Demonstrating a Four-Wheel-Drive Tractor on the Buyer's Own Soil
Buyers should require a demonstration on their own field and soil, then use the tractor's speed range, transmission steps, hydraulic flow and drive control to set pass/fail checks for the trial and acceptance test.
A buyer specifying a four-wheel-drive tractor for agricultural work should make the demonstration run on their own field, with their own soil conditions, rather than accept a dealer-lot trial. Ask the supplier to work a representative strip at the shallowest and deepest tillage depths you expect, and to repeat the pass after rain or irrigation if your soil changes behaviour when wet.
Build the trial around the machine's stated capabilities. The operating speed range of 0.36–40 km/h and the 48 forward / 24 reverse speeds suggest checking whether the low-speed steps suit your slowest implement work and whether the reverse ratios allow practical headland turns. Ask how the electronically controlled four-wheel drive engages and disengages during turns, and confirm the conditions under which it should be left engaged. With hydraulic flow listed at 114 L/min, test your most demanding implement and record cycle times rather than relying on the figure alone.
Before requesting a quote, confirm with the supplier which tyres and ballast the demonstration tractor will carry, whether the trial unit matches the quoted configuration, who provides fuel and operator, and how the acceptance test will record speed, hydraulic performance and drive behaviour on your soil.
