Allis Chalmers 7045 Tractor Parts

About the Allis-Chalmers 7045

The Allis-Chalmers 7045 was a larger 7000 Series tractor introduced in 1978. It used a 7.0-liter six-cylinder diesel, power steering, independent PTO, and a 20-speed or 12-speed partial power-shift transmission.

The 7045 remained in production through 1981 with a standard Acousta cab. It belongs to the same later 7000 Series group as the 7020 and 7060.
