Finally serviced the 710 deck on the massey 8 today. Tried mowing with it and it seems to not be cutting the grass very well. I put new grease in the gear boxes, sharpened blades, installed new belts. It doesnt seem to be bogging down when its cutting. Idled up the engine a bit and it didnt make much difference. Doesnt seem to be throwing the grass very far. I timed the blades per the manual. The tractor is in the higher speed arrangement right now, so should i change it to the low speed arrangement and just go slower when I mow? Or did I miss something else? Please help!!!
