WARNING

Once blade is disengaged it should come to a stop in 3 seconds or less. If the blade continues to rotate after 3 seconds the blade brake must be adjusted. DO NOT continue to operate the machine if the blade brake is not operating properly.

4.2.2. BLADE BRAKE ADJUSTMENT

The automatic Blade Brake should stop the blades within 3 seconds anytime the blades are disengaged by moving blade lever to the "OFF" position or by releasing the Blade Pedals. When the Blade Brake is properly adjusted there should be 1/8" to 1/4" clearance between the Blade Engagement Lever and the back of the Latch Plate. Check this by disengaging the Blade Lever and depressing the Blade Pedals as shown in Figure 4.2. If clearance is greater than 1/4" perform the following adjustment.

1.Remove Belt Cover. Refer to Section “BLADE BELT COVER REMOVAL”.

2.With the blade engagement lever disengaged, hold the blade pedals down and measure the distance between the front of the blade lever and the rear of the latch plate. The dimension should be 1/8" to 1/4" clearance between lever and plate. See Figure

4.5.If the dimension is incorrect go to step 3.

3.If dimension is greater than 1/4", rotate nut clockwise to increase brake tension. If dimension is less than 1/8", rotate nut counter-clockwise to decrease brake tension. See Figure 4.4.

4.Reinstall spindle cover.

4.2.3. MOWER DECK ADJUSTMENT (Side-To-Side Levelness)

Before making deck leveling adjustments, check the tire pressure. Front tires 12 psi, rear tires 12 psi. If tires are properly inflated and mowing is still uneven, adjust side- to-side deck levelness.

1.Place Rider on a smooth level surface.

2.Follow WARNING statement found on this page.

3.Place a piece of angle iron, pipe, or similar object under center of deck at the rear.

4.Remove rear hanger chains and allow center, rear of deck to rest on angle iron.

5.Measure the distance from blade tips to floor. If the measurement is within 1/8” from side-to-side, the deck attitude is satisfactory. If difference from side-to-side is greater than 1/8”, continue with adjustment.

6.Loosen the carriage bolt and nut retaining the left side of the front lift arm and adjuster. Only loosen the bolt and nut to the point where some tension remains but lift arm can be moved.
