Farmall M throttle and steering

bja105 · Apr 13, 2014

Is there a common problem that would make the throttle change when the steering wheel is turned?

My friend has a narrow front M that he uses to run a belt pto. When he is driving, the engine races when he turns.
Parked, I can see that the throttle moves when we turn the steering wheel.

Are there friction discs in the hand throttle assembly? His is held by a tarp strap, I don't think thats an oem tarp strap.

Here is the tractor working.

Thanks
Jason

Never seen a baler ran like that before. Is the tractor missing a PTO or the baler. Concerning the throttle and steering, the only connection is they are attached to the same steering post. If your throttle is the newer style with a friction disk instead of teeth it doesn't take much for the throttle to move on its own if the disk is worn or if the bolt to tighten it down needs tightening. New disks are available and you can try tightening the bolt that holds the 2 halves together. If you have an older style throttle with teeth them probably some of the teeth are worn down so it doesn't hold.

I have the same throttle and mine will work down when
running down the road. It is fine grinding feed as it doesn't do it
when it is sitting still.

Turn the bolt on top of the spring. Chances are that once it is tight enough to work perfectly it will be so tight that it will put his shoulder in a snit. That's how mine is and it is all new!

Is the steering pedestal loose? My Super M changes speed when I climb on it by grabbing the steering wheel.

The friction disk in the lever at the steering wheel support is worn out, and the spring holding the two together is toast. Find a tougher spring at a good hardware store, and a new bolt. The friction material can be made from a shoe sole, or rubber belting from a conveyor, about 3/16" thick. Thickness not critical. Make sure the steering shaft is not touching the throttle control rod going toward the gauges. If it is, Bend it outward so as to not touch. (ditch the tarp strap) The tractor needs some TLC, but if running, is worth making it nicer. Jim

Is that green baler a 224T? We had one back in the day, it got sold out from under me before I knew it, I still wish I had it...btw, do you just bring the hay to the baler?

If the throttle moves when you turn the steering wheel with the tractor parked remove the engine cover and check the throttle linkage just in front of the fuel tank. Is there something attached to the steering shaft or universal joint and throttle linkage? The throttle linkage at this point can wear badly with time and use. These are parts 12, 13 and 14 in the attached picture. They sit right beside the steering shaft.

Yes, the steering pedestal is loose, it moves also when the wheel is turned. I am not sure if that is all of the throttle movement, but its a start. I will also look at the friction discs and the linkage mentioned. It will be a few weeks before we can get into it, but hay making season is a while off.

The neighbor brings the hay to the baler. He used to use a hay loader, but now he has a haybuck.

He drives the team down the windrow until the forks are full, then raises the forks and brings the load to the baler. He lowers the forks and backs the team out. One or two boys fork the hay into the baler while another boy stacks the bales on the wagon. He has five sons, and they all dread hay making!
