Drott 40 Won’t Move: Troubleshooting Forward and Reverse Issues

[MikePhua]

Problem Description
A user reported that their Drott 40 was unable to move forward or reverse despite the engine running fine. They described how the machine was stuck in place and asked for help identifying possible causes and solutions.
Possible Causes
Other members suggested several potential reasons for the issue. Common culprits included low or contaminated hydraulic fluid, a clogged filter, or air trapped in the system. Some mentioned that worn or damaged drive clutches could also be the source of the problem.
Hydraulic System Checks
Advice was given to check the hydraulic fluid level and condition first. If the fluid looked dirty or had not been changed in a long time, flushing the system and replacing filters could help. Inspecting for leaks or loose connections was also recommended.
Transmission and Clutch Inspection
Several responses highlighted the importance of inspecting the transmission linkage and drive clutches. Users noted that stuck or worn-out clutches might prevent the machine from engaging the drive. Adjustments or replacements might be necessary if parts are damaged.
Additional Suggestions
Some recommended checking for any blocked lines or faulty control valves that could restrict fluid flow. Ensuring that all safety switches and linkages are functioning correctly was also advised, as a failed neutral safety switch could keep the machine from moving.
Conclusion
When a Drott 40 won’t move in either direction, the issue is often related to hydraulic fluid, filters, clutches, or transmission linkages. A step-by-step inspection and regular maintenance can help identify the root cause and get the machine back in working order.
