Operating suggestions

Prior to operating the mower the operator should be thor-
oughly familiar with the proper use and operation of the 
equipment, should read the manual completely and thor-
oughly, and should have attempted slow moving maneu-
vers to become familiar with the operation of the 
equipment before attempting normal speed operation. An 
inexperienced operator should not mow on slopes or on 
uneven terrain.

 

If you lose steering control while operating the 
machine, place the steering control levers in the park 
brake position immediately. Inspect the machine and 
involve your BigDog

®

 Mower dealer to resolve the 

problem before continuing to operate.

 

The unit’s steering control levers are very responsive: 

Easy does it! 

For smooth operation, move lever slowly, 

avoid sudden movement. Skill and ease of operation 
come with practice and experience.   The machine can 
spin very rapidly. Use caution when making turns and 
slow down before making sharp turns.

  

Inexperienced operators may have a tendency to oversteer and 

lose control. Slow-moving practice maneuvers are 
recommended to become familiar with these characteristics 
before attempting normal speed operation.

Sharp depressions or raised obstacles (such as gutters or 
curbs) should not be directly approached at high speed in 
an attempt to “jump” them as the operator could be 
thrown from the equipment. Approach at a slow speed 
and angle one drive wheel at the obstruction. Continue at 
an angle until the wheel clears and then pivot the opposite 
wheel around.

When turning on soft wet turf, keep both wheels rolling either 

forward or backward. Pivoting on one stopped wheel can 
damage turf. This is especially important when mowing.

Mower performance is maximum when the throttle is set at 

full rpm. This gives maximum power to the drive wheels and 
deck when needed. Use the control levers to control ground 
speed rather than engine rpm. 

Keep blades sharp.

 Many professional mowing companies 

have additional sets of blades and change blades twice a day: 

once in the morning and again at noon. 

Many problems

 with 

incorrect cutting patterns are 

due to dull blades

 or blades which 

have been 

sharpened incorrectly.

 Information on sharpening 

blades is listed in this manual’s maintenance section. In 
addition, most communities have individuals or companies 
which specialize in sharpening mower blades. 

Blade sharpness 

should be checked daily. 

Never work with blades while engine is running or deck 
clutch switch is engaged (on). Always place deck clutch 
switch in the 

disengaged

 position, place steering control 

levers in the park brake position and turn engine off and 
disconnect negative battery cable. Block up mower when 
you 

must

 work under it. Wear gloves when handling 

blades. A

lways check for blade damage

 if mower 

strikes rock, branch or other foreign object during mow-
ing!

  

Use high blade speed. 

Your mower is designed to operate at 

full throttle. The throttle setting directly controls blade speed. 
The highest blade speed generally gives best cut.

Direct grass discharge to right,

 away from unmown area. 

Select a mowing pattern that directs grass discharge towards the 
outside, not towards center, of mowing area. Generally, this 
means using a pattern utilizing 

left turns 

because side discharge 

is to

 right.

 In any case, avoid throwing grass discharge onto 

unmowed area because grass is then mowed “twice”. Mowing 
twice puts an unnecessary load on the unit and reduces mowing 
efficiency.

When mowing a lawn for the first time

 cut grass slightly 

longer than normal to avoid scalping uneven terrain. When 
possible, it is best to use the cutting height that was used in the 
past. When cutting grass taller than six inches, you may want to 
mow the lawn twice to achieve a better quality of cut.

During normal mowing cut only about 1/3 of the grass 

blade. 

Cutting more than that is not recommended unless grass 

is sparse or it is the end of the mowing season.

Alternate mowing direction 

to keep the grass growing 

straight and better dispersion of the clippings.

Remember, grass grows at different rates 

at different time 

of the year. Mow more often in the early spring to maintain the 
same cutting height. As the growth rate slows in mid summer, 
mow less frequently. If you cannot mow at a regular interval, 
mow at a high cutting height; then mow again two days later at a 
lower cutting height.

Raise the cutting height of the mower 

if the cutting width of 

the mower is wider than the previous mower. This ensures that 
uneven turf is not cut too short.

Raise the cutting height of the mower 

if the grass if slightly 

taller than normal or if it contains a high degree of moisture. 
Then mow it again with the cutting height set lower.

If the machine’s forward motion

 must be stopped while 

mowing, a clump of grass clippings may drop onto your lawn. 
To avoid this, move onto a previously cut area with the blades 
engaged.
