6.7 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) (early models), or seven (7) (current production) different positions for optimum performance.

3-Position Custom-Cut Baffle Adjustment - EARLY MODELS

A.3" Position - (See Figure 6-9). Baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. In this position the Velocity-Plus cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass.

B.3-1/2" Position - (See Figure 6-9). Baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. Can be used for general purpose cutting. Placing the Custom-Cut Baffle in the 3-1/2" position gives a good mix of cutting performance in all types of grass.

C.4" Position (factory setting) - (See Figure 6-9). Baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck. Placing the baffle in the 4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout".

To adjust the Custom-Cut Baffle height:

1.Place the cutter deck in the transport position.

2.Remove the hardware securing the Custom-Cut Baffle to the cutter deck. See Figure 6-9.

- NOTE -

Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size.

3.Move the Custom-Cut Baffle to desired position. See Figure 6-9.

4.Reinstall the mounting hardware as shown. Torque hardware to 39 lb-ft.

7-Position Custom-Cut Baffle Adjustment - CURRENT PRODUCTION

A.3-1/2" or 3-3/4" Position - (See Figure 6-10). For very tall, wiry or tough-to-cut grass.

B.4" (factory setting), 4-1/4" or 4-1/2" Position - (See Figure 6-10). For general purpose cutting. This gives the best mix of cutting performance in all types of grass.

C.4-3/4" or 5-1/4" Position - (See Figure 6-10). Placing the baffle in either the 4-3/4" or 5-1/4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout".

To adjust the Custom-Cut Baffle height:

1.Place the cutter deck in the transport position.

2.Remove the hardware securing the Custom-Cut Baffle to the cutter deck.

- NOTE -

Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size.

3.Move the Custom-Cut Baffle to desired position. See Figure 6-10.

4.Reinstall the mounting hardware. Torque hardware to 39 lb-ft.
