Small Hydraulic Cylinder

Buy new from Surplus Center. You're going to need more specs than that, though. You could get a flimsy little Bimba air cylinder rated at 75 psi with 1/4" ports and 4-6" of travel, and it damn sure won't work on your tractor. You need to know the max psi of the Kubota tractor system, and you need to know how much force you need to transmit with the cylinder.

Northern Tool (northerntool.com) has a variety of cylinders. I did a quick look and saw only 3/8 and 1/2' ports.

The snowblower my Dad has uses a small hydraulic motor, small sprocket on the motor with a chain wrapped around the chute, the chain simply rides in a "U" channel on the shoot with some little pins sticking out to hook the chain. Seems to work great, will spin all the way around if needed.

If you don't need something very rugged, Bimba makes some small inexpensive cylinders rated for hydraulic duty.

Bernie; Whenever you post a queston like this it is a good idea to give us an idea of where you are at. Makes pointing to a supplier easier. Just a thought. Regards. Ken.

Well ... the first guess eliminates southern Florida and southern Texas, given what he is modifying. :-)

His e-mail domain is cornell.edu, which suggests New York State. Near Ithaca, I think.

Enjoy, DoN.

Yeah, my dad bought a snowthrower without a remote chute director, he ended up using a chain sprocket that way. Just using a hydraulic cylinder would be quick, but I think positioning the chute accurately might be a problem. The O.P's going to want to go at least 180 degrees and just a straight linkage from the cylinder to the chute wouldn't let him do that. The O.P could use a cylinder driving a rack of some sort to move the chute, wouldn't be very compact, though. The hydraulic motor idea is probably best for this application, if there's no room up close for a sprocket and chain arrangement, how about a cable and drum? I've seen some manual chute mechanisms that use this, the cable is thin aircraft cable, it's wrapped around the chute's base and is wound back and forth by a drum. With proper jockey pulleys, the motor could be mounted in a convenient location, if needed. There would probably need to be some sort of stops so snow didn't get shot directly back at the operator.

Surplus Center in Lincoln, NE has a lot of different hydraulic motors, they're online at last,

Bailey Sales, or Northern Hydraulics?

Grant , Thanks for the input .I did get several responses to my question so will contact all .Yes as I am a class A tool maker and expermental Machinist i am well aware of pressure's on these things and once I find a supplier of what I am looking for then I will decide what I have and if it will work as well ,If neccesary I have the expertise of building one myself but am trying to eliminate that if I can buy one over the counter .

Thanks again. Bernie

I surely didn't mean to "look down my nose" at you, Bernie! There are a lot of guys who post questions to this NG who don't know as much as you. Good luck with your project, and I'm sure it will turn out great! - GWE
