UTB U-640 (DTC) or WHITE 2-65?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the U-640 (DTC) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 2-65 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 WHITE 2-65 is 19% heavier (390 kg / 860 lb) than the UTB U-640 (DTC) (both unladen weight, as stated by the source).
- The WHITE 2-65 has 33% more forward gears (4 gears) than the UTB U-640 (DTC) (both forward gears, as stated by the source).
- Even on a creeper range: every machine offers one.
- 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 PTO speeds: the same speeds (540 rpm).
- 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 U-640 (DTC) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 2-65 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the U-640 (DTC): lift at the hitch ends, as stated by the source (Traktorenlexikon, “UTB U 640”); the 2-65: lift 610 mm behind the hitch ends, as stated by the source (Traktorenlexikon, “White 2-65”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass and PTO independence.
