I'm sure you would be better to solve the belt problems, axial drive is
a pain, no-one uses that if they can avoid it.  It sounds to me like
your belt is simply too small.  Get a toothed belt about 30mm wide, like
a cam belt only shorter, and you shouldn't have problems.

Thanks again.  I'll see what I can find.  Come to think of it the cam belt
in my eu2000 lasted 12,000 hours and was still usable and that engine
supposedly runs at something like 5000 rpm full throttle.  Not only that but
the cam gear/pulley is made out of plastic.

Axial drive is common on pumps. Try a Lovejoy coupler.

Here is a single B size belt connecting a 5.5HP gas engine to the
serious load of my home-made sawmill:

The engine was borrowed from my logsplitter where it drives the
hydraulic pump to full power through an L095 Lovejoy.

The 18HP tractor elsewhere on my gallery uses a B belt to drive the
transmission, and I put in another on the PTO shaft to operate the
hydraulic pump for the loader. The first belt there failed after 4
years, one cord broke and the belt rolled a quarter turn sideways on
the pulley, where it has no grip.

If you can fit a larger pulley the strain on the belt will be less.
Got machine tools?

Very interesting but I'll need to look at it some more.  Not sure what I'm
looking at but I understand how the idler pulley works.

I don't even have a drill press.  Finding a 5/8" pulley and having it bored
out by a machine shop might be my only option.

I can't seem to get your gallery to work but I did get a glimpse of your
loader for the lawn tractor.  Wow.  I have two old lawn tractors and was
wondering if that would actually work.  Does yours have a locking
differential?  Both of mine have open type differentials and one wheel slips
under rather mild conditions.
