Controls and Instrumentation
Entering the parameters to be programmed:
1. To display correctly the tractor motion speed, it is necessary to program in the speci-
fied order the following parameters:
Parameter “Z” is the number of teeth of the pinions of the final shafts of the driving
wheels (right and left), over which the (rotational) speed sensors are installed;
Select from the Table:
MTZ 590; 80.1; 890; 900;
922; 950
Parameter “I” is the multiplying factor of the gear rate of the wheel reduction gear;
Select from the Table
Gear ratio of the wheel reduction
gear (I)

Parameter “R”
R is the rear wheel rolling radius (mm);
Select from the Table
2. To display correctly the engine rotational speed, it is necessary to program in the spec-
ified order the gear ratio of the alternator drive (parameter “K”) from Table 8-6:
