Hydraulically driven snowblower

Randyr · Jun 7, 2010

Has anyone here know of a snowblower that"s driven by hydraulics?
I was entertaining thoughts of a 3 point log splitter, but my hydraulic pump (MF35) is 4-5 gpm, so it would be too slow.
I could run it with a Prince pto pump, but what about a front mounted snow blower also, to get more use out of the pto pump?
Could it be run with a hydraulic motor?
Any one know what size of pump and motor would be needed?
I"m thinking of a 5"-6" dual stage blower.
Thanks.

Look to the bocat attachments - those skid steers with mega-flow hydraulics will run them.

Takes a big big $$$ pump.

Hyd driven blowers for skidloaders are available. Many need a high-flow pump, but my local Gehl dealer says you need to match the motor to the available flow, and my 4625SX can handle a blower for typical yard use if the motor is matched to the flow of the integral pump, without going to the Hi-Flow option, as long as it is not used for long-term commercial use. Front mount tractor blower with hyd drive- sure, but get ready to spend the $$$$$$$$$- custom made unit. Or front mount with pto drive from the rear- again, typically a custom mount like my local welder makes.

Lots of them are driven by hy systems when you find the one you want then you can get a [ump to tun it silly to get a pump then find out you should have got one bigger.Remember the pump takes HP.

The Prince pump would not be large enough to run much blower. You'd want something in the 40 gpm range for that which is probably a bit large for most people's taste on a wood splitter. Also a bit expensive.
The motor to run the blower would need to be of equal displacement (cubic inch) to the pump to maintain the correct speeds. You would also lose about 20% of the tractor's PTO power for the blower relative to a shaft drive. That's probably not something you want to give up on a MF 35...

All the skid steer blowers are hydraulic driven but are $4000+. If you want to cover the back tires of the tractor, a pto model would have a lot more HP available to it. Also for something like a blower that runs continuously, you're going to need a large hydraulic reservoir and most likely an oil cooler. It could be done but wouldn't be very economical. I tried a hyd. rototiller on my skid steer and it was not even close to comparing to a pto tiller. My skid steer and tractor are both around 40 HP. Dave

If you're into junkyard solutions, you might want to look at the hydraulic pump and motor off of an old Hesston or New Holland hydra-swing haybine. The pump will have plenty of flow, and the motor plenty of HP to run the blower.

Your Gehl dealer is correct. I built a snowblower for my ASV RC 30 rubber track loader. I used an old ford PTO snowblower, chopped off all the 3 point stuff, and used a hydraulic motor to chain drive the blower. The one thing I would tell you, though, is that theoretical specifications do not always translate into the real world. I would take the motor that you have chosen from the specs, and plug it into your system, and see how many rpms you are actually getting from the pump, with your tractor running at the range you normally run in. After you do this, then you can figure out the gearing ratio for your chain and sprockets. Surpluscenter.com has lots of pumps, motors, and gearing, plus they have all of the formulas you need to calculate. My creation cost me about $750, for motor, hoses, and gearing.

Sounds like this idea should go bye-bye.
