II. REAR END BALLASTING
a. WHEELS AND TYRES
Ballasting of rear wheel required for proper traction for heavy implements.
Ballasting can be done by water or cast iron weight. You can water ballast the Tyre
up to 75%. It is most convenient way of ballasting. For the normal atmosphere
region you can use ordinary water for ballasting. For tractors working in cole
climate precautions must be taken to avoid the water freezing.
b. PRINCIPLE
The type inner tubes on the driving wheels are fitted with air and water valves to
allow inflation with air and ballast with water. A special connections is required to
connect the water supply to the valve or filling with 75% water (Air + Water) the set
retains almost the same flexibility as when inflated with air only as the remaining
spaces filled with air at the pressure normally used for the load carried and the size
of tyre.
c. PROCESS OF WATER FILLING IN THE TYRE
Action:-
1. Jack up wheel & remove valve from the tube.
2. Deflate the tube.
3. Turn the wheel so that valve is on top/ 12 o' clock position.
4. Attach the hose to the valve body by till it details flowing back means of a special adopter.
5. Allow water to flow in.
6. Fill water up to upper rim level.
7. Take out the adopter and rotate the tyre to bring it to 11 o' clock position & replace the valve.
Allow water to flow out, and replace the valve. Bring in the tyre to 12 o'clock position again.
8. Fill in air to its normal working pressure of 10-12 psi.
9. Check the valve for proper tightness / leakage.
10. Remove the jack.
*While filling water in tube it is said that water should be filled up to upper rim level i.e. 75% of its
space, rest should be filled with air. Presence of air is necessary for cushioning effect and to
absorb shock.

6.3.2.2 USING CAST IRON WEIGHT (REAR)
Cast iron weight are available in a 34 kg size. Weight can be installed on the
outside of wheel. Use these weights as per recommendation. The tractor is
already supplied with one set of casting rear weight.
6.3.2.2.1 INSTALLING CAST IRON WEIGHT
Cast iron weight can be attached to wheel by means of bolt. One or two weight can
be attached. Tighten the bolts according to specified torque of 230 Nm.
NOTE: Ballast should be limited by either Tyre capacity or tractor capacity. Each Tyre has a recommended load carrying capacity,
which should not be exceeded. If a greater amount of weight is needed for traction then a larger. Tyre should be considered.
