Suppose you are facing this issue. Then there are the only things that could be faulty.

If that is the case, replace it, which can be bought from the nearest customer’s service center. You should call the mechanic and ask him to check if your injectors are working perfectly with no delay.

 If there is any delay, then the timing of your fuel injectors needs to be adjusted. If the problems mentioned above are not there, your tractor’s engine tappets are too tight. All you need to do is call the service center and get your tractor tuned.
