Liquid Ballast; Tire Pressure - New Holland TC21D Operator's Manual

LIQUID BALLAST (OPTIONAL)
It is a common practice to add weight to the tractor by
filling the rear tires with liquid. A calcium chloride
(CaCl ) and water solution is recommended due to
2
its low freezing point and greater density (weight per
gallon) than pure water.
Never exceed the total recommended weight for the
tractor. Because special equipment is required to fill
the tires, consult your New Holland Dealer.

NOTE: Do not underinflate or overinflate tires. Do not exceed maximum inflation pressure listed.
SECTION 2 - OPERATION
Tires should never be filled beyond 75%. At 75% full,
the liquid will come to the valve stem when the valve
stem is at its highest point at the top of the wheel.

TIRE PRESSURE

Tire pressure must be considered when adding
weights, implements, or attachments to the tractor or
damage to the tractor may occur.
