MOWERBLADE ADJUSTMENT

MOWERBLADE ADJUSTMENT

Thebladeshavebeenpreadjustedbeforeleavingthefactory.

Misalignment can occur resulting in blades that are too loose or too tight. If this happens, you will notice a rough,

unevencut or a hard pushing mower.

All adjustments are made from the rear of the mower (opposite from the bar with the logo decal.) Each end of the cut- ting bar can be adjusted separately.

As you follow the instructionsbelow, refer to Figure 1 for more information.

The cutting bar blade (_ocatedunder the reel) pivots. The front screws move the cutter bar away from the blades, while the rear screws move the cutting bar toward the blades.

Adjustingthe screws is a very sensitive procedure. 1/16th of a turn is considered a major adjustment.

Before tightening one adjusting screw, be sure to loosen the opposing screw an equal amount.

LOOSENING THE BLADES

,, The cutter bar blade must be moved further from the cutting reel.

Loosen both back screwsequally by turning them counter-clockwise.

Tighten both front screwsequally by turning them clockwise.

TIGHTENING THE BLADES

The cutter bar must be moved closer to the cutting reel.

Loosen bothfront screws equally by turning them counter-clocl_wise.

Tighten both back screwsequally by turning them clockwise.

CHECKING ADJUSTMENTS

Turn mower upside down.

insert a piece of paper (i.e., writing or newspaper) between the cutter bar and the reel blades, and carefully turn the reel blades by hand.

All blades shouldslice the paper evenly the entire length of the cutter bar while the reel turns smoothly.

If the mower has an uneven cut, an adjustment should be made to the appropriate side of the blades to attain an even cutting action.
