4.  Pull both sides of the lower handle bars over the posts 

on the mower body. Press inward on the handle bars to

Operation 

Cutting height adjustment

1.  The cutting height of the 16" (40.6 cm) reel mower can be 

adjusted from 1.1" to 2.9" (27 to 73 mm) by moving the 

9-position height adjustment levers to the desired setting. 

The height adjustment levers are located next to the 

smaller wheels.

2.  In order to set the mower to its lowest cutting position, 

pull the adjustment levers on both sides, one at a time, 

and set them to position A (Fig. 4). 

3.  In order to set the mower to its highest cutting position, 

move the adjustment levers on both sides to position B 

(Fig. 4). 

  NOTE: The two adjustment levers MUST be set to the 

same position (height).

4.  Other cutting heights are achieved by moving the 

adjustment levers to the settings between the highest and 

lowest positions.

Ensuring a clean cut

m

WARNING!

 The steel blades are extremely sharp. 

To avoid injury, do not touch the blades while making 

adjustments. 
NOTE: Although the blades are pre-adjusted prior to leaving 

the factory, it is recommended that the adjustment be verified 

prior to first use.

NOTE: Vibrations during shipping can cause blade 

misalignment, which often causes the blades to become too 

loose or too tight. This will result in a rough, uneven cut, or 

make the mower difficult to push (Fig. 5).

1.  To verify proper blade alignment, place the mower on a 

flat surface. Remove the handles and

 turn the mower reel 

upside down to expose the cutting bar.

2.  Insert a sheet of paper between the blade reel and cutting 

bar, then slowly turn the wheel by hand (Fig. 6).

3.  All the blades should slice the paper evenly along the 

entire length of the cutting bar while the reel is turned 

smoothly.

4.  If the mower cuts the paper intermittently, adjustment 

should be made to the appropriate side of the blades to 

achieve optimal cutting performance.
