OPERATING YOUR LAWNMOWER

W A R N I N G

The  unit’s  steering  control  levers  are  very  responsive:  For  smooth  operation,  move  lever

s

  slowly, 

avoid

ing

sudden  movement

s

.  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.

W A R N I N G

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.

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 

that

 specialize in sharpening mower blades. Blade sharpness should be checked daily.

D A N G E R

Never work with blades while key is in the ignition switch. Always place deck clutch switch in the 

disengaged position, place steering control levers in the park brake position and turn key to the OFF 

position  and  remove  key  from  switch.  Block  up  mower  when  you  must  work  under  it.  Wear  gloves 

when 

handling blades. Always check for blade damage if mower strikes a rock, branch

,

 or another foreign 

object 

during mowing!

Direct grass discharge to right,

 away from unmown area. Select a mowing pattern that directs grass 

discharge towards the outside

 the 

mowing area. Generally, this means using a pattern utilizing left turns 

because side discharge is to 

the 

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

 at first, 

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.

Charge the battery immediately. 

If battery percentage is higher than 

2% and less than 5%

,  the 

maximum drive speed will be 5 mph and the unit will in low blade mode. If battery percentage is less than 

2%

, the working blade will stop automatically.

 The unit should immediately be returned to the battery
