Further according to the calculated loads, tire pressure shall be defined (in accord-
ance with subsection 3.2.8 “Selection of optimal inner pressure in tires depending on op-
erational conditions and load on tractor axles, instructions for use of tires”).
Tractor controllability criterion calculation:
T
1
- is load on the tractor front axle, N;
k
f
- is tractor controllability criterion;
M - is tractor operating weight (during calculation ballasts weights are not
taken into account in the tractor operating weight М), kg;
ATTENTION: COUPLING OF MACHINES TO THE TRACTOR SHOULD NOT RE-
SULT IN EXCESS OF PERMISSIBLE AXIAL LOADS AND LOADS ON TRACTOR TIRES!
ATTENTION: MINIMUM WEIGHT OF THE MACHINES ATTACHED, AND BAL-
LAST WEIGHTS USED SHALL ALWAYS MAKE NOT LESS THAN THE VALUES AT
WHICH LOAD ON THE TRACTOR FRONT WHEELS IN STRUCTURE OF MTU ALWAYS
MAKES NOT LESS THAN 20% OF THE TRACTOR OPERATING WEIGHT, AND THE
CONTROLLABILITY CRITERION MAKES NOT LESS THAN 0.2!
