The paper deals with possibility of reduction of tractor fuel consumption when working
on grass surface, and compares use of two
versions of spike devices embedded to the original tyre
body. The device was designed at Department Transport and Handling (Slovak University of
Agriculture in Nitra). Older as well as newer system proposed in 2017 comprises spikes and it is
assembled to
common tractor tyre tread pattern with auxiliary grooves cut in. Same device can
be set to two positions, allowing to work as 8
-
spikes and 16
-
spikes system. The spikes are tilted
in grooves when moving on paved road. The spikes are ejected out to reduce wh
eels slip when
operated in field. Remaining eight spikes are tilted in case of 8

type in tests with 3 different driving wheels, balanc
ing the actual weight in all cases. Drawbar
pull and fuel consumption were measured in tests, allowing to compute specific drawbar
consumption and fuel consumption per hour for three different loads. The results pointed out a
fact the tyre slip loss and en
ergy consumption of tractor movement increase at the soil humidity
19.45%. It follows from results achieved that use of both 8

and 16

spikes wheel device versions
reduced fuel consumption when cultivating higher humidity soil, preferable for tillage. Eigh

spikes system with semi

tilted remaining spikes is the most efficient method.
