4.6 Installing the Front Ballast Weights

The BELARUS-921.6 tractor without FMD can be equipped with the ballast weights
200 kg (10 pieces, 20 kg each).
While working with heavy mounted machines and implements in order to maintain
the tractor normal controllability under conditions of significant off-loading of the front axle
it is necessary to install additional ballast weights 1 (Figure 4.6.1). The ballast weights 1
are to be installed on the special bracket 6, which is fastened to the tractor front toolbar 5
and tightened together by string 4 and nut 7 through distance bushing 1.
1 – distance bushing; 2 – additional ballast weights; 3 – towing device;
5 – front toolbar; 6 – bracket; 7 – nut.
