ZETOR 8641 or ZETOR 9641 (2002-2007)?
Which should you choose?
On performance, every comparable figure that differs favours the ZETOR 9641 (2002-2007): hydraulic flow and maximum permissible mass.
- The ZETOR 9641 (2002-2007) suits loader and hydraulic implement work better on this data: 22% (12.6 L/min / 3.3 gpm) more hydraulic flow.
- The ZETOR 9641 (2002-2007) suits road haulage better on this data: 13% (880 kg / 1,940 lb) more maximum permissible mass.
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.

What does this mean in plain words?
- The ZETOR 9641 (2002-2007) has 22% more hydraulic flow (12.6 L/min / 3.3 gpm) than the ZETOR 8641 (both pump flow, as stated by the source).
- The ZETOR 9641 (2002-2007) has 13% higher maximum permissible mass (880 kg / 1,940 lb) than the ZETOR 8641 (both maximum permissible mass, as stated by the source).
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- Even on three-point lift (both lift at the hitch ends, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power and a creeper range.
