SOMECA SOM-30 B or ZETOR 3511/3545?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the SOM-30 B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 3511/3545 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The ZETOR 3511/3545 suits loader and hydraulic implement work better on this data: 21% (3.5 L/min / 0.9 gpm) more hydraulic flow and 11% (100 kg / 220 lb) more three-point lift.
- The ZETOR 3511/3545 suits road haulage better on this data: 25% (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.
