J.I. Case 1390 (DT) or Lamborghini R-654 (DT)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 1390 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-654 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The J.I. Case 1390 (DT) suits road haulage better on this data: 20% (5.0 km/h / 3.1 mph) more top speed.
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 1390 (DT) is 11% heavier (286 kg / 631 lb) than the Lamborghini R-654 (DT) (both unladen weight, as stated by the source).
- The J.I. Case 1390 (DT) has 20% more top speed (5.0 km/h / 3.1 mph) than the Lamborghini R-654 (DT) (both top speed forward, as stated by the source).
- The Lamborghini R-654 (DT) offers 1000 rpm at the PTO, which the J.I. Case 1390 (DT) does not (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 drive: every machine is available with four-wheel drive.
- 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 1390 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-654 (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, hydraulic flow, three-point lift, maximum permissible mass, a creeper range and PTO independence.
