Case-IH Magnum 7120 or John Deere 4840?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Magnum 7120 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4840 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Case-IH Magnum 7120 suits loader and hydraulic implement work better on this data: 24% (20.9 L/min / 5.5 gpm) more hydraulic flow and 77% (2,888 kg / 6,367 lb) more three-point lift.
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.
