Hydraulic Motor for Snowblower Chute?

I recently purchased a 3 point snowblower that has a manually rotated chute. The chute has cable wrapped around it that in turn wraps around a rod with an offset handle - crank the handle one way or the other and the cable winds up rotating the chute. Really a nice cheap setup that has a lot of allowance for misalignment.

To convert this to hydraulic rotate my thought was to remove the extension with the offset handle, build a bracket, and attach some type of low speed hydraulic motor to the end of the shaft via a flexible coupler. This would only require one bracket, one motor, and two hoses.

Has anyone attempted this before? Anywhere good to look for low speed hydraulic motors? Northern has new ones for around $200 - didn't know if certain implements that I could find in junkyards might have something that I could get cheaper. Any ideas greatly appreciated. Thanks.
 
You might try a hyd orbit motor from an irrigation wheel line mover. They turn slow and if not slow enough install a restrictor in hyd hoses.
 
Some blowers are turned with an orbit motor that has a small sprocket on it, which engages roller chain welded around the spout. A restrictor is needed to control speed so you can stop rotation in time.

Here"s my hyd adaptation, using a two-way cyl and brackets. Cyl mount is adjustable for proper throw of the spout. Cyl could mount directly to spout if you did the math/geometry first, and correct. Yup, channel iron bar bent when I didn"t lube the spout first! I just toss a bit of diesel fuel into the spout to lube it.....now.

I used a hydraulic motor off a Deere grain
head. Mounted it solid and left the
sprocket on it. Ran #40 roller chain around
the chute, welded a tab to the chute and
wired the chain to the tab with baler wire.
Works great.if the chute binds up, it
breaks the wire.not something else. Then
you just rewire it on and good to go! Also
put a hydraulic cylinder on the deflector

Maybe salvage the electric or hydraulic spout control off a scrapped forage harvester? A reel drive motor off a combine bean head might also work if it can reverse (use a flow control to limit the speed).
 
Bean head motor is a big advantage cuz it normally runs slower than the little orbit motors. Easy to slow down even more.
