They could start there improvements on the hydraulics,#-1 the 3pt hitch leaks down and jumps back up while running indicating an internal leak of some kind. #2- I have an hyd. center link and it leaks out( while running) so fast it's almost useless.#3- the controls (hand levers and cables) for the 3rd & 4th scvs has to be about as cheap and worthless as Deere could find. #4- since I had the new axle installed(4600) I can't manuver forwards or reverse at low rpm it steers very hard, if I'm trying to drive into loader or back up to 3pt equipment it takes alot of forward and reverse attempts to get lined up. I know the small frames got bigger pumps & steering valves. #5- the female ends for loader hook up (hydralic) have all been replaced once because they leak after a while, running or not and I don't mean a drip now and then almost a steady strem. I am getting ready to replace two more. A swivel seat would be really nice, and a cab option on 4600 & 4700 would be nice. Fenders shake so bad at certain speeds(in feild and road) you think they're gonna fall off. budinohio.
