My one year old 3039R cab tractor (225 hours) vibrates with the newly purchased MX5. I use this tractor to mow 8-10 acres of grass weekly with a 6' finish mower with ZERO vibrations or troubles, in fact I sometimes forget the mower is running back there! I went to JD and bought a brand new MX5 cutter two weeks ago thursday, brought it home myself and put it on friday AM. The whole tractor vibrates, the steering wheel shakes an inch! Send it back to JD (they picked up) and said its fine, but we will replace the blades to see if it will resolve the issue. They delivered it back this morning, we hooked it to my tractor (they said they had ran it on a 3038e smoothly) and its even worse, the whole tractor vibrates! I sent it back of course, and said not to bring it back I was done with it. The salesman called and told me they cancelled the contract on it (luckily I opted to finance it!) and he was sorry. He then said the service dept had found a bulletin on the 3r cab tractors saying that they all vibrate with a 5' cutter behind them, regardless of the unit. SO, I typed all that to ask this, is he full of it or what? I need a bush hog, want to go buy one today on the way home (bush hog brand or titan 1500) but he said I better take the tractor as it will not work. WTF? I cannot imagine that this tractor cannot use a 5' cutter without shaking itself apart, it makes no sense. Every other PTO driven implement has no problems, my buddies 6' cutter is smooth but he says its ONLY with a 5'! Any words of wisdom? Really need to get some cutting done here, my old 5-1/2' bush hog is worn out but doesnt vibrate this bad! The stump jumper is bent on it and I cannot get it off so its getting replaced. Thanks in advance for any help you can provide! FYI I really do want a 5' cutter as I would like it tucked behind the tires so it wont catch small saplings and push the down the sides of the tractor.
