BUKH 403 (Super) or International Harvester D-440?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 403 (Super) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-440 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester D-440 suits loader and hydraulic implement work better on this data: 50% (8.0 L/min / 2.1 gpm) more hydraulic flow and 82% (900 kg / 1,984 lb) more three-point lift.
- The BUKH 403 (Super) 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 International Harvester D-440 has 50% more hydraulic flow (8.0 L/min / 2.1 gpm) than the BUKH 403 (Super) (both pump flow, as stated by the source).
- The International Harvester D-440 has 82% more lift (900 kg / 1,984 lb) than the BUKH 403 (Super) (both lift at the hitch ends, as stated by the source).
- The BUKH 403 (Super) has 25% more top speed (5.0 km/h / 3.1 mph) than the International Harvester D-440 (both top speed forward, as stated by the source).
- The BUKH 403 (Super) offers 1000 rpm at the PTO, which the International Harvester D-440 does not (as stated by the sources).
- The BUKH 403 (Super) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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.
- Not comparable on power at the PTO shaft: the 403 (Super) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the D-440 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, maximum permissible mass, a creeper range and PTO independence.
