Renault 781 (S) or Renault 85-12 LS?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 781 (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 85-12 LS has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Renault 85-12 LS suits loader and hydraulic implement work better on this data: 30% (9.5 L/min / 2.5 gpm) more hydraulic flow.
- The Renault 85-12 LS 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 Renault 85-12 LS has 30% more hydraulic flow (9.5 L/min / 2.5 gpm) than the Renault 781 (S) (both pump flow, as stated by the source).
- The Renault 781 (S) is 13% heavier (405 kg / 893 lb) than the Renault 85-12 LS (both unladen weight, as stated by the source).
- The Renault 85-12 LS has 20% more top speed (5.0 km/h / 3.1 mph) than the Renault 781 (S) (both top speed forward, as stated by the source).
- The Renault 85-12 LS is newer: production began 8 years later. We hold no parts-availability data, so there is no call on parts.
- Even on three-point lift (both lift at the hitch ends, 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).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the 781 (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 85-12 LS 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.
