Blade Adjustment - Toro Groundsmaster 455-D Service Manual

Blade Adjustment

To assure proper operation of the cutting unit, there
must be 0.25 ± 0.12" clearance between the tips of the
wing and center cutting unit blades.
1. Raise cutting unit so blades are visible and block
center deck section so it cannot fall accidentally. Wing
decks must be horizontal to center cutting unit.
2. Rotate a center and adjoining wing blade so there
blade tips are aligned. Measure distance between blade
tips, distance should be approximately 0.25 ± 0.12".
3. To adjust distance, locate adjuster bolt on rear outside
corner of center cutting unit. Loosen jam nut on adjuster
bolt. Loosen or tighten adjuster bolts until 0.25 ± 0.12"
clearance is attained, then tighten jam nut.
4. Repeat procedure on opposite side of cutting deck.
IMPORTANT: Blade plane is adjusted at the factory
and should not need further adjustment.
