[QUOTE="Romeogolf, post: 6768724, member: 60028"] Thankyou for your replies. The reasons are numerous really. Practically, the pump is heavy and awkward to fit, and on my tractor requires me to remove the pto guard which is a pain. Operationally, the pto pump takes forever to get the fan up to speed, which if one is impatient as I have been at times, can lead to blocked pipes very quickly. It also requires the engine revs to remain constant. It would be far more pleasant to let the hyd pump worry about constant pump pressure allowing me to drive the tractor as I would rather. Mechanically, the pto pump is leaking oil at quite a rate now, the last time drilling wheat it required constant topping up. I would rather not spend the money to repair it, instead get it converter to spool pump. I wonder if these motors vary, as I only have two pipes into my motor. The pipe coming from the bottom of the tank will connect to the T piece that goes into the top of the tank with no altering. Doing this would allow anything from the PRV, the excess from the variation valve, and the return from the pump to go straight into the Freeflow return on the tractor. I assumed that would complete all the circuits required. I have electric spools which can be set for constant pump down to 5% flow in either direction. I intended to start there and see how much of an increase was needed, and of course put it in float to let the motor spool down slowly. I don’t want to get this wrong! [/QUOTE]
