I bought an old Toro Reelmaster and got it running. 38 HP Puegot Diesel, 5 cutting reels. I want to use it to cut around the farm, But as I suspected, The reels don't cut the higher grass. I want to build a cutting deck to replace the reels in front. I would like to power the deck (or decks) with the existing hydraulic lines. -Has anyone ever tried this and can you give me some tips up front. I read that blade Rpm are around 3600. Is this about right. Where do you find Hyd. Motors for Cutting Decks. - Can you run the motor directly to the Mandrel or better with a pully setup
Thanks
The pump/pumps on the machine apparently has the volume to run those motors. Is that a single pump, or a series of three or four pumps. Those motors might be high speed, and low torque. Like this one below.

The pump would have to supply the same volume to all three hyd motors in a three motor deck. So if each motor needs, 8 GPM, then the pump would be rather large. What is the engine HP , from that, you can figure the max pump displacement. Never mind, I see the HP above at 38 HP.
Just an example.
This small high speed motor above will develop about 10 HP , and if turning a 32 in blade, it should work quite well. So if three hyd motors develop 30 HP, then that means that the pump has to develop more HP, maybe around 35 HP. The engine to pump loss is about 95 %, so the engine to power this setup, should be about 40 HP, allowing some HP for ground travel.
If you had only one hyd motor, then you would use the motor/pully belt setup. Since you have three motors, I would direct couple them using standard couplers.
There should be a relief valve across the motor to help with shock loads.
The motors appear to have a motor case drain line, and you don't wantany back pressure on it.
The drains usually go to sump/reservoir.
