Hydraulic Pump Stand Alone ......12VDC or.........?

Hay_Man · Sep 1, 2012

I need a hydraulic pump to put in the back of our Kubota 1140 RTV. I want to be able to pull a hay rake with it and operate the cylinder that raises and lowers the wheels. Its a Vermeer 10 wheel rake. Has anyone here used such a set-up? I googled but was overwhelmed with results that didn't fit what I was thinking of.....

Thanks in advance for your suggestions.........

Many places sell the 12 volt powered hyd pumps. They are pricey at around $500 or more. Northern hyd sell them and as does a lot of other places.

The electric powered hyd unit on my J&I PU flat bed with Rd bale spikes built into it will do exactly what you desire. I've raised my H&S rake up to air up a low tire when it had popped off the rim. Also pulled tee posts with it.

Yep....that's what I need, but you're right about the price tag!

Wonder if I could build one out of a power steering pump, kinda like Lyle did to operate the hydraulics on his saw mill............with a small gas engine for the power.

An electric pump should be OK for an intermittent application like yours. The amperage draw will be pretty heavy, though.
Just be sure the controls on the pump match the type of use you have - single-acting vs. double acting cylinder, etc.

Something like this.......

A Chev power steering pump set up with some sort of motor or some how mounted to the engine in your rig will put out around 1500 psi and would do what you want but be slow. I used that type of set up on a Farmall B that I built a sickle mower to fit as a belly mount and used the pump and a cylinder to lift the bar

Hay_Man · Sep 1, 2012

Yep that was what I was wondering about. As in taking a long time to raise the wheels turning at the ends of the field.

I've had a Chevy power steering pump on my shop press for maybe 20 years and it's worked flawlessly, but as others said, it's slow. I brazed a 1" pipe fitting to the filler neck and ran a hose from the fitting to a supply tank to give it more oil storage capacity. I don't think you would be happy with it's speed but it would be reliable. Jim

Doesn't your rtv have bed tilt?

Hay_Man · Sep 1, 2012

Yep, It does have the hydraulic dump bed. I originally was planning to use those outlets, but I got concerned about contaminating the Kubota oil with John Deere oil for fear if the transmission developed problems I might not be able to get it repaired under warranty. What are your thoughts along those lines? Thanks for the reply.

Power steering pumps have priority flow dividers so that in the original application the flow at idle is close to the same as when the engine is sped up. That is so you have power steering at a standstill which is when you need it most. It is often possible to take them apart and figure out how those parts work so you can bypass or disable them. I once saw a 1953 Buick pump put out over 3000 PSI, but I don't know how long it would last doing that.

The oils shouldn't be an issue. That is to say I
wouldn't broadcast it if any wtty work arrises. You
can simply use those remotes. You'll probably have
to plumb your deere a little smaller though. I
think you'll be happy with the results.

Hay_Man · Sep 1, 2012

I was thinking of getting all the oil out of the cylinder that I could and trying it to see how it did. Maybe even flush Kubota oil through the hoses and cylinder first so there would be very minimum cross contamination. Should be OK like that.

I mounted a 12v pump unit on a low boy trailer one time to raise and lower the end gate. It worked great and wasn't any slower than the pto mounted pump that was on the road tractor. We bought it from Northern Hydraulics and it was around $270.00
We also mounted a switch at the tail end of the trailer where the hydraulic levers were and the switch ran a relay up on the pump. I believe we installed a 100 amp RV fuse in the circuit.

My 900 rtv has disconnects for the dump bed. I drag a snow groomer and the hyd. Work great

I wouldn't think the aux. hyd's would use the same
reservoir as the transmission. If it is the same,
see if the oil specs. are similar.

gene nehring · Sep 2, 2012

Good for you! SUDT isn't real cheap. Still don't
think you've got anything to worry about. The system
on your rtv is filtered too, so you've got extra
protection.

Hay_Man · Sep 2, 2012

What is SUDT? I pulled out the books on it and see that the 2 systems are separate. So I don't see a problem using the hydraulics on the RTV.

Thanks for the help everyone..........

Never mind, I found it. Its called UDT in my books. Trans. and Hyd, oil.

Thanks!
