Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mount- ing bolts to the top or to the bottom of the spindle shaft. All blades should be positioned equally (See Figure 10).

The unit is shipped with one spacer on top of spindle and four underneath (See Figure 10).

This adjustment does not affect blade pitch.

-NOTE-

For best results, keep the cutter deck high in relation to the engine deck and the blades low in the cutter deck; ie. 4 or 5 spacers below the spindle shaft.

Additional range to the cutting height can be achieved by repositioning the cutter deck in relation- ship to the engine deck. This adjustment also affects the pitch of the deck.

There are three positions for mounting the cutter deck (See Figure 11). For cutting in the lowest position, mount the cutter deck in the top hole (A). For cutting in the highest position, mount the deck in the lowest hole

(C). Setting the cutter deck height will be determined bythetypeofcuttingconditions.

Caster spacers also can be repositioned to change the cutting heights and to change the pitch of the deck (See Figure12).

To adjust the caster spacers, raise the deck and remove the pin and caster wheel. Reposition the caster spacers as needed, then replace the caster, top spacers and pin. Make the same adjustments on the other caster wheel.

To adjust the blade height, move any number of the five 1/4" thick spacers on the blade mounting bolts to the top of the spindle shaft or below the spindle shaft.
