Abstract

Experiment was conducted in one fields of Agricultural Sciences College in
Sulaymaniyah University with Silty-clay soil in order to study the effect of different
weights added to the rear wheels for agricultural tractor type New Holland 2WD,
with the effect of pressure bloating of rear wheels on the performance of triple
Mold Board in terms of some properties represented by: The amount of fuel
consumption, plowing practical speed, Slippage percent, soil penetration
resistance, covered soil volume, number of clods which have a diameter more
than 10 cm. Split- plot design used in this research under randomized complete
block design RCBD, where added weights factor on rear wheels wear put in the
main plots represented by two levels which are without weights and added
weights by 100 kg per each rear wheel, While bloating pressure factor of the
wheels has been developed in sub plots by three levels included 80, 100 and 120
Kpa. The results showed that the added weight had a significant effect on all
studded properties except of fuel consumed amount. While bloating pressure
factor of the wheels was significantly difference in the level 80 Kpa on 100 Kpa
level, which in turn significantly differs on the third level 120 Kpa in all studied
properties. As to the interaction between the factors, the weights 200 kg factor
with bulging pressure wheels 80Kpa recorded best significant effect on the rest of
interactions in all studded properties except in fuel consumed property which the
differences between the factors was In favor for the factor without weights with
the bulging pressure wheels 80 Kpa, as the results showed that there is no
significant differences between number of interactions for all studded properties
in the experiment except soil penetration resistance property, where was
significant differences between its levels.
