Now a couple questions for you. The deck needs 10 GPM. Remember flow is speed pressure is torque. What kind of pressure are they talking about in the literature? If I remember correctly that pump is 8 GPM. Also all pumps are rated on theoretical output. So your actual flow will probably be close to 6.5 GPM. Also running a hydraulic motor the oil will get very hot. Not good on that or any other pump. I would go with a separate pump & valve (with a motor spool)and at least a 10 gallon reservoir and run it off the crankshaft. Send me a phone number and we can discuss it in more detail

J, I just saw it on a website so I will have to call them for more information.
What you are saying makes sense and I don't think it would run off the Tractor's pump...I think a seperate pump is going to be the way to go if we go for this option. I would prefer not to use the PTO as I would like to be able to use this mower at the same time as I use the flail mower on the back. But if I had to I could do the fences after mowing the rest of the pasture.
J, after I dig for more info I'll give you a holler.
