I have a deere 756 tractor starts and runs idle but does not power up or accelerate, ok, i ried to adjust the linkage

Hi, let's see if we can work together to get to the root of your problem! will try my best to help!

Does the fuel shutoff move freely? Did tractor quit under use?

Does the fuel shutoff move freely? Did tractor quit under use?

Does tractor kill with pull cable, not with the key? This is a 756, not a 755?

i'm confused, I look under Deere and find only 755 compact tractors. It shows a drop in injection pump, not a gear drive injection pump. Is this correct? Like this one.

Three cylinder engine.

On the side of the governor housing, just ahead of the injection pump, is the kill lever housing. remove the cover and see if you can determine if the link going to the injection pump is free and moving. If the linkage is not free, the injector pump may have a stuck injector body. Then the injection pump section would have to be removed and repaired.

Sorry, I thought i linked it. Here it is , the cover that the kill cable attaches to.

Did you remove the cover?

OK< should be some kind of cover that can be removed, to see the governor linkage. If not, the injection pump body will need to be removed.

No, the part is internal to this lever.

The link I sent shows a cover, but you say there is no cover behind the stop lever?

# 6 is the gasket for it. 7B would be the cover.

YES

You have no 7A, you have the 7B and it is attached.

OK< there will be an internal link that goes toward the injection pump, this has to be free, and should be spring loaded, you should be able to move it and it should then return to the rest position. If it does not move, need to find the stuck injector body in the three section pump.

Back and forth and should spring back.

trutle ??

This link goes to the injection pump and rotates the injector bodies to increase the rpm.

It may not be connected to the injection pump pin.

No, the governor has to react to the throttle.

Yes, put the cover on and see if it still does the same thing. It may have been stuck and now will work.

Let me know.

That is the injector return line that connects the injector return, to the fuel tank return. It could leak, but should not affect overall operation unless the return is plugged back into the tank,

Thanks!
