Make mount bracket for front of tractor, but leave gen engine on it and run it when used. OR, a little trailer for the back? Then put a hitch on that little trailer to put on the next implement you wish to tow to site and use. I'ld leave it alone and use as designed myself.

I like GL's idea of a small trailer!

I read that generators run in reverse will open a black hole...

After doing somemore research, and head scratching, I decided to

go ahead with this project.

This is what I've accomplished so far.

My brother will be making up the stub shaft with taper today.

I have correct size pulley. The electrical panel, I will change

and mount ontop of the gen.

Being the engine PTO pulley is 4" dia. and the gen pulley is 2.75", there

wasn't any room to use an idler pulley to act as a clutch/tensioner.

So, I hinged the gen mounting plate, so it could be the tensioner.

I'm looing for ideas, on what I can do there, so engagement/disengagement

can be quicker, than pulling out wrenches.

 

I decided to not keep this gen/motor as it was, as I already have several

newer stand alone generators, and I didn't want another Techumseh

to maintain.

Once you have it set up for the belt, could you figure out how to use this type latch to hold in place?

Yes Kenny!!!! A flat bar standing up between the adjustment bolts. Holes in that flatbar.

And that springy thingy on the gen base. I might even have one of those.

I'm not sure on your pivot point for the generator. If that gives enough shorter distance for the belt to be put on easily, then the weight of the generator should put tension on the belt. Then a bit more hand pressure to lock it in place. Just have to make sure you don't have too much tension on the belt and shaft going into the generator. Just an idea to look into. That latch is something I found Googling boat trailer tie down latch. I was looking for the type of latch that has the chain that hooks to the back of a boat to hold it on the trailer. That would make it a bit more adjustable.

That latch could be just to hold the gen up, when disengaged.

Gravity should work to engage, and the nuts, adjusted so as not

to apply too much pressure on the shaft. If gravity doesn't work

I have a some of those black rubber bungies with a closed loop

on the one end. They're used as battery hold downs.

 

Did you find those straps?

The ones I am thinking about were used on older trailers at the back. Everything now is using nylon straps instead of the chain. I have some small ones out back, just no pics handy of them.

 

 

EDIT: I went out and got one. Took a pic for you.

I've never seen those before. You could probably make those up, using those mini chain binders. Those

springs where used on the old cable steering systems in boats, 40 years ago.

Yep! Old School stuff.

I got this thing assembled, and sort of tested yesterday. The belt I had was a bit to

long, so it slipped, and the gen never got to full RPM. But it did make power.

 

It was a real trick to get it assembled, and shimmed, so as not to put any

side load on the taper shaft.

I took apart, and used several feeler gauges, and shimmed around the armature, to

get it centered in there, and then had to get the shims out of those oval holes in the casing

after everything was tightened up.

Ever thought about using 2 bearings with the pulley in between?

Thought for a minute that you had my generator. My husband took the generator out of our RV to rebuild it, then he passed away. The generator was taken by some "scrappers" who came to get some old cars. By the time I missed it, it was long gone. I'm more vigilant now, but I couldn't have reinstalled it anyway. Good luck with yours, beware the "scrappers." Mine was a generac.
