ALLIS-CHALMERS 190 XT or Renault 851 (S)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 190 XT has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 851 (S) 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 ALLIS-CHALMERS 190 XT has 35% more hydraulic flow (11.7 L/min / 3.1 gpm) than the Renault 851 (S) (both pump flow, as stated by the source).
- The Renault 851 (S) has 69% more lift (1,520 kg / 3,351 lb) than the ALLIS-CHALMERS 190 XT (both lift at the hitch ends, as stated by the source).
- The ALLIS-CHALMERS 190 XT is 15% heavier (462 kg / 1,019 lb) than the Renault 851 (S) (both unladen weight, as stated by the source).
- The Renault 851 (S) has 50% more forward gears (4 gears) than the ALLIS-CHALMERS 190 XT (both forward gears, as stated by the source).
- The Renault 851 (S) is newer: production began 9 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 PTO speeds: the same speeds (540, 1000 rpm).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the 190 XT has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 851 (S) 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.
