4.4 Recommended Blades
Ultra Low Blade (Part No. 063265 for 21” Blade and 063266 for 25” Blade)
Use Ultra Low Lift Blade when the conditions are dry and in sandy soil areas. When con-
ditions like this are evident, lift created by the cutter blades can be reduced, decreasing
the abrasion wear to the cutter blades and deck caused by sand. The Low Lift Blade will
also help reduce cutter deck blowout during the conditions stated above.
Low-Lift Blade (Part No. P246 for 21” Blade and P849 for 25” Blade)
Low-Lift Blade is recommended for 1”-2” cutting height. Use a Low Lift Blade when the
conditions are dry, the region is experiencing a drought, in sandy soil areas or when per-
forming seasonal scalping. When conditions like this are evident, lift created by the cutter
blades can be reduced, decreasing the abrasion wear to the cutter blades and deck
caused by sand. The Low Lift Blade will also help reduce cutter deck blowout during the
conditions stated above.
High-Lift Blade (Part No. P128 for 21” Blade and P701 for 25” Blade)
High-Lift Blade is recommended for cool season grasses and cut heights of 2” and above,
unless in sandy conditions. These blades are shipped standard on all mowers.
Use a High Lift Blade when the conditions are extremely wet or heavy. The High Lift
Blades will create greater lift that may be needed in difficult cutting conditions. Additional
deck cleaning may be required when using High Lift Blades.
Gator Mulching Blade (Part No. P322 for 21” Blade and P848 for 25” Blade)
Mulching blades are designed for use with a mulching (discharge block-off) plate or with a
complete mulching system. These blades feature a high lift, “double-cut” edge for quick,
thorough shredding of grass clippings, leaves and debris.
