Porsche-Diesel Super N308 or Steyr 40, 40h, 40a?
Which should you choose?
On performance, every comparable figure that differs favours the Steyr 40, 40h, 40a: hydraulic flow. It is also ahead on forward gears, top speed and drive.
- The Steyr 40, 40h, 40a suits loader and hydraulic implement work better on this data: 53% (8.0 L/min / 2.1 gpm) more hydraulic flow.
- The Steyr 40, 40h, 40a suits heavy draft work (ploughing, cultivating) better on this data: 16% (255 kg / 562 lb) heavier and four-wheel drive.
- The Steyr 40, 40h, 40a suits road haulage better on this data: 40% (8.0 km/h / 5.0 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.
