J.I. Case 770 or Lamborghini R-603 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 770 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-603 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The J.I. Case 770 suits loader and hydraulic implement work better on this data: 228% (42.1 L/min / 11.1 gpm) more hydraulic flow.
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 J.I. Case 770 has 228% more hydraulic flow (42.1 L/min / 11.1 gpm) than the Lamborghini R-603 (DT) (both pump flow, as stated by the source).
- The J.I. Case 770 is 116% heavier (2,205 kg / 4,861 lb) than the Lamborghini R-603 (DT) (both unladen weight, as stated by the source).
- The J.I. Case 770 offers 1000 rpm at the PTO, which the Lamborghini R-603 (DT) does not (as stated by the sources).
- The Lamborghini R-603 (DT) is available with four-wheel drive; the J.I. Case 770 is two-wheel drive (as stated by the sources).
- 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.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the 770 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-603 (DT) 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 and PTO independence.
