I have two 72" finishing mowers. One is a Farm King on the three point hitch of my 4410 and the other is an F-935 John Deere. I've made a few modifications to the Farm King to improve it. Extra anti scalping rollers underneath, change from side discharge to rear discharge, and change the crazy wheels to their newer, improved design. All of this has helped to let me mow at a faster speed. Now you would think that the 4410 with 35 engine horse power would whup the F-935 with only 22 engine horsepower, but the F-935 does a better job of mowing and at a faster speed than the Farm King. In tall 3'+ grass/weeds the Farm King can handle more residue because of more horsepower but cutting off 4" of lush new growth the F-935 wins by a wide margin. Hope this helps
