Its not that I need a variable speed. I need a constant speed. Your forgetting your reel on the 72 is always spinning regardless if the combine is moving forward or not.
On the 60/66, the tires drive the reel. If your combine is not going forward, your reel is not spinning.. I hate that.. and is fixed on the 72/90

If it says .98 gpm for 1000 rpm, that is exactly what it needs for 1000 rpm. |
Well then this motor should work dandy with a low flow pump like the 3GPM Allis because I would never need to go that fast. 50-100 RPM max

Tom, Read Kev's post again. The pump he is talking about works off of the combines PTO shaft. Your tractor turns the combine PTO shaft, so everything works powered by one tractor. |
Yes I see that. Sounds like it would have to be a proprietary get up wouldnt it? To run on the machines PTO as opposed to the end of the tractors PTO it would have to be in-line or use some sort of contraption that rides the shaft?. And this is a pump he's talking about. Dont want the pump expense if I can avoid it.

In most hydraulic motors, you get speed with volume and the resulting pressure comes from that speed doing work, e.g. producing torque. So speed and torque means horsepower, maximum speed and maximum torque means maximum horsepower.
When shopping for a motor, watch out for its maximum pressure rating the WD45's peak pressure of 3000 psi can blow the seals out of many motors.

Gerald, on the one I linked, max is 5000 PSI..also says .98 GPM at 1000 RPM.
Does that mean it needs a flow to it at .98 to get the thing to spin at 1000 RPM?..not sure how I am supposed to interpret that....

Will do but I dont have much hope....Read that the Wd45 has GPM of 3 or so....not promising... |
Well wouldya look at this:

I dont see how this wouldnt work. The machines PTO shaft would be spinning when you are using it, no?

Cant use a PTO pump. Dont need the added expense, and the combine wouldnt be able to do much without a PTO hookup available. Since the remote is powering the lift cylinder, I would want to tie in to the tractor lift rams line. So I need to find a motor that would work. Less than 1 HP required. Dont know the GPM of the WD45 pump...

First, you need to now how much HP the motor needs to do the work you want it to do...
You also need to know the GPM ( Gallons Per Minute) the motor needs and YOUR pump must be able to supply more than that for it to work.
You also need a good(big) reservoir for the oil(with baffles !) and large hoses and couplers.
The WD45 system is high pressure-low volume so I don't think you're in luck(others will KNOW)..I'd think about a PTO driven pump or one piggybacked onto the alternator/generator.It'll depend on the specs though....

Ok thanks. I do know that I need very little. I can spin the reel manually with my finger with no effort. The only resistance is going to be the crop which is not going to much - only a 5' cut. Slow speed as well; under 100 rpm I would think.

guys,
Look at this product:
Says to "avoid using maximum speed and pressure at the same time"...
I would think that to get max speed you need to apply max pressure..but since I know nothing about hydraulic motors, could someone educate me?
I would like to perhaps use this motor to power an all-crop reel independent of the ground travel. Would like to use my WD45 hydraulics system. Wondering what issues I have to deal with. One is the high pressures of wd45 hydraulics, two, want to still use the remote to lift the combine header--not sure if a conflict there...
