Clutch question
« on: May 14, 2009, 06:35:23 pm »
I hope this is a good place to post this. I have searched posts and found that the electric pto style clutch doesn't hold up for racers due to snuffing out. But I am going to atempt to build a gas powered wagon similar to the dr power wagon. I am using a tecumseh formula 10 hp for the motor. And a hydrostatic transaxle out of a newer murrey, ( unsure of model). It will be geared down to a crawl speed. Now does anyone think the electric clutch might work in this application considering it will always be engaged with transaxle being in neutral first? I think I might be fine but am unsure when loaded with weight. Would like payload to be around the 800 lb range. If I use one off a larger motor, say a 25 hp kohler, does the torqe rating go up? I have to find a way to engage clutch without linkage. Cable might work but would be a weak point, The electric clutch would be PERFECT if it will hold up. Any advise would be greatly appreciated. I could post pics of the build if anyone is interested.

with a hyrdrostat you don't need a clutch moition is control by your direction (forward/reverse control to include neutral.

So I can run direct belt from enging pulley to transaxle pulley. How com the murrey I pulled the transaxle out of had the pulley clutch to disengage drive?

It may have been for the mower deck, hydrostatic transmissions dont need clutches.

Also how are you gearing it down? from what i understand you can just do a pulley swap on a hydro.

It disengaged the belt for the actual brake. On commerical zero turns its all controled with the gosticks no brakes except for emergency brakes.

Thats kinda what I want. I wanted to have a lever on the handle bar that when you held it down it engaged drive and released the brake. Kinda like the safety lever on a push lawnmower only controlling brakes also due to weight being used on wagon. As far as gearing it down thats hard to explain, I'll actually be running the tires on separate spindles than the transaxle. Using chains in between. I'll use 9 or 10 tooth sprocket on transaxle and a 14 or 15 tooth on drive spindles. Motor and transaxle on the back with one swivel tire, and drive tires on the front. I would like to use individual kart brakes (band) in each side of axle to assist in steering. Even if I don't have to have a clutch I would like to incorparate one anyway just as a saftey aspect.

I started a large wheelbarrow with a two cycle engine one time. It's still around ,but other projects have taken over in the years. Different is always interesting. Get some pics as you build.
