5083e with a vibration toward rear end

There is a hill on my farm and when driving up it in c 1 i notice the vibration it feels like it is in the rear end the whole cab vibrates. But it only does it occasionally and i havnt notice it in any other lower gears. I was cutting hay today and the tractor would do it every now and then. Its kinda like the drive line on the haybine is out of balance but i no its not I have had it hooked to two different tractors with no problems. Could this be something with the hydraulic pump or some kind of valve for the drive clutches? I have not notice anything in reverse.

Could it possibly be the tires? Mine will vibrate at a particular speed under certain conditions on hard ground. I am pretty sure in my situation it is just the tires so I am not worried about it.

it could possible be that cause my tires are also loaded. but the deere service man is coming out to look at my loader the one other the pins that holds it on the holes are off bout 1/8 of an inch. It took a ratchet strap and a hammer and all 260 pounds to get the pin out. The other side pulls out and in very easy so I am thinking they are going to have to cut the welds and weld it back in place. Thank you for the possiblity tho I hope that that is the problem.
