Just wanted to share this with you all. I was looking for a durable snowblower due to the heavy snow we just all had in the Northeast.
My 9hp Craftsman (NOMA) did okay but had a little issue getting into the packed heavy snow (understandable).
My neighbor down the road has a old Simplicity snowblower (5hp) & that thing would bust up the snowbanks w/o an issue.

He told me that it is because it has a Hydrostaic ****** & that it will not slip when into a snow bank as would a rubber disc snowblower.
I thought he was just set in his ways with old equipment & really just agreed with him. He then offered the machine to me to try out at my house once he was done. I could not believe that this old blower busted up the packed heavy ice/snow with no effort. I had it in 1st gear & it just would not stop.

Since then I was on the hunt for a snowblower with a Hydrostatic drive gear. They are over 1800.00 new because they are considered "Commercial Use".

I found a 1996 Simplicity 755 with a Hydrostatic Drivegear & a blown motor. I put a 8hp Tecumseh on it & got it going. Alll I can say is "WOW" this machine has so much torque it is amazing


Just wanted to let you all know that the older blowers with the Hyrdrostatic (PEERLESS 700 ******) are a true heavy duty unit worth restoring.

The best part is when in the garage/barn the mice will not be able to chew/eat the rubber clutch disc because it does not have one.

Total cost:

Snowblower: Free/ curbside
8hp Tecumseh $50.00
Misc/parts/ $30.00

Best $80.00 spent :rocker::rocker:

When I was a kid I worked on a wheel horse tractor that had one of the first hydrostatic drives in it. I think it used an Eaton hydraulic pump to run it. This was the same pump that was used on aircraft hanger doors and was designed to vary the output to permit full hp at very low flow rates, then move up to higher flow rates as the door started moving. These were a squash plate design that the angle of the plate determined the flow rate. They were over designed for a garden tractor and they went to something else very soon but the original were a marvel of over engineering.

Milton,

I was just blown away with the performance of the machine with hydrostatic drive. I will start looking around for them on craigslist/ yard sales.
Too bad so many have been left at the dump to be recycled. Thanks for the feedback.
