BOLINDER-MUNKTELL 425 Terrier or Fahr D 135 H?
Which should you choose?
On performance, every comparable figure that differs favours the Fahr D 135 H: three-point lift. It is also ahead on forward gears. On features, the BOLINDER-MUNKTELL 425 Terrier is ahead on top speed.
- The Fahr D 135 H suits loader and hydraulic implement work better on this data: 38% (300 kg / 661 lb) more three-point lift.
- The BOLINDER-MUNKTELL 425 Terrier suits road haulage better on this data: 50% (10.0 km/h / 6.2 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.
