It is important to keep the flail blades sharp and in good condition to ensure good cutting performance, minimum power consumption, and a good quality of cut.

The flail head is a fine cut flail and should only be used for maintaining grass. Its recommended that a maximum of 1/3 of the total grass length is removed when cut.

The scraper wires are fitted to remove debris from the roller, in dry conditions these may not be required and its recommended they are removed. In damp wet conditions ensure that scraper wires do not get plugged with debris.

The cutting unit floats and can pivot laterally to follow ground contours.

The cutting units are designed to be operated at full engine rpm. Forward speed should be adjusted depending on grass conditions and to not overload the power units or the heads. The lower the forward speed the higher the quality of cut and after cut appearance.

Note: The height of cut is gauged by the rear roller. Blade wear, worn cutting unit pivots, bent/damaged cutting unit pins, and bent/damaged arms can affect the height-of-cut setting.

1. Turn the adjusting-nut assembly on both ends clockwise to decrease the height of cut or counter-clockwise to increase the height of cut (Figure 26).

   

   Figure 26

   1. Height of cut
   2. Adjusting-nut assembly

   Important: Do not attempt to unlock the nut assemblies.

2. Ensure that all cutting units are set at the same height of cut by referring to the indicator rings (Figure 27).

   

   Figure 27

2. Grip the rotor at each end and check for excessive end play.

   Note: If you detect the rotor has excessive end play, contact your authorized Toro distributor.

   Note: If the rotor needs to be replaced or balanced, contact your authorized Toro distributor.

Important: Keep the roller bearings on the cutting units in good adjustment to ensure maximum working life. Excessive roller-end play causes premature bearing damage.

1. Grip the roller and move from side to side and up and down.

2. If there is excessive movement, carefully tighten the nuts at each end of the roller with the wrench just enough to remove any end play (Figure 79).

   Note: The roller should still rotate freely after adjustment. Overtightening the nuts could lead to premature bearing damage.

   Note: Adjust the nuts by an equal amount at both ends of the roller.
