Lamborghini R 684 (DT) or VALMET 455/445-4?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R 684 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 455/445-4 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Lamborghini R 684 (DT) suits loader and hydraulic implement work better on this data: 14% (360 kg / 794 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.

What does this mean in plain words?
- The Lamborghini R 684 (DT) has 14% more lift (360 kg / 794 lb) than the VALMET 455/445-4 (both lift at the hitch ends, as stated by the source).
- The Lamborghini R 684 (DT) offers 1000 rpm at the PTO, which the VALMET 455/445-4 does not (as stated by the sources).
- The VALMET 455/445-4 is newer: production began 7 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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 difference is under the 10% threshold, too small to call.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the R 684 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 455/445-4 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, maximum permissible mass, a creeper range and PTO independence.
