Fendt Farmer 1 D or Hermann Lanz D 634?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Farmer 1 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 634 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Hermann Lanz D 634 suits loader and hydraulic implement work better on this data: 23% (350 kg / 772 lb) more three-point lift.
- The Hermann Lanz D 634 suits road haulage better on this data: 12% (3.1 km/h / 1.9 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.

- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the Farmer 1 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 634 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass and PTO speeds.
