How to Fix John Deere 9550 Combine Problems
1. 9550 Electrical Problems
Many users as reported by them face electrical problems in the John Deere 9550 combine. The users experienced that the tractors do not go above idle mode.

Furthermore, you can also repair the control unit if there is a minor defect.
2. 9550 Fuel Problem
On the other hand, the users of John Deere 9550 also ran into the fuel problem. This problem is related to the fuel pump, fuel lines, fuel injectors, valves, and the fuel filter of the tractor. Firstly, inspect the fuel pump of the tractor and if there is any malfunction with it then replace it as soon as possible. By doing this, the problem should be fixed.
Secondly, inspect the fuel lines of the tractor. It is because if there is any leakage or blockage in the fuel lines of the tractor then it will disturb the fuel consumption of the tractor. Thus, wash and clean the fuel lines if they are blocked. On the other hand, if the fuel lines are leaking then replace the pipes from the service center to fix this problem. Moreover, the unadjusted valves can also contribute to this problem. Therefore, adjust the valves to fix this issue. Aside from the valve issue, you can also run into this problem if the fuel filter of the tractor is clogged. If this is the case, then replace the fuel filter to fix this problem permanently.
3. 9550 Transmission Problem
The transmission problem is also one of the most common problems that the users faced in the John Deere 9550 combine. The users experienced that the tractor does not shift into second or third gear. This can be diagnosed by inspecting the gear wire, gear oil, and the gear linkage of the tractor. To troubleshoot this problem start inspecting the gear wire and if there is any defect in it then replace it from the nearest auto zone. Secondly, inspect the gear oil.
If the gear oil is lower than the specified level then this problem can pop up. If this is the case, then top up the gear oil up to the specified level to troubleshoot this problem. Thirdly, check the gear linkage of the tractor because if the gear linkage is too tight then this problem will show up. Therefore, if this is the case then loosen the gear linkage to resolve the problem.
Aside from the gear-engaging problem, the users also experienced a noise coming from the transmission box. This problem is generated if the parts of the transmission box are damaged.
