Adding traction to a beavertail and trailer deck is essential for safely loading tracked and wheeled equipment, especially in winter conditions. Solutions include welded key stock, removable guide rails, rubber mats, and strategic use of scrap materials to reduce slippage and side drift.
The challenge of loading in icy or uneven conditions
Loading heavy equipment like excavators or skid steers onto trailers becomes hazardous when snow, ice, or slope angles reduce traction. A common scenario involves a tracked machine sliding sideways on a steel deck, especially when the trailer is slightly tilted or the tracks are wet. Even a few inches of misalignment can make a 10'6" wide machine unsafe on an 8'6" wide trailer.
Operators often rely on placing the bucket down before the tipping point to control the breakover, but this technique alone doesn’t prevent lateral drift. The risk increases with narrow trailers, limited loading space, and winter conditions.
Welded traction enhancements
One of the most effective methods is welding ½-inch square key stock (also called bar stock) across the deck and beavertail. These bars act as mini cleats for the grousers to grip during ascent. For added durability:

• Weld key stock every 6–8 inches across the loading surface
  
• Use flat bar underneath for reinforcement
  
• Ensure welds are continuous and flush to avoid catching tires
  

• Welded permanently for dedicated trailers
  
• Bolted or pinned for removable use
  
• Positioned to allow clearance for other equipment like skid steers
  

• ASV or Cat MTL tracks, which have embedded steel and high friction
  
• Bolt-on tire treads or sliced truck tires
  
• Conveyor belt strips nailed or bolted to the deck
  

• Wood ashes spread on the deck for grip
  
• Old tires laid flat under the tracks during loading
  
• Scrap bolts or rebar welded to the beavertail edge for grouser bite
  

• Ensure the hinge point between beavertail and deck has a sharp edge or welded bar for track engagement
  
• Avoid ground-bearing ramps in winter; consider non-ground-bearing detaches for safer breakover
  
• Keep the deck clean and dry before loading
  
• Use spotters and side mirrors to monitor alignment
  
• Always chain down immediately after loading to prevent movement

While the 420D has an excellent reputation for its reliability, problems with its hydraulic components can affect its performance. A non-moving boom is typically a sign of an issue within the hydraulic system, which powers the boom’s operation.
Common Causes of Boom Movement Failure
The failure of the boom to move can result from several potential problems. Some of the most common causes include hydraulic issues, mechanical problems, or electronic malfunctions. Below are some of the most likely culprits.
1. Low Hydraulic Fluid Levels
One of the most straightforward causes of a non-moving boom is insufficient hydraulic fluid. The hydraulic system of the 420D backhoe powers the boom, and if the fluid level is low, the hydraulic pump cannot generate enough pressure to operate the boom.
Solution: Check the hydraulic fluid levels using the dipstick provided on the machine. If the fluid is low, top it up with the recommended hydraulic fluid. Make sure the fluid is clean and free of contaminants. Low or dirty fluid can compromise the system's ability to work efficiently.
2. Clogged Hydraulic Filters
The hydraulic system of the 420D backhoe uses filters to prevent dirt, debris, and other contaminants from entering the system. Over time, these filters can become clogged, restricting the flow of hydraulic fluid and reducing the system's pressure. This can cause the boom to become sluggish or even fail to move altogether.
Solution: Inspect the hydraulic filters and replace them if they are clogged or damaged. It is essential to replace filters at regular intervals as part of the backhoe’s preventive maintenance schedule. A clean filter ensures proper hydraulic fluid flow and optimal performance.
3. Faulty Hydraulic Pump
A malfunctioning hydraulic pump is another possible cause of boom movement failure. If the pump is not generating sufficient pressure or is damaged, the hydraulic system cannot operate the boom effectively. Common issues include worn-out internal components or air trapped inside the pump.
Solution: If the hydraulic fluid levels and filters are in good condition, and the boom still won't move, it may be necessary to inspect the hydraulic pump. If the pump is damaged, it should be repaired or replaced. This is typically a more advanced repair that may require a mechanic's expertise.
4. Leaking Hydraulic Hoses or Fittings
Hydraulic hoses and fittings are responsible for carrying pressurized fluid to the boom and other hydraulic components. If these hoses develop leaks, the hydraulic pressure can drop, preventing the boom from operating. Leaks can occur due to wear and tear, corrosion, or improper connections.
Solution: Inspect all hydraulic hoses and fittings for signs of wear, cracks, or leaks. If any hoses are damaged, replace them immediately. Tighten any loose fittings, and make sure that all connections are properly sealed.
5. Faulty Hydraulic Valves or Solenoids
The hydraulic valves and solenoids on the 420D control the direction and flow of hydraulic fluid. If one of these components fails, it can prevent the hydraulic fluid from reaching the boom or prevent the proper movement of the boom.
Solution: Test the solenoids and valves to ensure they are functioning correctly. If a valve is sticking or a solenoid is not activating properly, they may need to be repaired or replaced. Proper diagnosis can often be done with a hydraulic pressure test.
6. Electrical or Control System Issues
The John Deere 420D backhoe has an electronic control system that works with the hydraulic system to control the boom. If there is an issue with the electrical system, such as a faulty switch, wiring, or sensor, it could prevent the boom from moving.
Solution: Inspect the electrical wiring and control switches for damage. Ensure that all connections are clean and free from corrosion. If the electrical system is not functioning correctly, consult the backhoe’s wiring diagram and repair any faults in the circuit.

3. Consider Warranty and Return Policies
   • When purchasing final drive motor parts, make sure that the supplier offers a warranty and a return policy in case the part doesn’t fit or function as expected. A warranty gives you peace of mind and ensures that you won’t be stuck with defective parts.
     
4. Evaluate Customer Service and Support
   • Choosing a supplier with excellent customer service can make a huge difference. A knowledgeable team can help you navigate the process of selecting the right parts, guide you through installation, and assist with troubleshooting if problems arise after purchase.
     

• Buy in Bulk: Some suppliers offer discounts when you buy multiple parts at once. If your equipment fleet requires regular maintenance, buying parts in bulk can save you money in the long run.
  
• Consider Rebuilt Parts: Rebuilt or refurbished parts can offer a good balance between cost and quality. These parts are reconditioned to meet factory specifications, making them a more affordable alternative to new parts.
  
• Look for Seasonal Deals: Many suppliers offer discounts during certain times of the year, such as the end of the fiscal quarter or during off-season periods when demand is lower.
  
• Check Multiple Sources: Don’t settle for the first price you see. Compare prices from different suppliers to ensure that you’re getting the best deal.
