Purpose: Modern and advanced mountain tractor allows four different modes of steering wheels: front wheels, back wheels, four wheels and crab steering. The current paper presents the impact of different ways of steering to control the slip in the work transverse on the steep hill slope (39.08%). Design/methodology/approach: For each mode of steering eight measurements were made; four measurements at a forecasted speed of 0.69 m/s and four measurements at a speed of 1.39 m/s. During the two of four measurements the travelling direction was from the left to the right, and vice versa. Findings: The measured slip depended significantly on the steering system, while the driving direction did not cause any differences in the slip. Research limitations/implications: The experiment results presented herein can be applied only with the similar mountain tractors, which allows four different modes of steering wheels. Additional limitation represents the working polygon and the growing conditions of grass. Practical implications: The crab - steering resulted in the smallest slip (5.96%) at the average driving speed of 1.08 m/s. When steering with all four wheels, the slip at the average speed of 1.03 m/s increased to 7.27%. The biggest slip was measured when steering with only front wheels was applied. In this case the slip was 8.07% at the average speed of 1.01 m/s. Originality/value: The findings from our experiments indicated that it is very useful to have all wheels steering tractor when working on step slope, because it is grass friendly, offers bigger agility of tractor and improve the safety of the operator.
