3.  Following this rule will stimulate the turf’s root growth, 

maintain its health, and encourage its natural ability to 

crowd out unwanted weeds.

Tall Grass Requires Incremental Cutting

1.  For extremely tall grass, set the cutting height at the 

mower's maximum setting for the first pass, and then 

reset it to the desired height and mow a second or third 

time (Fig. 17).

2.  Removing too much of the turf’s height, especially in the 

heat of summer, can cause root shock and weaken the 

lawn; bringing down the height by successive mowing 

over two or more days can avoid this damage and 

maintain the health of the turf.

3.  If the lawn is overgrown (to higher than 4 inches) it may be 

necessary to use a brush cutter to remove the excess turf 

mass before resuming mowing at normal heights.

NOTE: Do not cover the grass surface with a heavy layer 

of clippings. Consider using a grass collection system and 

starting a compost pile.

Transporting the Mower 

During normal operation, the blade reel will turn anytime the 

mower's front wheels are turning. To safely move the mower 

from one location to another without the blade reel turning, 

simply pivot the handle over the reel and push the mower from 

the opposite side. Pushing the mower in this manner (transport 

mode) prohibits the blade reel from turning (Fig. 18).

Care + Maintenance 

1.  Minimum care is required to ensure smooth operation of 

your mower.

2.  To avoid damage to the mower or cutting blades, keep the 

area to be mowed free from debris.

3.  For best results, regularly apply lubricant to the mower’s 

cutting surfaces, cutting reel axle shaft, and wheels.

Sharpening the Cutting Blades

1.  Spread a thin layer of lapping compound on the front edge 

of the reel blades.

2. 

Adjust the cutting bar so that the blade has light but firm 

contact across the full width of the bar. 

m

CAUTION!

 Do not overtighten the adjusting screws, as 

this could damage the cutting bar. Tighten both screws during 

final adjustment.

3.  Turn the reel blades until the front edge of the cutting bar 

blade is polished.

m

WARNING!

 Clean any grinding compound or debris 

from the cutting bar blade, reel blade, pinions, and pawls.
NOTE: Use industrial or valve lapping compound between 100 

and 240 grit.
