About the John Deere 8630

John Deere started producing the 8630 Tractor in 1975 and continued until 1978. Be sure to look for any serial number comments in the part fit notes. In some cases, the John Deere 8630 Tractor parts you need depend on your serial number. You can find the serial number on the back of transmission case. Serial numbers include 1000 from 1975 models, 2382 from 1976, 5222 from 1977, 7626 from 1978. They also have hydraulic wet disc brakes. The type III 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 1000 rpms. The John Deere 8630 has a closed center constant pressure hydraulics system with a 26 gal [98.4 L] capacity. The pump does the job pushing 33 gpm [124.9 lpm] fluids in the hydraulics system.
