Leyland 154 or SOMECA SOM-25 D/E?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 154 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-25 D/E has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Leyland 154 suits loader and hydraulic implement work better on this data: 93% (7.0 L/min / 1.8 gpm) more hydraulic flow.
- The Leyland 154 suits road haulage better on this data: 14% (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 Leyland 154 has 93% more hydraulic flow (7.0 L/min / 1.8 gpm) than the SOMECA SOM-25 D/E (both pump flow, as stated by the source).
- The SOMECA SOM-25 D/E is 11% heavier (118 kg / 260 lb) than the Leyland 154 (both unladen weight, as stated by the source).
- The Leyland 154 has 50% more forward gears (3 gears) than the SOMECA SOM-25 D/E (both forward gears, as stated by the source).
- The Leyland 154 has 14% more top speed (3.0 km/h / 1.9 mph) than the SOMECA SOM-25 D/E (both top speed forward, as stated by the source).
- The Leyland 154 is newer: production began 9 years later. We hold no parts-availability data, so there is no call on parts.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the 154 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-25 D/E 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, a creeper range and PTO independence.
