John Deere 2950 (A) or Renault 851 (S)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 2950 (A) 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.
- The John Deere 2950 (A) suits loader and hydraulic implement work better on this data: 158% (53.4 L/min / 14.1 gpm) more hydraulic flow.
- The John Deere 2950 (A) suits heavy draft work (ploughing, cultivating) better on this data: 37% (1,112 kg / 2,452 lb) heavier and four-wheel drive.
- The John Deere 2950 (A) 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.

- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Not comparable on power at the PTO shaft: the 2950 (A) 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, three-point lift, maximum permissible mass, a creeper range, PTO speeds and PTO independence.
