When adding weight, adhere to the maximum tire
capacity loading stated in the tables towards the end of
Chapter -5 of this manual. If further information or
assistance is required on tractor weighing consult your
Dealer.
When adding ballast, the total weight of the tractor
including liquid, cast iron weights and mounted
equipment (where specified) should not exceed the
maximum shown in the following text entitled 'Weighing
Limitations.
WARNING : If proper stability cannot be achieved
within the following weighing limitations, reduce the
load on the tractor until stability is restored
5.20 Weighing Limitations
For Agri applications –
Front Reaction – 1200 kgs Max.
Rear Reaction- 1500 kgs Max.
Total Tractor Reaction – 2500 kgs Max.
For Transportation purpose (includes Attachments and
Implements mounted on Tractor) Front Reaction- 1200
kgs Max.
Rear Reaction – 2000 kgs Max.
Total Tractor Reaction – 2900 kgs Max.
Front and Rear area can be independently ballasted to
max. recommended values ensuring total reaction is
within the recommended values.
Front loader refer below data.
5.21 Dampers
Damper is provided under the plat form for better
shock absorption.

Liquid Ballast
Filling the front and rear tires with liquid ballast is a
convenient method of adding weight. A solution of
water is recommended. This gives a low freezing point
and provides a higher density than plain water.
NOTE : When filling tires with water solution the valve
should be at the highest point on the wheel. If the tire
contains liquid ballast, the valve should be at the
lowest point when checking or adjusting air pressure.
Special equipment is required to water ballast tires.
See your Tractor Dealer or Tire Supplier for details.
Removal Procedure:
• Jack up the tractor & turn wheel to bring the valve
at bottom position.
• Remove the valve core housing and make
connections with pump.
• Completely evacuate the tire.
• Re-inate the tire with recommended air pressure.
5.22 How to do Wheel Ballasting
Ÿ Jack-up both rear wheels, remove valve body &
allow air to flow out completely.
Ÿ Position wheel nozzle @12'o clock location,
Ÿ Direct water jet into the tube & intermittently allow
internal air to flow out.
Ÿ Allow excess water to drain-out, that is above 11'o
clock location.
Ÿ Now rotate wheel & position nozzle at 12'o clock
location. Replace value body.
Ÿ Fill balance air pocket with 7-8 psi air pressure. DO
NOT fill higher pressure.
Ÿ Always position valve at 12'o clock to re-check air
pressure.
Do not fill 100% or over fill water, this will result in
SOLID wheel & will lead to rough ride & extra
slippage. Half filled wheel will not brake easily.
Ÿ For freezing cold regions add slat solution with
water to avoid freezing.
Do Not Fill more than 75% volume of tyre air space (upto Valve level)
Recommended AIR Pressure not to exceed 8 psi on near wheel
