Deutz-Fahr AgroPrima 4.51 or ZETOR 8641 (2002-2007)?
Which should you choose?
On performance, every comparable figure that differs favours the ZETOR 8641 (2002-2007): hydraulic flow and three-point lift. It is also ahead on forward gears.
- The ZETOR 8641 (2002-2007) suits loader and hydraulic implement work better on this data: 24% (11.0 L/min / 2.9 gpm) more hydraulic flow and 49% (1,850 kg / 4,079 lb) more three-point lift.
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.
