Lamborghini R 583 (DT) or VALMET 305 (305/4)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R 583 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 305 (305/4) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
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 VALMET 305 (305/4) has 42% more hydraulic flow (10.6 L/min / 2.8 gpm) than the Lamborghini R 583 (DT) (both pump flow, as stated by the source).
- The Lamborghini R 583 (DT) has 39% more lift (705 kg / 1,554 lb) than the VALMET 305 (305/4) (both lift at the hitch ends, as stated by the source).
- The VALMET 305 (305/4) is 38% heavier (740 kg / 1,631 lb) than the Lamborghini R 583 (DT) (both unladen weight, as stated by the source).
- 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.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on PTO independence: every PTO is independent.
- 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 R 583 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 305 (305/4) 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 and a creeper range.
