high moisture content. This build-up will harden, restricting
blade and air movement and will probably show a poorer quality
of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck
using jack stands or blocks, in the full up position and scrape the
build-up from underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled personnel.
Consult your BigDog
® Mowers service center when assistance
is needed.
Torque values
Particular attention must be given to tightening the drive
wheel lug nuts and blade spindle bolts. Failure to cor-
rectly torque these items may result in the loss of a wheel
or blade, which can cause serious damage or personal
injury.
Torque values are given below:
Ft-lbs. Nm
Wheel (lug) nuts . . . . . . . . . . . . . . . . 65-75 . . . .88.14-101.7
Blade spindle bolt top . . . . . . . . . . . . 65-75 . . . .88.14-101.7
Blade spindle bolt bottom . . . . . . . . . . 118 . . . . . . .160.01
Lug nuts only - It is recommended that these be checked after
the first 2 hours of operation, initially, every 50 hours and
following removal for repair or replacement.
For all other torques refer to the mower’s General Service
Manual for standard torque chart. See Product Literature
section for ordering information.
For engine torque values, see engine owner’s manual.
Tires
It is important for level mowing that the tires have the same
amount of air pressure. The recommended pressure are:
Drive wheels . . . . . . . . . . . . . . . . . . . . . 8-12 psi (55-83 KPa)
Gauge wheels . . . . . . . . . . . . . . . . . . . . 8-12 psi (55-83 KPa)
Only pneumatic tires are approved for BigDog ® Mowers
turf equipment. Warranty claims will be denied on any mower
equipped with non-pneumatic tires.
Lubrication
Use SAE multi-purpose grease.
Electrical system
The electrical system is a 12 volt, negative ground.
Recommended battery size is a garden tractor BCI group U1R
with 225 or better cranking AMP rating. A maintenance-free
battery is recommended. Otherwise, follow battery
manufacturer’s maintenance, safety, storing and charging
specifications.
Battery posts, terminals, and related accessories contain
lead and lead compounds, chemicals known to the State
of California to cause cancer and reproductive harm.
Wash hands after handling.
Charge batteries in an open well ventilated area, away
from sparks and flames. Unplug charger before connect-
ing or disconnecting from battery. Wear protective cloth-
ing and use insulated tools.
• Avoid skin and clothing contact with battery acid.
• Always wear eye protection when checking the bat-
tery, acid can cause serious injury to skin and eyes.
If contact occurs, flush area with clean water and
call physician immediately. Acid will also damage
clothing.
• Do not drink the battery electrolyte.
• Do not allow open flame near the battery when
charging.
• Hydrogen gas forms inside the battery. This gas is
both toxic and flammable and may cause an explo-
sion if exposed to flame. Always remove the nega-
tive ground first and replace it last.
• Do not overfill battery.
• Electrolyte may overflow and damage paint, wiring
or structure. When cleaning the battery, use soap
and water. Be careful not to get soap and water into
the battery. Clean the battery terminals with a solu-
tion of four parts water and one part baking soda
when they become corroded.
Shorts caused by battery terminals or metal tools touch-
ing metal mower components can cause sparks. Sparks
can cause a battery gas explosion which will result in per-
sonal injury.
• Prevent the battery terminals from touching any
metal mower parts when removing or installing the
battery.
• Do not allow metal tools to short between the bat-
tery terminals and metal mower parts.
