Ford 1200 Tractor Specifications

Specs Hub › Ford › 1200

Complete specifications for the Ford 1200 compact tractor, transcribed from the specifications section of the factory operator's manual (SE 3973, 1980). The 1200 was the four-wheel drive model in Ford's early Shibaura-built compact range, powered by a two-cylinder diesel of just 49.1 cu. in. producing 11.0 observed PTO horsepower. It is a small machine by any measure: 94.9 in. long, 42.7 in. wide, and 1288 lbs. bare. Every dimension, tire size and turning figure in this manual is given for four wheel drive, with no two wheel drive column printed anywhere in the section.

Notes:
1 The manual prints “asist”; spelling normalised.
2 Reproduced as printed. This line is internally inconsistent in two ways. 2.9 U.S. gpm is about 2.4 Imperial gallons per minute, not 3.3. And 127 bar is about 1849 psi, not 2133, which is also the figure the manual gives two lines below for the system relief valve. The 1849 psi and 127 bar pairing is self-consistent and matches the relief valve setting.
3 Reproduced as printed. 32° to 50°F is 0° to 10°C, not 8° to 10°C.
4 The manual presents ground speeds as a bar chart rather than a table. The values above are the endpoint figures printed on that chart at 1350 and 2700 rpm. They are transcribed, not measured from the graph.
All specifications transcribed from the specifications section of the Ford 1200 operator's manual, manual code SE 3973, originally published by Ford Tractor Operations, Ford Motor Company. Ford reserved the right to change specifications without notice; verify against your tractor's serial number before ordering parts or setting clearances.
