What About An Electric Power Trac?????

[BobRip]

Just a suggestion, could you put a really quiet muffler on a 180, and maybe sound proof the engine compartment, etc. I know it would make the machine less powerful, but it will still have better performance than an electric machine.

I have seen some very quiet small engines. Forklift that run on propane are very quiet. I don't know how they do this, so it may not be feasible in a PT.

I'll put it on my "To do as soon as I finish other things on my list" list.

I guess I'm lucky that my horsewoman/wife doesn't mind the PT in the barn. It's a major time & back saver!!!Of course, I have to be sure it's not leaking anything or I'm sure it would be a different matter!The horses aren't bothered much by it...even the high strung Arabian doesn't get too nervous after she's been around it a bit.

We've got a few electric fork lifts at work. They are not that much quieter than the propane powered combustion engine forklifts that we also have. Something to think about...

The little PTs run a hydraulic pump for the drive wheels and another pump for the lift and turning rams. That pump has to turn at 3600rpm to provide maximum pressure to the hydraulics. ON an electric powered PT, would you need one electric motor for the lift/turning curcuit and a seperate electric motor for the drive pump? I think I just answered my own question, as I think the newer PT400s have the pump shafts in series, so only one motor would be needed. However, it would have to be big enough and powerfull enough to turn that hydraulic fluid. How big of an electric motor would you need to replace a 18HP gas engine?

I have an old single-pump PT, but assume the power requirements are similar. I don't plan to mow with it. The motor I am going to mount is rated at 15 hp peak, and 8 hp continuous. I plan to run it at 48 volts, which should give me about the right RPM.

This project, and the electric boat projects ahead of it got a bit of a setback on Sunday when some lovely children started our 2240 John Deere and ran it through the workshop. Steel doors at both ends destroyed, miscellaneous tools crunched, etc. (Gauges broken off the torch kit but no oxygen or acetylene released.) Extent of damage still unknown, but enough to require a lot of work before fun projects are back on line.

Yikes! I hate to ask if they were friends, family or trespassers. Hope you get things squared away soon.

Trespassers, identity unknown. They ran when I drove up earlier. I looked around and assumed they wouldn't come back. Wrong!
What I doubt they know is that the tractor, carrying a 12 x 15 foot corrugated steel door missed a man inside the building by about 2 feet. I am sure they didn't know he was inside when they got it going and jumped off. They may have seen him run to turn it off when it fetched up against the far end doors and sat with the rear wheels spinning on the concrete floor.

Wow! Glad no one was hurt and hope you catch 'em.

I AM INTERESTED. KEEP ME IN THE LOOP.
