ADJUSTING ANTI-SCALP ROLLER

NOTE: The anti-scalp rollers are intended to prevent lawn scalping, not to control cutting height. All anti-scalp rollers should be set at the same height.

See figure 16 for anti-scalp locations on models 915067, 055, 057, 059, 501. See figure 17 for anti-scalp locations on models 915065 and 502.

There are two positions:

•Highest Position: Use to disable anti-scalp feature.

•Lowest Position: Use for all cutting positions.

In the lowest position the anti-scalp rollers will touch the ground.
