Dumb H govenor question

I just need to verify what I think I know...

A person cannot adjust an H govenor while the tractor is running, correct? I think you cannot because there is oil that does into it, but since I don't see anything in writing, I just want to verify.

That being said, I guess the only thing I'm adjusting is the maximum movement, and the stop bolt, right? The reason I'm going to adjust it when it's done is because when I pull the throttle back to full, I get a lot of resistance and pull back. The tractor won't stay at full throttle because there is so much tension.

Hello mike,
The reality is that you should not adjust the governor.
The lever is used to make the governor move through its full (designed) range of speeds. Your speed control handle should move the governor control arm (back side of governor toward engine block) through its full range of motion.
If you take the rod out of the governor arm, the arm should move from all the way forward to a stop to all the way back.
Your hand lever should make this happen.
Move the hand lever to full speed position with the governor disconnected at the governor arm.
Then pull moderately on the rod while pulling the governor arm to wide open position. The link rod should now just go in the hole. if they line up, (or almost line up, but pulling a bit farther than the max governor arm will allow) the hand lever is doing what it needs to do. If it does not pull far enough, adjust the rod shorter.
If the hand lever slips down toward idle, and the speed decreases, the throttle lever needs service. If it is the stock notched, or saw tooth system it needs some three cornered filing on the teeth to help them stay in place (and maybe a new somewhat heavier spring at the pivot)
If it is a friction type, new leather washers (cut from an old boot from a thrift store), and a heavier spring will do it.
Expect the first 1/3 of the lever travel to do nothing. That is typical. Jim

It can be adjusted when running. Just very messy.

I can't help with your problem, because mine does the same thing. Upto 3/4 throttle no problem try to go to wot and it pulls the throttle handle back. That id with a new knob and throttle plate.

I have not got around to fixing it yet or looking into it. So I am going to watch and see what the possibilities are to fix it.

Thanks Jim. Saved for when I have that put back together in a couple days.

Expanding a bit on Jim’s post: If the engine reaches full RPM with the governor handle pulled/held all the way back, the governor is adjusted correctly. The handle tension problem then involves the governor control rod adjustment.

The governor control rod is the rod runing from the handle at the steering wheel to the bell crank over the manifold. The end of the rod is fitted with a “governor control rod equalizer” - an elongated C-shaped metal clip containing a pair of springs and a swivel nut. And yours is likely is out of adjustment.

Anyway follow Jim’s procedure to adjust the swivel nut in the equalizer – your problem should disappear.

Will do. Thanks Bob.
