HELA D 40 or J.I. Case Modell-VC?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 40 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Modell-VC has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The HELA D 40 suits road haulage better on this data: 21% (3.3 km/h / 2.1 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 J.I. Case Modell-VC is 39% heavier (546 kg / 1,204 lb) than the HELA D 40 (both unladen weight, as stated by the source).
- The HELA D 40 has 21% more top speed (3.3 km/h / 2.1 mph) than the J.I. Case Modell-VC (both top speed forward, as stated by the source).
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on drive: all two-wheel drive.
- 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 D 40 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Modell-VC 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.
