About the John Deere 8440
In 1979, the very first John Deere 8440 Tractors went out. They were produced until 1982. You may have gotten a good deal and purchased your John Deere 8440 Tractor for less than the initial price of $64,000 (1982), but when it comes to spare parts for the John Deere 8440 Tractor, you will always get the best deal with us. Sometimes, the parts compatibility is determined by the serial number of your John Deere 8440 Tractor, and that info should be listed on the part fit notes. If you don't have the serial number of your tractor, you can find it on the rear of transmission case. The serial number starts from 1000 for a 1979 model, from 2266 for a 1980 model, from 3758 for a 1981 model, from 5235 for a 1982 model. They also have hydraulic wet disc brakes. The type III 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 8440 has a closed center hydraulics system with a 35 gal [132.5 L] capacity. The pump does the job pushing 33 gpm [124.9 lpm] fluids in the hydraulics system.
