About the John Deere 8640

In 1979, the very first John Deere 8640 Tractors went out. They were produced until 1982. Make sure you have access to your tractor serial number, because there is a chance that the John Deere 8640 parts you need depend on that serial number. Usually, the serial number is printed on the tractor transmission case, rear. That serial number is determined by the year of manufacturing, so for a 1979 model, it starts with 1500, for a 1980 model it starts with 3198, for a 1981 model it starts with 5704, for a 1982 model it starts with 7960. They also have hydraulic wet disc brakes. The type III,IIIN 3-point hitch is very reliable, capable to lift 8,545 lbs [3876 kg]. It is also worth noting that the independent rear PTO runs at 1000 rpms. The John Deere 8640 has a closed center hydraulics system with a 36 gal [136.3 L] capacity. The pump does the job pushing 33 gpm [124.9 lpm] fluids in the hydraulics system.
