SOMECA 1580 (TD) or WHITE 4-150?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 1580 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4-150 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The WHITE 4-150 suits loader and hydraulic implement work better on this data: 36% (19.9 L/min / 5.3 gpm) more hydraulic flow.
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 4-150 has 36% more hydraulic flow (19.9 L/min / 5.3 gpm) than the SOMECA 1580 (TD) (both pump flow, as stated by the source).
- The SOMECA 1580 (TD) offers 540 rpm at the PTO, which the WHITE 4-150 does not (as stated by the sources).
- The SOMECA 1580 (TD) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 figures vary by configuration and the ranges overlap.
- 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 1580 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4-150 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 1580 (TD): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Someca 1580”); the 4-150: lift 610 mm behind the hitch ends, as stated by the source (Traktorenlexikon, “White 4-150”) — 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 and a creeper range.
