Rated speed is 2,300 rpm. The machine is 3,680 mm long, 1,890 mm wide and 2,473 mm high. The unladen weight is 2,515 kg. The wheelbase measures 2,143 mm. Ground clearance is 440 mm. Top speed is 30 km/h. The tank holds 73 litres. Transmission: 13V/4R. The engine is water-cooled. Tyres: front 6.50-20 ( A: 10.5-20 ), rear 13.6/12-36. The fuel is diesel. The bore measures 105 mm. The stroke is 120 mm. Maximum torque is reached at 1,400 rpm. Construction: unit construction (no separate frame). Injection pressure is 180 bar. The linkage is category II. The PTO runs at 540/1000 rpm. Around 587 ( A: 286 ) units were built. The Farmer 100er-Reihe series covers 13 models. Rated output within it ranges from 42 to 75 hp; the Farmer 104 LS/LSA sits in the lower part of that range with 55 hp. Its immediate neighbours are the Farmer 104 S/SA below it with 54 hp and the Farmer 103 LS/LSA above it with 56 hp. Unladen weight within it ranges from 2,215 to 3,110 kg; here the Farmer 104 LS/LSA sits in the lower part of that range with 2,515 kg. 1545 Fendt models across 89 series are on record.

Fendt Farmer 100 Series – Mid-Range of the 1970s and 1980s: three- and four-cylinder diesels with 31 to 55 kW (48 to 75 hp), 2,550 to 4,154 cm³ displacement, air- or water-cooled

The Farmer 100 series formed Fendt's mid-range class between compact and large models from 1970 to 1987. Output of the recorded models ranges from 31 to 55 kW, with models rated in horsepower spanning 48 to 75 hp, using three- and four-cylinder engines with displacement from 2,550 to 4,154 cm³.

Recorded operating weight runs from 2,215 to 3,110 kg, wheelbase from 2,062 to 2,247 mm, and top speed of the listed models spans 25 to 30 km/h. The S and LS suffixes in model names distinguished standard from luxury versions with a more extensive cab.

The Farmer 100 series targeted medium arable and mixed farms and competed at the time with comparable models from Deutz and John Deere. For a used model, check the cab version, as simple open platforms and enclosed LS cabs were offered in parallel.

Within the Farmer 100 series, individual models offered a choice of air or water cooling; water-cooled engines usually reach higher continuous output at the same displacement and tolerate turbocharging better, but require a radiator, water pump, thermostat and regularly changed coolant with frost protection. The PTO in this power class usually ran two-speed at 540 and 1,000 rpm, and the three-point hitch matched category I under ISO 730. When sourcing cooling-system parts on the used market, matching mounts and hoses need attention, as these are not identical between the two versions.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
  • Check the weights in the papers against the figures here — attachments change them.
  • Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
  • Shift the gearbox cold and warm — jumps only show up at temperature.
  • Load the hydraulics and watch for sag.
  • Ask about parts availability for this build year — the running costs hang on it.
