I have already purchased a 5''x24'' cyclinder,figured I needed the extra tonnage for the six way wedge.I'm going to try it first with the tractor hydraulics and if it looks like it's going to be to slow maybe I'll add a tank and pto pump like wk poors.I am kind of shying away from it because of the pricy pump cost.I love the way his is designed but mine is turned long ways instead of crossways already got it welded up.
