John Deere 7700 (A) or Steyr 8170 a?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 7700 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 8170 a has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The John Deere 7700 (A) suits loader and hydraulic implement work better on this data: 133% (55.7 L/min / 14.7 gpm) more hydraulic flow.
- The John Deere 7700 (A) suits road haulage better on this data: 44% (3,500 kg / 7,716 lb) more maximum permissible mass.
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 John Deere 7700 (A) has 133% more hydraulic flow (55.7 L/min / 14.7 gpm) than the Steyr 8170a (both pump flow, as stated by the source).
- The John Deere 7700 (A) has 44% higher maximum permissible mass (3,500 kg / 7,716 lb) than the Steyr 8170a (both maximum permissible mass, as stated by the source).
- The John Deere 7700 (A) is newer: production began 12 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 top speed (both top speed forward, 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 PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 7700 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 8170 a has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the 7700 (A): lift at the hitch ends, as stated by the source (Traktorenlexikon, “John Deere 7700”); the 8170 a: lift at an unstated point, as stated by the source (Traktorenlexikon, “Steyr 8170”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power and a creeper range.
