LIQUID BALLAST (OPTIONAL)
It is a common practice to add weight to the
tractor by filling rear tires with liquid. A calcium
chloride (CaCl
2
) and water solution is
recommended due to its low freezing point and
greater density (weight per volume) than pure
water.
Never exceed the total recommended weight for
the tractor. Because special equipment is
required to fill the tires, consult your SHIBAURA
Dealer.
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.
The chart below outlines tire inflation pressures.
FRONT TIRE INFLATION PRESSURES
Tire Type Tire Size Inflation Pressure
AG 8-16 140 – 240 kPa
AG 260/70R16 140 – 220 kPa
AG 9.5-16 140 – 215 kPa
TURF 27x10.5-15 120 – 210 kPa
REAR TIRE INFLATION PRESSURES
Tire Type Tire Size Inflation Pressure
AG 13.6-28 80 – 160 kPa
AG 380/70R28 80 – 140 kPa
AG 14.9-28 80 – 140 kPa
TURF 475/65D20 80 – 140 kPa
NOTE: Do not underinflate or overinflate tires. Do not exceed maximum inflation pressure listed.
