Lamborghini R-1056 (DT) or VALMET 6600-4 (6600E)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R-1056 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 6600-4 (6600E) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The VALMET 6600-4 (6600E) suits loader and hydraulic implement work better on this data: 67% (32.3 L/min / 8.5 gpm) more hydraulic flow.
- The VALMET 6600-4 (6600E) 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 VALMET 6600-4 (6600E) has 67% more hydraulic flow (32.3 L/min / 8.5 gpm) than the Lamborghini R-1056 (DT) (both pump flow, as stated by the source).
- The VALMET 6600-4 (6600E) is 12% heavier (470 kg / 1,036 lb) than the Lamborghini R-1056 (DT) (both unladen weight, as stated by the source).
- The VALMET 6600-4 (6600E) has 20% more top speed (5.0 km/h / 3.1 mph) than the Lamborghini R-1056 (DT) (both top speed forward, as stated by the source).
- The VALMET 6600-4 (6600E) is newer: production began 14 years later. We hold no parts-availability data, so there is no call on parts.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the R-1056 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 6600-4 (6600E) 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 and a creeper range.
