Ford 1120 Tractor Operator's Manual
This Ford 1120 operators manual is the factory operation and maintenance reference for the Ford 1120 compact diesel tractor, 68 pages of controls, operating procedure, lubrication and scheduled maintenance. It's the book that came with the machine: the instrument panel and Proof-Meter, starting and break-in procedure, the 9-speed gear transmission and the optional hydrostatic drive, the rear and mid PTO, the hydraulic lift and manifold block, separate lubrication and maintenance charts for two-wheel and four-wheel drive, and the complete specification tables. Originally published by Ford New Holland and delivered here as an instant PDF download you can read on any device or print for the shop.
Models covered: Ford 1120 with the gear transmission or the optional hydrostatic transmission (H.S.T.), in two-wheel drive and four-wheel drive.
About the Ford 1120
The 1120 is the smallest of Ford's Twenty Compact Series, built in Japan by Shibaura from 1987 to 1993. It runs a three-cylinder diesel (the Shibaura S723) of 53.6 cu. in. (879 cc) on a square 2.83 × 2.83 in. bore and stroke, with a 23:1 compression ratio and a rated speed of 2500 rpm. The manual prints 12.5 observed PTO horsepower.
The standard gearbox gives three forward speeds and one reverse in each of three ranges, 9 forward and 3 reverse in all, with a top speed of 9.1 mph. The optional hydrostatic drive uses a rocker pedal and a two-range selector, reaching 3.7 mph in Low and 9.6 mph in High, with a speed control lever to hold a set forward speed. The rear PTO turns 540 rpm at 2385 engine rpm on the gear tractor and 2300 rpm on the hydrostatic. Brakes are expanding-shoe drums, steering is manual, and the live Category 1 three-point linkage is fed by a 4.7 gpm gear pump. With ROPS the gear tractor weighs 1338 lbs. in two-wheel drive form.
Full engine, capacity, hydraulic, tire, dimension and ground speed figures are listed on the Ford 1120 specifications page.
What This Ford 1120 Operators Manual Covers
- International symbols and safety precautions: The symbol key used on the tractor's controls, followed by the full safety section covering operation, servicing, driving, PTO work, diesel fuel and the ROPS.
- Controls and instruments: Seat, seat belt and ROPS, lighting, the instrument panel (key switch, gauges, warning lights and Proof-Meter), throttle and brake controls, the differential lock, the gearshift and range levers, the hydrostatic pedal, speed control and range selector, four-wheel drive and PTO levers, and the hydraulic lift controls including the flow control valve, remote valves and manifold block.
- Operation: Break-in procedure, starting (including jumper cable starts) and stopping the engine, operating the mechanical and hydrostatic transmissions, four-wheel drive and PTO, towing the tractor, the differential lock and the hydraulic lift system.
- Driving, tread settings and weighting: Driving technique, front and rear wheel tread settings, tractor weighting with cast-iron and liquid ballast, and the tire inflation and load table.
- Lubrication and maintenance charts: One chart for the two-wheel drive tractor and one for the four-wheel drive, with every service point against its interval.
- Fuel and lubricants: Fuel and lubricant specifications with the engine oil viscosity chart, then the service procedures for engine oil and filters, transmission and hydraulic oil, the H.S.T. oil filter, the fuel system and bleeding it, and the cooling system.
- General maintenance and tractor storage: Air cleaner, injectors, engine speed and valve clearance adjustments, battery and electrical, front wheel bearings, steering free-play, toe-in, brake and clutch adjustment, and how to store the tractor and return it to service.
- General torque specification table: A dedicated fastener torque reference.
- Specifications: Engine, capacities, cooling, electrical, fuel, clutch, brakes, steering, PTO, hydraulics, cast-iron weights, draw bar, tires, ROPS bolt torques, lubricants with Ford part numbers, dimensions and the ground speed chart.
- Safety and instruction decals: Decal locations, what each one says, and their part numbers for replacement.
- Pre-delivery and 50-hour service: The dealer check sheets, plus the owner assistance page.
Why This Manual Matters
- Both transmissions in one book. The 1120 came with a 9-speed gearbox or a two-range hydrostatic, and this manual covers the controls, operation, PTO speeds and weights for each.
- Two drivelines, two service charts. The two-wheel and four-wheel drive tractors each get a lubrication and maintenance chart, and the four-wheel drive front axle gets its own fill and capacity.
- Reference data you can set to. Valve clearances, belt deflection, clutch pedal free-travel, steering free-play, toe-in, the general torque table and full system capacities are all printed here.
- Decal identification with part numbers. The decal section shows where each decal belongs and gives its part number, which helps when restoring a tractor to original.
- Clean, restored scan. Scanned from an original manual, with punch holes, scanner marks and a previous owner's handwriting cleaned up, and the photos kept light enough to see what each figure is pointing at.
