 Topic: Allis Chalmers 720. Can I use the foot clutch?
Posted: 09 May 2025 at 7:50am |

Reading through the operators manual on this tractor. It doesn't say much about the foot clutch pedal besides use it for starting the engine and emergency stops. So far as I can tell it just detensions a set of dual belts. I don't see whay I can use it as a normal clutch especially as mine has a loader but I don't want to break something. Can I use the clutch normally? It'd be awful handy when using the loader.

Other than an increase in wear of the belts and pivot hardware from the "extra" disengagement/engagement, it shouldn't be a problem. The increased wear and tear may be minor overall depending actual usage. With the 620 and 720 I had, mostly used the hydro even with the front mounted snowblower.

Ok, yea I'd expect the belts to not last quite as long. This thing is going to have an easy life with me. I got tired of breaking stuff long ago so now I always try to go easy. Even if it's not as fast it still beats a shovel and wheel barrow and downtime slows you down anyways.

only time i use the clutch is starting and hitching up somthing just pick a gear so you are using most of the range of the stick. dont use the hydro stick like you are swinging a base ball bat and it will be fine

I have a front end loader on this thing. Not sure how it's going to work out trying to control the loader, running the hydro lever, and steering at the same time. I'd like to be able to use the clutch.

Keep in mind that the clutch stops the shaft that runs the transmission/hydro, the pump, to allow you to change gears. Seams to me this would be hard on the hydro by stopping the flow of fluid that runs it in order to move the tractor when you release the clutch?

I was only thinking to do this when I'm going into a pile with the loader. Besides that I could run it normally. I'll keep it in mind though and try to practice getting a load on with hand controls only. I don't know how it could harm it but I don't know hydraulics.
