About the John Deere 2040

John Deere started producing the 2040 Tractor in 1979 and continued until 1981. Sometimes, the parts compatibility is determined by the serial number of your John Deere 2040 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 right side of the Deere 2040 frame, above the front axle. The serial number starts from 179963 for a 1976 model, from 221555 for a 1977 model, from 266057 for a 1978 model, from 304165 for a 1979 model, from 350000 for a 1980 model, from 392026 for a 1981 model, from 419145 for a 1982 model. Some John Deere 2040 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD chassis, all equipped with power steering. They also have hydraulic disc brakes. The type II 3-point hitch is very reliable, capable to lift 6768 lbs [3069 kg]. It is also worth noting that the independent rear PTO runs at 540 rpms. The John Deere 2040 has a closed center hydraulics system with a 14.5 gal [54.9 L] capacity. The pump does the job pushing 12.42 gpm [47.0 lpm] fluids in the hydraulics system.
