Access and Component Identification
Once the faceplate was removed, the technician discovered catastrophic bearing failure inside the planetary hub. To access the planetary gears and half-shaft bearings, the following steps were advised:- Remove Tire and Rim
Clean around wheel studs and flange to expose recessed Allen bolts and oversized wheel studs.
- Double-Nut and Extract Studs
Two wheel studs with larger shoulders must be backed out alongside the Allen bolts.
- Slide Out Planetary Assembly
The planetary gear set can be removed by sliding it off the remaining studs, though seized gears may require force.
- Use Wedge and Hammer
Drive the cover off the hub at multiple points if the sun gear and planetary gears are fused by damage.
Root Cause: Bearing Failure and Gear Damage
Upon inspection, the hub revealed severe bearing degradation, likely due to:- Lack of Lubrication
Old grease or oil may have broken down, allowing metal-on-metal contact.
- Water Ingress
Seals may have failed, introducing moisture and accelerating corrosion.
- Gear Fusion
Damaged bearings allowed misalignment, causing gears to bind and seize.
Field Anecdote: Carraro Axle Rebuild
A technician familiar with Carraro axles noted that planetary hubs often seize when the sun gear and planet gears “make friends”—a euphemism for destructive gear contact. In one case, a loader used in coastal conditions suffered similar failure due to saltwater exposure. The planetary assembly had to be removed with a hydraulic puller and rebuilt using parts sourced from Joseph Industries, a known supplier of Carraro components.
Parts Sourcing and Technical Support- Joseph Industries
Offers Carraro axle parts and technical guidance via phone support.
- AGCO Parts Books
Hosts diagrams for MF50H and similar models, though access may require dealer credentials.
- Custom Fabrication
In cases where parts are obsolete, some technicians machine replacement spacers or bushings locally.
Recommended Repair Steps- Remove planetary assembly using stud extraction and impact tools
- Inspect all gears for wear, pitting, or fusion
- Replace failed bearings with OEM or high-grade equivalents
- Clean and re-lubricate all components before reassembly
- Use anti-seize or fresh Loctite on bolts as appropriate
- Reinstall with torque specs and alignment checks
Preventive Maintenance Tips- Inspect hub seals annually for leaks or wear
- Change hub oil or grease at regular intervals
- Avoid pressure washing near seals and bearings
- Monitor wheel temperature during operation for early signs of friction
- Keep a log of service intervals and component replacements
Conclusion
A seized front wheel on the MF50H 4WD is more than a nuisance—it’s a mechanical failure rooted in time, wear, and overlooked maintenance. With careful disassembly, targeted diagnostics, and quality parts, even a decades-old planetary hub can be restored to full function. This case underscores the importance of understanding gear systems and the value of patience when working with legacy iron.

The New Holland LX885 skid steer loader is a versatile and powerful machine widely used in construction, landscaping, and agricultural tasks. However, like any piece of heavy equipment, it may face issues, such as difficulties in starting. This article provides a detailed guide on diagnosing and resolving starting issues in the LX885, addressing common causes, step-by-step troubleshooting procedures, and maintenance tips to prevent future problems.
Understanding the Common Starting Issues
When a New Holland LX885 won’t start, there are several potential causes that need to be checked systematically. These can range from electrical issues to fuel system problems. Common symptoms of starting problems include a no-crank situation (when the engine doesn’t even attempt to turn over) or an engine that turns over but fails to start.
Key Indicators to Look Out For - No crank: The engine doesn’t turn over at all.
- Slow crank: The engine turns over slowly, and the starter struggles to engage.
- Cranks but won’t start: The starter motor runs, but the engine does not catch or fire up.
- Intermittent starting: The machine starts sometimes, but other times, it doesn’t.
Step 1: Checking the Battery and Electrical Connections
One of the most common causes for starting issues in the LX885 is an issue with the battery or electrical system. Here’s how to troubleshoot:
Battery Health
Start by checking the battery voltage. A low battery or corroded battery terminals can prevent the LX885 from starting properly. The battery voltage should typically be around 12.6 volts when fully charged. If the battery voltage is low, try jump-starting the skid steer to see if it starts. If the machine starts with a jump, it’s a clear indicator that the battery might need replacement.
Corrosion or Loose Connections
Examine the battery terminals for any corrosion or loose connections. Corrosion can cause a poor electrical connection, leading to weak or intermittent starting. Clean the terminals with a wire brush and reconnect them tightly. If the cables are loose or frayed, replace them.
Fuses and Relays
Check the fuses and relays in the electrical panel. A blown fuse or malfunctioning relay can interrupt the starting circuit. Refer to the operator’s manual to identify the fuse locations, and replace any blown fuses. Also, inspect the relays, especially those associated with the starter and ignition system.
Step 2: Fuel System Check
If the battery and electrical connections are in good condition, the next area to inspect is the fuel system.
Fuel Filter
A clogged fuel filter can restrict the flow of fuel to the engine, preventing it from starting. Inspect the fuel filter for any signs of dirt, debris, or clogging. If it appears dirty or clogged, replace it with a new one.
Fuel Quality
Low-quality or old fuel can also cause starting problems, particularly in colder weather. Diesel fuel can gel in cold conditions, making it hard for the engine to start. If you suspect the fuel is the issue, drain the fuel tank and replace it with fresh, clean fuel.
Fuel Injectors
Dirty or malfunctioning fuel injectors can prevent the engine from getting the right amount of fuel. If the machine cranks but doesn’t start, this may be the cause. Professional cleaning or testing of the injectors may be necessary if you suspect they are clogged.
Step 3: Ignition and Starter Motor Check
If the electrical and fuel systems are functioning correctly, but the LX885 still doesn’t start, the issue might lie with the ignition system or starter motor.
Starter Motor
A faulty starter motor can cause the machine to fail to crank. If you hear a clicking sound but the engine doesn’t turn over, this could indicate that the starter motor is faulty. In this case, you may need to replace the starter motor or have it professionally tested.
Ignition Switch
A malfunctioning ignition switch can also prevent the engine from starting. If the switch feels loose or doesn’t engage properly, it may need to be replaced. Make sure the ignition switch is fully in the “start” position and that no dirt or debris is preventing its function.
Safety Interlocks
The LX885 is equipped with various safety interlocks, such as the parking brake and seat belt, which must be engaged for the machine to start. Ensure that all safety switches are properly engaged before attempting to start the machine.
Step 4: Diagnosing Other Components
If all the above systems are functioning correctly, but the machine still won’t start, there are a few other components that could be causing the issue.
Glow Plugs (for Diesel Engines)
For diesel engines, glow plugs are essential for starting, particularly in colder conditions. If the glow plugs are damaged or malfunctioning, the engine may struggle to start. Test each glow plug and replace any that are faulty.
Engine Sensors
Modern skid steers, including the LX885, are equipped with various sensors that monitor the engine’s performance, such as the crankshaft position sensor or the fuel pressure sensor. A malfunction in one of these sensors can cause the engine to fail to start. Use a diagnostic tool to check for any sensor-related error codes.
Step 5: Consult the Operator’s Manual and Dealer Support
If you've checked all the common causes and the machine still won’t start, it may be time to consult the operator’s manual for additional troubleshooting steps. The manual may provide specific information on error codes, maintenance schedules, and part numbers for replacement components.
If the issue persists, you may need to contact New Holland dealer support or a certified mechanic. They can run diagnostics using specialized tools to identify any deeper electrical, fuel, or mechanical issues.
Preventive Maintenance Tips
To avoid future starting issues with the New Holland LX885, regular maintenance is key. Here are a few tips:- Battery maintenance: Keep the battery clean and ensure that it is properly charged.
- Fuel system care: Replace fuel filters regularly and use high-quality fuel.

Transporting a 225DLC excavator weighing approximately 63,000 lbs and measuring 10.5 feet in width from Atlanta, Georgia to Fargo, North Dakota presents a classic example of long-distance heavy equipment relocation. This type of move requires careful planning, regulatory compliance, and coordination between the shipper, hauler, and state authorities.
Key Terminology - Oversize Load: A vehicle or load that exceeds standard legal size or weight limits and requires special permits.
- Lowboy Trailer: A semi-trailer with a drop deck used to haul tall or heavy equipment while maintaining legal height limits.
- Escort Vehicle: A pilot car that accompanies oversize loads to ensure safety and compliance with traffic regulations.
- Permit Routing: The process of selecting a legal and safe route for oversize transport, often dictated by state DOTs.
Transport Requirements and Challenges- Weight and Width Considerations
At 63,000 lbs and 10.5 feet wide, the excavator exceeds standard limits in most states. Legal width without a permit is typically 8.5 feet, and weight limits vary by axle configuration.
- Trailer Selection
A lowboy or detachable gooseneck trailer is ideal for this move. It allows for easier loading and keeps the overall height within legal limits.
- Permitting Process
Each state along the route—Georgia, Tennessee, Kentucky, Illinois, Wisconsin, Minnesota, and North Dakota—requires separate oversize permits. These permits specify allowable travel times, escort requirements, and route restrictions.
- Escort Requirements
Depending on the state, loads over 10 feet wide may require one or two pilot cars. Some states also restrict travel during rush hours or on weekends.
- Insurance and Liability
The hauler must carry adequate cargo insurance and liability coverage. Damage during loading, transit, or unloading can result in significant costs.
Field Anecdote: Midwest Excavator Relocation
A contractor in Iowa once relocated a similar-sized excavator from Texas to Minnesota. The move required two escort vehicles, a lowboy trailer, and coordination with five state DOTs. The hauler encountered a bridge height restriction in Missouri, forcing a last-minute reroute. Despite the challenges, the excavator arrived on time and under budget—thanks to a seasoned transport company familiar with heavy equipment logistics.
Historical Context: Evolution of Equipment Transport
In the 1970s and 80s, equipment transport was often handled in-house by contractors with their own trucks and trailers. As machines grew larger and regulations tightened, specialized transport companies emerged. Today, many contractors outsource long-haul moves to firms that handle permitting, routing, and compliance.
Recent Trends and Technology- Digital Permit Systems
States now offer online permit applications, reducing wait times and improving accuracy.
