* Optional Low Cut Bedknife, Toro part no. 93-9774, is required for height-of-cut below 0.500” (13 mm).
For front (”B”) or rear roller distances (“C”) less than 1” (25 mm) order long cone nut (Part No. 95-2790) to
replace bottom cone nut for improved support.
Note: This guide gives an approximate starting point for new cutting units only.
