More about the John Deere 4040

John Deere started producing the 4040 Tractor in 1978 and continued until 1982. You may have gotten a good deal and purchased your John Deere 4040 Tractor for less than the initial price of $36,000 (1982), but when it comes to spare parts for the John Deere 4040 Tractor, you will always get the best deal with us. Make sure you have access to your tractor serial number, because there is a chance that the John Deere 4040 parts you need depend on that serial number. Usually, the serial number is printed on the rear of transmission. That serial number is determined by the year of manufacturing, so for a 1978 model, it starts with 1000, for a 1979 model it starts with 3199, for a 1980 model it starts with 6033, for a 1981 model it starts with 8707, for a 1982 model it starts with 11727. Some John Deere 4040 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 HFWD 4WD (optional) chassis, all equipped with hydrostatic power steering. They also have differential hydraulic wet disc brakes. The type II/I 3-point hitch is very reliable, capable to lift 4,316 lbs [1957 kg]. It is also worth noting that the independent rear PTO runs at 540/1000 (1.375) rpms. The John Deere 4040 has a closed center hydraulics system with a 11 gal [41.6 L] capacity. The pump does the job pushing 23 gpm [87.1 lpm] fluids in the hydraulics system.
