JD 4630 with synchro

Hope it is not like the 4630 my uncle bought , It was and 8 speed and it had a vary bad habit of just jumping out of gear . He bought it after the 4520 was stolen and along with it came the 6 x 18's and you would be running along in fifth plowing and all of a sudden she would jump out of gear and you would kiss the windshield along with getting some privet tender body parts hitting the steering wheel . then it blew the whole back rockshaft housing and sent the three point piston flying across the road hitting the new metal tater storage building and it looked like a 105 round went thru . They worked on it and worked on it and it still would jump out of gear . And it was a DOG , my accountant bought a power shift one and ya had to run it like a small block Chevy ya had to keep it buzzen or it would fall flat on it's face . I ran it one day discing with a 20 foot disc and ya had to have it running over 1500 RPM before you dropped the disc or it would plum up and die . Heck my old 806 with the same disc you can drop the disc then open it up and it just picks up and goes .
 
It was a DOG because the injection pump aneroid was set too tight. Injection pump/governor that has an aneroid have two fuel settings, a max fuel setting WITH turbo boost to the aneroid, and lower fuel setting with no boost to the aneroid to prevent acceleration smoke. When the aneroid no boost fuel screw is set too low, AND the diaphragm spring setting too high the engine WILL be a dead dog far as acceleration goes.
 
My experience with these larger older Deere tractors is that they can be very good value for the HP. Too old and small for a modern BTO, and too big for most hobby farmers (1000 only PTO).
