Fiat 615 (DT) or UTB U 650/651?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 615 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the U 650/651 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The UTB U 650/651 suits loader and hydraulic implement work better on this data: 51% (13.5 L/min / 3.6 gpm) more hydraulic flow.
- The UTB U 650/651 suits road haulage better on this data: 13% (3.0 km/h / 1.9 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 UTB U 650/651 has 51% more hydraulic flow (13.5 L/min / 3.6 gpm) than the Fiat 615 (DT) (both pump flow, as stated by the source).
- The UTB U 650/651 is 12% heavier (330 kg / 728 lb) than the Fiat 615 (DT) (both unladen weight, as stated by the source).
- The UTB U 650/651 has 13% more top speed (3.0 km/h / 1.9 mph) than the Fiat 615 (DT) (both top speed forward, 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 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 615 (DT) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the U 650/651 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 615 (DT): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Fiat 615/615 DT”); the U 650/651: lift at an unstated point, as stated by the source (Traktorenlexikon, “UTB U 650”) — 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, maximum permissible mass, a creeper range and PTO independence.
