Bührer GM-29 Super-Six (A) or Leyland 2100?

Which should you choose?

On performance, every comparable figure that differs favours the Leyland 2100: hydraulic flow and three-point lift. It is also ahead on top speed and PTO speeds. On features, the Bührer GM-29 Super-Six (A) is ahead on forward gears and drive.

  • The Leyland 2100 suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
  • The Leyland 2100 suits loader and hydraulic implement work better on this data: 121% (22.8 L/min / 6.0 gpm) more hydraulic flow and 12% (285 kg / 628 lb) more three-point lift.
  • The Leyland 2100 suits road haulage better on this data: 36% (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.
