Parasitic drag of hydraulic motor question

[ParkerFly]

Sounds more like a tractor pull sled to me. The axle pulls the weight forward during the run and the hydraulics pull it back to the start position.

That's exactly what it is. Some of the fancier setups use an air clutch to completely free the hydraulic motor from the driveline of the weight box, but I don't have that setup and have to put the motor in float. My concern with parasitic drag on the motor going up is that it will make the sled harder to pull. I don't imagine it could be all that much, but everything counts.
