Hermann Lanz D 634 L or Schlüter Super 350 / 350 V?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 634 L has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 350 / 350 V has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Schlüter Super 350 / 350 V suits heavy draft work (ploughing, cultivating) better on this data: 21% (365 kg / 805 lb) heavier and four-wheel drive.
- The Hermann Lanz D 634 L suits road haulage better on this data: 25% (5.0 km/h / 3.1 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 Schlüter Super 350 / 350 V is 21% heavier (365 kg / 805 lb) than the Hermann Lanz D 634 L (both unladen weight, as stated by the source).
- The Hermann Lanz D 634 L has 25% more top speed (5.0 km/h / 3.1 mph) than the Schlüter Super 350 / 350 V (both top speed forward, as stated by the source).
- The Schlüter Super 350 / 350 V is available with four-wheel drive; the Hermann Lanz D 634 L is two-wheel drive (as stated by the sources).
- The Hermann Lanz D 634 L is newer: production began 10 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 a creeper range: every machine offers one.
- Not comparable on power at the PTO shaft: the D 634 L has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 350 / 350 V has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
