Ours was a factory kit for the Brent, and it still will NEVER outperform or outlast a PTO. If ya have to have hyd. then ya have to, but if there is a PTO even close to bein available leave the hyd for the slides and the auger folding.  We had two scv,s running the one motor, you could get speed but if ya opened your slide and let the grain flow the pressure on the hyd motor run up to operating pressure pretty quick with not alot of grain comin out the end! YUCK for us. Our cart serves 3 STS machines and I will be REALLY happy to  see that good old power take off at work! Good luck and have a safe and profitable day!
