I have a idea.I was thinking about using a
small rearend out of a old garden trakter,for
a drive unit.You would need one with a break
on each whell.Think about it if you are mowing
and one whell starts to spin the other one stops
so by pulling the break on one side the other
side keeps going this would alow turning.I can
find old transaxel rear ends for around 20.00
just take the wheels of bolt on some sprokets
and go.The only draw back i see is you will have
a gear shift and it would have alot of power and
little speed.But the speed could be fixt by changing sprokets.You would need a cluth so you
could shift gears but a cintrifical cluth schould
work easy this could all be done probubly for
around 50.00- 75.00 thats a lot cheaper than
hydrolics.

Does any body know how the drive system on the "Hollands hilla.go.hike" worked? It claims to be able to turn on its own axis. This design might be of some use to the adaptation of a hydrostatic drive system?

I have been looking for the plans for that unit for a while now. I beleive that it is a hydro design. It would have to have independant control of each side to do what they say it will. So if you see the plans anywhere let us know!

Hello All ;Nice website, Just reading your discussions and wanted to share this with all . Larry Miller
asked about using a rear end of a lawn mower to build an ATV , here's what I did 10 odd years
ago. I found an old Chushman 3 wheel meter maid
with a two cylinder air cooled engine and a small
3 speed transmssion . First I removed the cab and
added another 3 speed transmission behind the first one , this gave using 1st or 2nd gear of the added tranny an option of low or medium range . ( I coupled the two by making an adapter
out of the center of an old clutch disc and a piece of pipe and welding it to the slip yoke)
The rear was a worm gear type and as Larry Miller
said the brakes on either side were connected to
two separate master cylinders. I wanted a full track laying vehicle so the tires were removed
and sprockets made to fit the conveyor track, only after approximately 10 miles the spider gears started to eat themselves up . I them
put a rear from a small Ford car --I think it was
a Maveric , anyway I had to shorten it but the
point is DO NOT UNDERESTIMATE the strain on the
differential if you try tracks, knowing that now I would suggest using a 1/2 ton or heavier rearend shortened up . I would not think that a wheeled vehicles would tear up so fast .
