Hydraulic motor specs

[Truckerdad]

Hello all..any know what the minimum reguirements/specs would be for a hydraulic motor that would be capable of powering a 38"(2 blade) or 48" (3 blade) mowing deck? Thanks

I believe the hyd motors on the Power-Tracs 48 in deck, are 3 cu in. If true, at 8 GPM's, the rpm will be 616, and the torque at 3000 psi will be 1433 in lbs.

I am not sure of the pulley ratio, but if known, you could work out blade tip speed.

OK thanks a bunch...it's a good place to start. Any and all info from any and everyone is appreciated!
