Throttle Control

[willor]

Thanks in advance for any help you guys can provide

I own a Ferguson TO35 and am having problems keeping it from running at high RPMs. While bush hog mowing recently, I hit a high patch of dirt and the tractor bogged down quickly. Before I could raise the 3 point hitch the tractor made a pop and nearly died. I picked up the mower and the engine revd back up. Since this time I have trouble keeping the engine from racing to high RPMs. The engine will quickly creep up to high RPMs if I don't hold the throttle down. I think it is more than just the adjustment on the friction plate on the throttle, because the throttle also seems more sensitive. Before this happened I could move the throttle 45 degrees to go through the range of engine speed. Now it gets to high RPMs quickly if I move it a small distance (5 degrees). It seems as if something in the throttle adjustment changed.

i would first check your throttle linkage all the way to the carb visually to make sure nothing is loose. i would then suspect a fuel line block making it run lean

Sounds like something in the governor linkage or the governor itself has changed or come apart.

It is most likely that the Engine Governor needs resetting, they can be very sensitive when this is the case. No matter what the problem actually turns out to be you should reset the governor to make sure that it is OK. If you need the information to reset the Governor, if you email me at:- [email protected]
I will send it out to you.
Hitting a patch of dirt like you say you did and having reset the governor may not prevent the engine dieing like it did, as the peripheral speed of the blades on the "Hog" is so high, hitting that dirt is like applying the brakes and does require an awful lot of power to keep it running. If the ground is not level or flat; and there is always the danger of the blades hitting dirt, then you are running the "Hog" too low, remember it is for cutting scrub or grass, not levelling dirt, plus every time you hit dirt you are taking the edge off the blades and making it much harder to drive. If the blades have a good cutting edge it will be a lot easier to drive and will not work the tractor as hard...John

Thanks for all the suggestions. I will try and see if I can get the old girl running better.
