Lanz D 9521 or RÖHR R 28?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 9521 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R 28 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The RÖHR R 28 suits road haulage better on this data: 18% (3.0 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.

What does this mean in plain words?
- The Lanz D 9521 is 126% heavier (2,150 kg / 4,740 lb) than the RÖHR R 28 (both unladen weight, as stated by the source).
- The Lanz D 9521 has 50% more forward gears (2 gears) than the RÖHR R 28 (both forward gears, as stated by the source).
- The RÖHR R 28 has 18% more top speed (3.0 km/h / 1.9 mph) than the Lanz D 9521 (both top speed forward, as stated by the source).
- The RÖHR R 28 is newer: production began 14 years later. We hold no parts-availability data, so there is no call on parts.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the D 9521 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R 28 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, PTO speeds and PTO independence.
