Hermann Lanz D 634 or SOMECA 315?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 634 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 315 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Hermann Lanz D 634 suits road haulage better on this data: 17% (4.1 km/h / 2.5 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.

What does this mean in plain words?
- The Hermann Lanz D 634 is 16% heavier (240 kg / 529 lb) than the SOMECA 315 (both unladen weight, as stated by the source).
- The Hermann Lanz D 634 has 17% more top speed (4.1 km/h / 2.5 mph) than the SOMECA 315 (both top speed forward, as stated by the source).
- The Hermann Lanz D 634 is newer: production began 9 years later. We hold no parts-availability data, so there is no call on parts.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO independence: every PTO is independent.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the D 634 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 315 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, three-point lift, maximum permissible mass, a creeper range and PTO speeds.
