Mower deck operation
Deck clutch operation
Clutch life will be maximized if these procedures are
followed.
1.
Engage the clutch
only when the throttle is set at
approximately
2/3 throttle
and there is
no load
on the
blades. After clutch engagement, advance the engine
throttle to full rpm.
Engaging the deck clutch at high engine rpm or when
under heavy load (in tall grass for example) can cause
belts and/or electric clutch to slip, resulting in premature
wear or possible damage.
2.
Disengage the clutch
only when the throttle is set at
less
than 1/2 throttle.
Never disengage the clutch with the engine running at
high rpm. Setting the throttle to less than 1/2 throttle
when disengaging the clutch will help extend clutch life.
Warranty will not be allowed
for deck clutches that fail due
to improper engagement and disengagement practices.
Deck cutting height adjustment
Deck cutting height is adjustable in 1/4” (.64cm) increments.
The holes in the height adjusting bar are spaced at 1/2” (1.27cm)
intervals. By turning the height adjusting stop around, 1/4”
(.64cm) increments can be attained due to the 1/4” (.64cm) plate
that is part of the stop. Figure 3-11
EXAMPLE:
When the height adjusting stop is placed in the
3” (7.62cm) hole,
with the
1/4” (
.64cm
)
plate facing to the
front of the unit,
the cutting height is at 3” (7.62cm). When the
height adjusting stop is placed in the 3” (7.62cm) hole,
with the
1/4” (
.64cm
)
plate on the operator’s side of the hole,
the
cutting height is at 3-1/4” (8.26cm).
The notch located at the rear
of the height adjusting bar
engages the stop handle when the deck lift pedal is fully
depressed. This sets the deck in
transport mode
.
Anti-scalp wheels
Anti-scalp wheel kits are standard on BigDog
®
Mowers.
These anti-scalp wheels are designed to minimize scalping
when mowing on rough uneven terrain.
After setting the cutting height, adjust the front anti-scalp
wheels so they extend below the deck but
do not contact the
ground.
They should always be at least 1/4” to 3/4” (6.35mm to
19.05mm) below the deck. With the unit sitting on a flat level
surface, the front wheel position can be adjusted up or down at
either 3/4” or 1-3/4” (19.05mm or 44.45mm) below the blade
surface. Move the front wheels up or down using the different
axle mount holes in the wheel mount bracket. Figure 3-12
NOTE:
When the anti-scalp wheels are installed, the mini-
mum cutting height is 1” (2.54 cm) with the anti-scalp wheels
set at 3/4” (1.91cm).
WARNING
Never direct discharge of material from mower deck
towards bystanders. Do not operate the mower without
either the discharge chute or the entire grass collection
system in place. Figure 3-10
Figure 3-10
DANGER
Never attempt to make any adjustments to the mower
deck while the engine is running or with the deck drive
clutch engaged. Mower blades cannot be seen and are
located very close to deck housing. Fingers and toes can
be cut off instantly.
