International Harvester 806 or Renault 951?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 806 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 951 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester 806 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The International Harvester 806 suits road haulage better on this data: 20% (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 806 has 20% more top speed (5.0 km/h / 3.1 mph) than the Renault 951 (both top speed forward, as stated by the source).
- The International Harvester 806 is available with four-wheel drive; the Renault 951 is two-wheel drive (as stated by the sources).
- The Renault 951 is newer: production began 10 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 figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Not comparable on power at the PTO shaft: the 806 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 951 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 and PTO independence.
