HELA D 38 or Lanz D 6520/II?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 38 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 6520/II has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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 6520/II is 131% heavier (2,100 kg / 4,630 lb) than the HELA D 38 (both unladen weight, as stated by the source).
- The HELA D 38 has 67% more forward gears (2 gears) than the Lanz D 6520/II (both forward gears, as stated by the source).
- The HELA D 38 is newer: production began 7 years later. We hold no parts-availability data, so there is no call on parts.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the D 38 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D 6520/II 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.
