The paper deals with a possibility of tractor slip reduction on a grass and evaluates an
use of two versions of special wheels. Both prototypes were developed at the Department of
Transport and Handling of the Slovak University of Agriculture in Nitra. The first system was
designed in 2010 year as blades wheels. The second system (spikes device) consists of spikes
which are mounted onto standard tractor tyres with special cuts, was designed in 2014 year. The
spikes are settled in these cuts while moving on road surface. The second one is placed near the
drive wheels and uses the blades. The spikes and blades are ejected to reduce wheels slip when
tractor operates on grass or soil. The base position allows tractor transport on road with standard
tyres. The goal of experiments realized on grass surface was to compare mutually slip behaviour
achieved. The measurements were realized with standard tyres without any modification, too. A
tractor with three types of drive wheels were loaded by heavier tractor. Drawbar pull and wheel
rotation speed for slip calculation were measured in tests. The results show a fact that a loss of
energy due to the wheels slip increases, while a penetrometric resistance in the surface layers of
a soil decreases, at soil humidity 33.2%. An application of both prototypes is very advantageous
because they reduce the wheels slip, increase tractor operation efficiency and so protect the soil.
