To30 governor issues?

K.Campbell · Sep 9, 2019

Well today I fired up my ferguson To30 and headed to the woods with bush hog attached. When I left
My driveway it felt like something slipped and then the tractor just fell on its face with no governor action whatsoever. I took it back to the garage and made sure that all springs were intact and throttle was had not slipped. All looked good. I took carb linkage off to check and see if the governor rod was moved freely, it seemed very tight and the forward movement was very little. I think I ll have to tear into it and see how the governor looks... any thoughts?

With the engine off and the dash lever set to fast, the carb should be spring loaded to full open position.

Bring the dash lever to idle, the carb should be closed against the idle stop.

Possibly the U bolt slipped up above the governor link where it attaches to the rod from the dash lever.

If the U bolt did slip, that is where the full speed RPM is set. Be sure to get it right, don't want a runaway.

could that cause a " dead governor" I mean I have literally NOTHING. I mowed with it anyhow, but in tall grass it nearly stalled a couple of times, on the way to the woods there are a couple of fairly steep hills, normally no issue with the old ferguson, but today it nearly stalled just climbing the hills. Granted I was in hi and in 4th gear.. but as I said normally the governor kicks in and it climbs the hills easily.
I noticed that the governor arm was stiff and had no forward play. I ll try and readjust tomorrow as you have suggested..that s what it felt like when it started acting up, felt like somthing slipped.

I think you are on the right track with the U bolt slipping. Had it happen to me. You can start it up and move the linkage coming from the carb to the
governor and see if it revs up and is still governed, governor starts pushing back. If that is the case then definitely slipped ubolt

If it slipped, that is like running with very little throttle.

There is a plunger that comes down to push the throttle closed, a safety feature in case of governor failure to stop a runaway. If the U bolt slipped, the plunger and governor spring will stay down and try to hold the throttle closed, thus very little movement of any linkage.

where is the plunger located? I ve adjusted the u bolt with no success. It s still a dead governor meaning it almost dies climbing a moderately steep hill

any other things to try? I ve pushed the governor rod while it was running and didn t notice much push back...done that test at idle and partial full throttle. The governor is a simple part, if somthing goes wrong with it doesnt it normally just rattle bang and fall apart? Is there anything internal that could cause the issue I m having? I ve always had a very slight front end rattle... that hasn t changed..just going up hills, and working under a load. Up until this event, tractor would pull hard up a hill and work hard under a load.

i think I may have got it, I messed with the throttle rod adjustment as well as the u bolt adjustment... man that is one little picky adjustment! I still need to do some fine tuning, but now I m half afraid I ll mess it up! I need a littlemore governor action, the ubolt is t quite where it needs to be...but I adjusted it to where the throttle was wide open and to where it was fully closed, as advised.
