Ford 1620 Tractor Operator's Manual
This Ford 1620 operators manual is the factory operation and maintenance reference for the Ford 1620 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 three-range hydrostatic drive and its speed control lever, 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 1620 with the three-range hydrostatic transmission, in two-wheel drive and four-wheel drive.
About the Ford 1620
The 1620 is a compact Ford tractor built in Japan by Shibaura from 1992 to 1995 as part of Ford's Twenty Compact Series, slotting between the 1520 and the 1720. It runs a three-cylinder diesel (the Shibaura J843) of 81.16 cu. in. (1330 cc) on a 3.31 × 3.15 in. bore and stroke, with a 23:1 compression ratio and a rated speed of 2600 rpm. The manual prints 23.0 observed PTO horsepower.
Where most of the Twenty series came with a gearbox and a hydrostatic option, the 1620 manual is written around a hydrostatic drive. A rocker pedal controls speed and direction, a range selector gives Low, Middle and High, and top speed in High is 13.4 mph forward and 9.4 mph in reverse. A speed control lever holds a set forward speed. The rear PTO turns 540 rpm at 2465 engine rpm, and the optional 2000 rpm mid PTO is set at 2420 rpm. Brakes are wet disc, steering is full hydraulic power, and the live Category 1 three-point linkage is fed by a gear pump rated 6.87 U.S. gpm at 2133 psi. With ROPS the tractor weighs 2260 lbs. in two-wheel drive form.
Full engine, capacity, hydraulic, tire, torque, dimension and ground speed figures are listed on the Ford 1620 specifications page.
What This Ford 1620 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, fuel and temperature gauges, warning lights and Proof-Meter), throttle and brake controls, the differential lock, hydrostatic transmission controls, four-wheel drive and PTO levers, and the hydraulic lift system 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 transmission, 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 tire pressures.
- 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, the transmission and hydraulic oil, the fuel system and the cooling system.
- General maintenance and tractor storage: Adjustments and routine maintenance across the machine, and how to put the tractor away 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 bars, tires, wheel and 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 and both record copies, plus the owner assistance page.
Why This Manual Matters
- Written for the hydrostatic drive. The rocker pedal, the three ranges, the speed control lever and the ground speed chart all match the transmission the 1620 actually has, so you are not sorting through gearbox instructions that don't apply.
- 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, toe-in, wheel bolt torques, 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 and scanner marks cleaned up and the photos kept readable, so you can see what each figure is pointing at.
