CUTTER DECK PITCH ADJUSTMENTS

The cutter deck pitch adjustment has been set at the factory and normally will not need to be changed. However, if the pitch needs to be adjusted due to service work performed on the deck, follow the procedure below (see Figure 3).

1.Shut off the engine and remove the key.

2.Support the cutter deck with four blocks (you will be removing the hair pins to make this adjustment).

3.Remove the front hair pins from the front deck support pins.

4.Loosen the jam nuts on the deck support pins.

5.Turn the deck support pins to lengthen or shorten the pins to reach the desired result.

6.Tighten the jam nut, replace the hair pin, and remove the blocks. Check that the desired deck pitch is achieved.

WARNING:

Always wear proper hand and eye protection when working with cutter blades.

-NOTE-

Dress the blade with a file. Using a wheel grinder may burn the blade. Check the balance of the blade. If blades are out of balance, vibra- tion and premature wear of spindle assembly can occur. See your authorized Scag dealer for blade balancing or special tools, if you choose to balance your own blades.

Custom-Cut Baffle Adjustment

The Custom-Cut Baffle is designed to deliver optimum airflow and superior cutting performance in any type of grass. The Custom-Cut Baffle can be raised or lowered to precisely tailor the deck's performance for the type of grass being cut. The baffle can be set in three (3) different positions for optimum performance.

CUTTER BLADES

Do not sharpen beyond 1/3 of the width of the blade. (See Figure 4)

A.3" Position - baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. (See Figure 6, Page 11). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass.

B.3-1/2" Position (factory setting) - baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. (See Figure 7, Page 11). For general purpose cutting, place the Custom Cut Baffle in the 3-1/2" position. This gives the best mix of cutting performance in all types of grass.
