Deutz-Fahr AgroStar 8.31 or Massey Ferguson MF 8170 A?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the AgroStar 8.31 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the MF 8170 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Massey Ferguson 8170A suits loader and hydraulic implement work better on this data: 36% (31.2 L/min / 8.2 gpm) more hydraulic flow.
- The Massey Ferguson 8170A suits road haulage better on this data: 29% (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.
