Fiat PRIMO 60-66 DT/Turbo or John Deere 2550 (A)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the PRIMO 60-66 DT/Turbo has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 2550 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The John Deere 2550 (A) suits loader and hydraulic implement work better on this data: 50% (16.4 L/min / 4.3 gpm) more hydraulic flow.
- The John Deere 2550 (A) suits road haulage better on this data: 14% (600 kg / 1,323 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.
