Mowing Speed
The design of the VERSA-PRO Z-Mower is to operate most efficiently at the maximum Blade speed. The
speed of the machine should allow the Mower Blades to maintain this maximum speed while mowing
across turf. Slow the machine for cutting tall grass, grass heavy with moisture, or when mowing on rough
terrain. If the ground speed is too fast, or the Blade speed is too slow, the Mower Blades will not be able to
lift the grass into the cutting position as the Mower passes over the ground, causing the mowing to be
uneven. You should adjust the Speed Control Bar to limit your maximum speed. See page 19.
Mowing Height
Probably, the best cutting height for your lawn was determined from previous experience. The first
time you mow, set the cutting height a little higher than you would if using a narrow walk-behind
mower. This will help you determine the best way to mow uneven areas so a wider cut does not result
in scalping of the lawn.
NOTE: For more information, see “Adjusting the Deck Height” on page 34.
Mowing Tips
• For the best operation on average lawns, operate the Engine at Full Throttle.
•
Control the ground speed by adjusting the Speed Control Bar.
•
Uneven cutting is often the result of excessive ground speed. To correct uneven cutting, reduce the
ground speed.
•
Tall grass and weeds should be cut with the Mower Deck in its highest setting, then make a second
pass cutting at the desired height.
•
Always keep the Mower Blades sharp. Unsharpened Blades may result in poor cutting and cause
unwanted vibrations that could damage your machine.
Obstacle Tips
Dealing with obstacles in the terrain is easy with your new DR VERSA-PRO Z-MOWER. The following
section explains how to approach most common obstacles.
•
THE MOWER ENGINE'S POWER CAN EASILY THROW STONES, STICKS, AND OTHER DEBRIS UP TO 50
FEET AT GREAT VELOCITY, WHICH COULD CAUSE PERSONAL INJURY OR PROPERTY DAMAGE. DO
NOT RUN THE MACHINE OVER GRAVEL DRIVEWAYS, LOOSE STONES OR MULCH WITH THE MOWER
BLADES SPINNING.
•
ALWAYS CHECK YOUR WORK AREA BEFORE MOWING AND REMOVE ANY DEBRIS THAT MIGHT
TANGLE OR DAMAGE THE MACHINE. IF YOU DO RUN INTO DEBRIS AND THE MOWER BECOMES
TANGLED, TURN OFF THE ENGINE AND DISCONNECT THE SPARK PLUG WIRE(S) BEFORE
ATTEMPTING TO UNTANGLE THE MACHINE.
•
NEVER TOUCH THE EXHAUST AREAS OR THE SPARK PLUG(S)—AS BOTH ARE EXTREMELY HOT.
