Diagnosing problems in the John Deere systems
The first name for all what is related to John Deere tractors. Their distinctive green tractors are tough and reliable. This company manufactures many models as utility tractors, four wheel engines and combines. These are the lines of superior machines. However, as with many heavy farm equipment has many moving parts and cracks inevitably occur in the hydraulic system. There are several steps to diagnose before calling the mechanic from John Deere which can be an expensive visit.
- Check the oil level if the system pumps is noisy. Fill as necessary. Replace oil and filter if the oil viscosity is not correct. Check whether the ventilation cover of the reservoir is locked.
- Check air leaks in the internal air pump and accessories; if there is a system of pumping fluid check oil level. If necessary, replace it. Check if the valve is partially open and close it.
- Check if the levers surround the pivots rise and fall correctly. If necessary, lubricate the link. Check the cylinder axes if is bent. Make sure the cylinder and the hub are not overloaded. Entry checks to see if there is fluid low coming from the pump.
- Check the auxiliary hydraulic bucket handles if not lean back or forward or too slow. Check if the handle is blocked in the holding position and put it in neutral.
- Preselecting opens the valve if the hydraulic oil overheats. The passage of oil to the engine could be closed.
Tips & Warnings :
- If the hydrostatic pressure load is low, the oil level in the reservoir may be low. The load lines may be covered, compared to the same problem.
- For a noisy pump system pumps cannot be centered. It may also be that the hand brake is engaged. Check that the suction line is not blocked.
- If there is no pressure in the hydraulic system, the hydraulic pump can be worn. It may also be the exhaust valve which is damaged. For this problem, see the sales agent of John Deere.
- For problems with levers that are not properly raised or lowered, this could indicate that the rotary pump is damaged. Consult your sales representative of John Deere.
- If the hydrostatic head pressure is low, this may indicate a malfunction in the exhaust pressure of the load. The exhaust will need to be replaced by a John Deere technician.
