7.  Continue to feed the paper into the reel horizontally half an 

inch at a time to check the other blades.

8.  After all blades have been tested, start testing on the other 

end. Feed a strip of paper between a cutting reel blade 

and the stationary blade on the end furthest from the 

ground, and slowly rotate the cutting reel to see whether 

the paper is cut. Continue to feed the paper into the reel 

to test other blades (Fig. 14). 

9.  If most of the blades cut on both ends, the cutting system 

is set correctly. If all or most of the blades do not cut 

on one or both ends, the cutting system needs to be 

adjusted. Follow the instructions for adjusting the blade 

below.

Adjusting the Mower Blades

1.  Each end of the cutting bar can be adjusted separately.
2.  The cutting bar blade, which is located under the reel, is 

able to pivot. The two adjustment screws located at the 

back of the mower move the cutting bar away from the 

blades when they are turned counterclockwise, and closer 

to the blades when they are turned clockwise (Fig. 15).

m

WARNING!

 

Do not overtighten the adjustment screws 

as this could damage the cutting bar. Both screws must be 

tight on final adjustment.

3.  To loosen the blades, use the Allen wrench provided and 

turn both adjustment screws by an equal amount  

counterclockwise.

4.  To tighten the blades, tighten both screws by an equal 

amount by turning them clockwise.

5.  Once the mower blades have been properly adjusted and 

their alignment has been verified, you can now proceed 

to use your reel mower. Align the cutting path indication 

arrow with the previously cut path.

Mowing Tips

Follow the 1/3 Rule

The 1/3 rule is key to an enjoyable mowing experience and a 

healthy lawn.

1.  You should mow your lawn regularly, at least once a week, 

during the growing season.

2.  Be guided by observing the lawn and taking care not to 

remove more than 1/3 of the total height of the turf at any 

mowing session and never more than 1 inch at a time  

(Fig. 16).
