I have 2 of these. They are the 'H Series' which are low speed, high torque. They need a decent flow of fluid through them. I have ran one with the Cub pump on my test stand. I uploaded the manual from Eaton for them here, page 55. I am looking for any thoughts/ideas on how to use them on our GT's or implements. They are not exactly the same and I think that is why the valve is between to even the speed of them.

Here is one of the motors.

They are quite heavy, around 11 lbs. Here are some of the specs for them.
 
Specifications
Gerotor Element         13 Displacements
Flow l/min [GPM]         57 [15] Continuous***
                                      76 [20] Intermittent**
Speed                          Up to 1100 RPM
Pressure bar [PSI]       125 [1800] Cont.***
                                      165 [2400] Inter.**
Torque Nm [lb-in]         407 [3604] Cont.***
                                       520 [4600] Inter.**

*** Continuous— (Cont.) Continuous rating, motor may be run continuously at these ratings.
** Intermittent— (Inter.) Intermittent operation, 10% of every minute.
 
 
Size is about 3.75" dia. by 5.5 long with a 4 bolt flange.
 
Until I can get a pump with more GPM set up, I am unsure what speed I can get from them. Hopefully, a pump is on the way here to fix that issue. (Thanks ducky). 
Member Alc sent me an inline flow meter, so I'll be able to set up properly to know what is going on.
 
I have thought of using one to make a lift system on an implement. For that, I thought to put a small sprocket on the motor and a larger one on a rock shaft for the implement. Gotta know the speed though and I am not sure that would work well.
So give me ideas folks.

Kenny does that valve spring center or just some kind of flow valve ?

It's just a flow valve. One way is closed, other open. Rather stiff to move, so should stay where you set it. Looks like it has about a 3/8" hole inside, though the ports are 1/2" NPT.

Roto tiller would work,running a winch, running a power broom. Any rotating device . Lifting a dump bed... not so good. Unless you use them to turn a screw type actuator.

Time to build a hydraulic driven dozer - one could power each track?  I wonder if they would run faster with a larger displacement hydraulic pump?

With the right set up, they can go 1100 RPM. Got some tracks you're not using?

No tracks unfortunately - wonder if you could make some out of some heavy duty roller chain??  Any snowmobiles down your way - you could use a couple of snowmobile tracks and drive them the same way they do on the snowmobiles - just a thought.

What's a snowmobile? LOL Nothing like that down here! Closest I could find would be a small trencher and they think those are gold plated!
