More about the Allis-Chalmers 7040

The first Allis-Chalmers 7040 Tractors went out of the factory gates in 1975 and they kept building them until 1977. Sold initially at a price of $24,550, the Allis-Chalmers 7040 Tractor had a few price variations, so if you got it for less, you found a great deal! We have all the parts you need for your Allis-Chalmers 7040 Tractor to keep it running. Make sure you have access to your tractor serial number, because there is a chance that the Allis-Chalmers 7040 parts you need depend on that serial number. Usually, the serial number is printed above PTO shield. That serial number is determined by the year of manufacturing, so for a 1975 model, it starts with 1303, for a 1976 model it starts with 4089, for a 1977 model it starts with 6839. They also have differential hydraulic wet disc brakes. The type III/II 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540/1000 rpms. The Allis-Chalmers 7040 has a closed center hydraulics system with a 24.1 gal [91.2 L] capacity. The pump does the job pushing 22 gpm [83.3 lpm] fluids in the hydraulics system.
