Skid steer loaders are an essential tool for many industries, from construction to landscaping. Known for their maneuverability and versatility, these machines are capable of handling a wide range of tasks, from lifting heavy loads to digging and grading. However, as with all heavy equipment, skid steers can encounter issues that affect their performance. One such problem is hydraulic failure, which can significantly impact the loader’s functionality. In this article, we will explore the potential causes of hydraulic failure in skid steer loaders, specifically the John Deere 216B, and offer guidance on diagnosing and fixing these issues.
Understanding the Hydraulic System in a Skid Steer
The hydraulic system in a skid steer is critical for powering various functions, such as the bucket lift, tilt, and drive motors. It consists of several components, including a pump, valves, cylinders, hoses, and a fluid reservoir. The hydraulic pump is responsible for circulating hydraulic fluid, which creates the pressure needed to perform work. When any part of this system fails, it can lead to a loss of function, rendering the machine unusable.
Common symptoms of hydraulic failure include sluggish movement of the lift arms, unresponsive bucket controls, or a complete lack of motion in the skid steer. In the case of the John Deere 216B skid steer, users have reported complete hydraulic failure, which can leave operators stranded in the middle of a project.
Common Causes of Hydraulic Failure in Skid Steer Loaders
Hydraulic failure can occur for a variety of reasons, ranging from simple issues like low fluid levels to more complex problems such as a failed pump or clogged filter. Below are some of the most common causes of hydraulic failure:

1. Low Hydraulic Fluid Levels: One of the simplest causes of hydraulic failure is low fluid levels. If the fluid level drops too low, the pump will not be able to generate the required pressure, leading to sluggish or unresponsive performance. This can happen if there is a leak in the system or if the fluid has been used up due to extended operation without proper maintenance.
   
2. Contaminated Hydraulic Fluid: Contaminants such as dirt, water, or metal shavings can enter the hydraulic fluid system, causing damage to the pump, valves, and other components. Contaminated fluid can result in erratic operation, overheating, or even complete failure of the hydraulic system.
   
3. Faulty Hydraulic Pump: The hydraulic pump is the heart of the system, responsible for generating the pressure that powers the skid steer’s movements. If the pump becomes worn out or damaged, it may not generate enough pressure to operate the machine’s hydraulics, leading to a complete failure of the system. This can be caused by wear and tear, poor maintenance, or a manufacturing defect.
   
4. Clogged Hydraulic Filters: The hydraulic filters are designed to trap debris and contaminants from the fluid before it circulates through the system. Over time, these filters can become clogged, restricting the flow of fluid and reducing the system’s ability to generate pressure. In severe cases, a clogged filter can cause complete hydraulic failure.
   
5. Damaged Hydraulic Hoses or Fittings: Leaking hoses or damaged fittings can allow hydraulic fluid to escape, reducing the pressure in the system. A simple hose leak can cause the machine to lose power, and if left unaddressed, it can lead to more serious issues like pump failure or hydraulic fluid contamination.
   
6. Faulty Valves or Controls: The valves and control systems in a skid steer are responsible for directing hydraulic fluid to the appropriate parts of the machine. If these valves malfunction, it can prevent the fluid from reaching the lift arms, bucket, or drive motors, leading to hydraulic failure.
   

1. Check Hydraulic Fluid Levels: Begin by checking the hydraulic fluid levels in the reservoir. Low fluid levels are often the simplest and quickest fix. If the fluid is low, top it up with the recommended type of hydraulic oil. Be sure to inspect the system for any visible leaks that may be causing the fluid loss.
   
2. Inspect for Leaks: Check all hydraulic hoses, fittings, and connections for signs of leakage. Leaks are one of the most common causes of low hydraulic fluid, and they can often be the source of power loss. If a leak is found, repair or replace the affected component before refilling the system with fresh fluid.
   
3. Examine the Hydraulic Pump: A worn-out or malfunctioning hydraulic pump can be difficult to diagnose without professional equipment. However, if the fluid level is correct and there are no leaks, yet the skid steer still experiences sluggish or unresponsive movement, the pump may be the culprit. In this case, the pump should be tested for pressure output and inspected for signs of damage or wear.
   
4. Check the Hydraulic Filters: Over time, hydraulic filters can become clogged with contaminants, restricting fluid flow and reducing system efficiency. Remove and inspect the filters for any signs of dirt or debris. If the filters are clogged, they should be cleaned or replaced. Ensure that the new filters are installed properly and the system is flushed before adding fresh fluid.
   
5. Test the Control Valves: Faulty control valves can prevent the proper flow of hydraulic fluid to the necessary components. If the hydraulic pump is functioning correctly and the fluid levels are adequate, the issue may lie within the valves or control system. Testing the valves and electrical components can help determine if they are malfunctioning.
   

1. Regular Fluid Checks: Always check the hydraulic fluid levels before operating the machine. Ensure that the fluid is at the correct level and top it up if necessary.
   
2. Routine Filter Changes: Replace hydraulic filters regularly to prevent clogging and ensure that the fluid remains clean and free of contaminants.
   
3. Inspect Hoses and Fittings: Periodically inspect the hydraulic hoses and fittings for signs of wear, cracks, or leaks. Replace any damaged hoses to prevent fluid loss.
   
4. Use Quality Hydraulic Fluid: Always use the manufacturer’s recommended hydraulic fluid for your skid steer. Using the wrong type of fluid can lead to performance issues and system damage.
   
5. Schedule Professional Inspections: If you suspect a more serious issue with the hydraulic system, consider scheduling a professional inspection. A trained technician can use diagnostic equipment to check the pump, valves, and other critical components for issues.

Thieves are now targeting valuable machinery, often stripping it for parts or selling it on the black market. The financial implications can be devastating, especially when stolen equipment is integral to operations. In this article, we’ll examine the rising issue of equipment theft, its impact, and how businesses can take steps to protect their assets.
How Equipment Theft Affects Businesses
The consequences of equipment theft extend beyond the immediate loss of machinery. For many businesses, stolen equipment can lead to significant downtime, project delays, and the associated financial losses. When a machine is stolen, it’s not just the cost of the asset that’s lost—there are also repair or replacement costs, as well as potential legal fees if the thief is caught. In some cases, businesses may even lose client contracts or damage their reputation due to delays caused by equipment theft.
For construction companies, in particular, this can be especially problematic. Heavy equipment such as excavators, bulldozers, and cranes are essential for completing projects on time. If these machines are stolen, the business may have to rent new equipment at a higher cost, or in worse cases, even halt the project until the equipment is recovered.
The Methods Thieves Use to Steal Equipment
Thieves are using increasingly sophisticated methods to steal heavy equipment. Some of the most common techniques include:

1. Stealing Equipment at Night: Many thefts occur after hours when construction sites are empty. Thieves often target machines that are left unguarded, particularly those that are not locked properly or have poor security measures.
   
2. Fake Transactions: Some thieves pose as legitimate buyers or renters. They may approach rental companies or dealers, offering to buy equipment or rent it under false pretenses, and then sell or use the equipment for their own purposes.
   
3. Cutting GPS Systems: More advanced equipment often comes with GPS tracking systems, which make it easier to locate stolen machines. However, thieves have become adept at disabling or removing these devices, rendering the equipment much harder to trace.
   
4. Parting Out Equipment: Instead of stealing whole machines, thieves sometimes opt to steal valuable parts like engines, hydraulics, or specialized attachments. These parts can be sold individually, making it harder for authorities to track the stolen equipment as a whole.
   
5. Cross-Border Smuggling: Stolen equipment is sometimes smuggled across state or international borders to be sold in markets where it is difficult to trace. The ease of transporting these machines via trucks or shipping containers has only made the problem worse.
   

1. Invest in GPS Tracking: One of the most effective ways to deter theft and recover stolen equipment is by installing GPS tracking devices. These systems allow businesses to track the location of their machinery in real-time, increasing the chances of recovery if it’s stolen. Some systems even have geofencing capabilities, which send alerts if the equipment is moved outside a designated area.
   
2. Use Heavy-Duty Locks and Immobilization Devices: Simple physical deterrents such as high-quality locks, wheel clamps, and immobilization devices can prevent thieves from easily accessing the equipment. Many of these devices are designed to make it difficult for thieves to move or operate the machine.
   
3. Secure Storage Areas: When equipment is not in use, it should be stored in secure areas with restricted access. Fenced-in lots with proper lighting, security cameras, and even guard services can reduce the likelihood of theft. Some companies even opt for storage yards that are monitored 24/7 by security professionals.
   
4. Implement Employee Training: Employees should be educated on the importance of securing equipment when not in use. This includes locking machines, removing keys, and ensuring that GPS trackers are functional. Additionally, employees should be aware of suspicious activities around job sites and report them immediately.
   
5. Record Equipment Information: Keep a detailed inventory of equipment, including serial numbers, photographs, and any unique identifiers. This will make it easier to report stolen items to the authorities and increase the chances of recovering stolen goods.
   
6. Insurance Coverage: Businesses should ensure that their equipment is covered by comprehensive insurance that includes theft protection. While this may not prevent theft, it can help mitigate the financial impact if equipment is stolen.
   

The Rise of Compact Track Loaders in Snow and Mud
Compact track loaders (CTLs) have become indispensable in construction, landscaping, and utility work due to their low ground pressure and ability to operate in soft terrain. Unlike wheeled machines, CTLs distribute weight evenly across rubber tracks, allowing them to float over mud, sand, and snow. However, this advantage comes with a tradeoff—traction on slick surfaces, especially snow-covered or frozen ground, can be limited.
Rubber tracks, while excellent for minimizing surface damage, lack the aggressive tread needed to bite into ice or packed snow. This has led operators to explore aftermarket solutions like track cleats, screw-in carbide tips, and bolt-on traction aids to improve grip and maneuverability in winter conditions.
What Are Track Cleats and Why Do They Matter
Track cleats are external traction devices designed to enhance the grip of rubber tracks. They can be bolted or screwed into the track surface and often feature hardened steel or carbide tips.

Why Sand Accelerates Wear in Compact Track Loaders
Sand is one of the most abrasive materials encountered in earthmoving operations. Its fine granules infiltrate moving components, grind against metal surfaces, and retain moisture that promotes corrosion. For compact track loaders (CTLs) like the Case TR270, operating in sandy environments can lead to accelerated wear—particularly in sprockets, rubber tracks, and undercarriage components.
Unlike clay or loam, sand lacks cohesive structure. It shifts constantly under load, creating high-frequency vibration and micro-movement between track pads and sprockets. This dynamic friction wears down metal teeth and rubber lugs far faster than in cohesive soils. Wet sand is even more destructive, acting like a slurry that erodes surfaces and penetrates seals.
Case Study of Rapid Component Failure
One operator reported replacing both sprockets and tracks at just 430 operating hours. The second set of sprockets lasted only 183 hours, and the third round of replacements was looming at under 200 hours. This level of wear is far beyond typical expectations, where OEM undercarriage components often last 800–1200 hours in mixed terrain.
Such rapid degradation suggests a combination of factors:

• High-speed operation in abrasive terrain
  
• Use of low-quality aftermarket parts
  
• Lack of routine cleaning and inspection
  
• Inadequate tensioning or misalignment
  

• Sprockets with hardened steel teeth and deep root profiles
  
• Rubber tracks with reinforced carcasses and abrasion-resistant compounds
  
• Sealed bearings and bushings with sand-resistant seals
  
• Track rollers with hardened shells and replaceable sleeves
  

• Daily cleaning of undercarriage with pressurized water or compressed air
  
• Regular inspection of sprocket teeth for rounding or pitting
  
• Monitoring track tension and adjusting to factory specifications
  
• Lubricating pivot points with high-viscosity grease that resists washout
  
• Rotating tracks and sprockets if uneven wear is detected
  

• Avoid sharp turns that grind tracks against loose material
  
• Reduce travel speed to limit vibration and heat buildup
  
• Minimize unnecessary movement across abrasive surfaces
  
• Use alternate paths with firmer ground when possible
  

• Design work zones with compacted access paths
  
• Use geotextile mats or gravel overlays in high-traffic areas
  
• Schedule maintenance during cooler hours to reduce thermal stress

Several factors can contribute to contamination in and around the hydraulic pump area:

1. Dirt and Debris: The most common cause of contamination in the hydraulic system is dirt and debris entering the pump area. This can happen when the pump housing is exposed to external elements or when the seals are damaged. Any foreign particles can get into the system, clogging filters, hoses, and valves.
   
2. Hydraulic Fluid Leaks: Leaks from hydraulic lines or seals can lead to the accumulation of hydraulic fluid in unwanted areas, such as the pump housing. Over time, these leaks can cause contamination and affect the system’s ability to maintain proper pressure and flow.
   
3. Improper Sealing: If the seals around the hydraulic pump or pump housing are worn or improperly installed, fluid and debris can seep into the area. This can lead to contamination, which may affect the performance of the pump and other components.
   
4. Maintenance Neglect: Failing to clean the hydraulic system regularly or replace worn-out components can result in the build-up of contaminants, leading to inefficient pump operation and potential damage.
   

1. Decreased Performance: Contamination in the hydraulic system can cause the pump to work harder than necessary, which can lead to decreased lifting capacity, slower response times, and overall poor machine performance.
   
2. Overheating: Contaminants in the pump area can block proper fluid circulation, leading to overheating. Overheating can cause permanent damage to the pump, seals, and other hydraulic components, which are costly to repair or replace.
   
3. Increased Wear and Tear: Dirt and debris can cause excessive wear on the hydraulic components, such as the pump and motor, leading to premature failure and the need for expensive repairs.
   
4. System Failures: In extreme cases, hydraulic contamination can lead to complete system failure, causing costly downtime for the machine. This can be particularly detrimental to operations that rely heavily on the skid steer for continuous work.
   

1. Prepare the Equipment: Before starting any maintenance work, ensure that the machine is parked on level ground and that the engine is turned off. Always wear appropriate personal protective equipment (PPE), including gloves and safety glasses, to protect yourself from hydraulic fluid and debris.
   
2. Release Hydraulic Pressure: Before working on the hydraulic system, it’s essential to release any built-up pressure. This can be done by moving the joystick or hydraulic levers in all directions to relieve the pressure in the system. This step prevents any fluid from spraying out during the cleaning process.
   
3. Drain Hydraulic Fluid: If the hydraulic fluid is contaminated or if you plan to replace the filters, it is a good idea to drain the fluid before starting the cleaning process. Use the drain plugs on the hydraulic reservoir to remove the fluid safely.
   
4. Inspect the Hydraulic Pump Area: Once the hydraulic fluid has been drained, remove any covers or panels that expose the hydraulic pump area. Inspect the area for visible dirt, debris, or oil leakage. Take note of any damaged or worn components, such as seals or hoses, that may need to be replaced.
   
5. Clean the Area: Use a degreaser or solvent to clean the pump area thoroughly. Apply the cleaning agent directly to the pump housing, hoses, and surrounding areas. Use a brush or cloth to scrub away any dirt and grease buildup. Be sure to clean all areas around the pump, including the seals, valves, and hydraulic lines.
   
6. Inspect and Replace Filters: After cleaning the pump area, inspect the hydraulic filters for any signs of clogging or damage. If the filters are dirty or worn, replace them with new ones to ensure proper fluid flow and prevent further contamination.
   
7. Reassemble and Refill Hydraulic Fluid: After cleaning, reassemble any components you removed to access the hydraulic pump. Refill the hydraulic reservoir with fresh, clean hydraulic fluid. Make sure to use the manufacturer-recommended type and quantity of fluid for the L220.
   
8. Test the System: Start the engine and test the hydraulic system by operating the various functions of the skid steer. Check for any leaks, abnormal sounds, or erratic performance. If everything operates smoothly, the cleaning process has been successful.
   

1. Regularly Clean the Hydraulic System: Clean the hydraulic pump area and components at regular intervals, particularly in dusty or dirty environments. This will help prevent debris buildup and ensure smooth operation.
   
2. Inspect Seals and Hoses: Regularly check seals and hoses for wear or leaks. Replace any damaged parts to prevent hydraulic fluid from leaking into unwanted areas.
   
3. Change Hydraulic Fluid and Filters: Replace hydraulic fluid and filters according to the manufacturer’s recommended schedule to ensure the system is operating at peak efficiency.
   
4. Monitor for Leaks: Keep an eye on the hydraulic system for any signs of fluid leaks. Leaks can quickly lead to contamination and reduced performance, so addressing them early can prevent more serious problems.
