Ford 4000 Tractor Troubleshooting
The
Ford 4000 is a two-wheel drive utility tractor. This model was manufactured from
1962 to 1975. The Ford 4000 is powered by Ford vertical 3-cylinder naturally
aspirated cooled diesel engine with a maximum power of 46.7 hp (34.8 kW), or
Ford 3-cylinder water cooled gasoline engine with a maximum power of 46.3 hp
(34.5 kW).
The Ford 4000 tractor was fitted with 2 types of transmission. 1st type:
8x2 Dual-Range transmission. 2nd type: Select-O-Speed transmission with
10 forward and 2 reverse gears.
Max. travel speed (forward/reverse): 17.6 mph (28.3 km/h) and 8.1 mph
(13 km/h). The open center hydraulic system used a gear pump with a
rated fluid flow of 5 gpm (18.9 lpm) or 5.5 gpm (20.8 lpm). The main
relief pressure is 173 bar (2500 psi). The tractor is equipped with
6.0x16 or 7.5x16 front tyres and 12.4x38 or 13.6x38 rear tyres. The
wheel base is 84.5" (2140 mm). The Ford 4000 is compatible with a
Ford
771 loader with lift capacity to full height of 1800 lbs (816 kg), or
Ford 772 loader with lift capacity to full height of 2500 lbs (1134 kg).
