Cutting-Unit System
Maintenance
Blade Safety
A worn or damaged blade or bedknife can break, and a
piece could be thrown toward you or bystanders, resulting
in serious personal injury or death.
•
Inspect the blades and bedknives periodically for
excessive wear or damage.
•
Use care when checking the blades. Wear gloves and
use caution when servicing them. Only replace or
backlap the blades and bedknives; never straighten or
weld them.
•
On machines with multiple cutting units, take care when
rotating a cutting unit; it can cause the reels in the other
cutting units to rotate.
Checking the Reel-to-Bedknife Contact
Service Interval: Before each use or daily
Check the reel-to-bedknife contact, regardless of whether
the quality of cut had previously been acceptable. There
must be light contact across the full length of the reel and
the bedknife (refer to Adjusting the Reel to Bedknife in the
cutting unit Operator's Manual).
Backlapping the Cutting Units
WARNING
Contact with the cutting units or other moving parts
can result in personal injury.
•
Keep your fingers, hands, and clothing away from
the cutting units and other moving parts.
•
Never attempt to turn the cutting units by hand or
foot while the engine is running.

Additional instructions and procedures on
backlapping are available in the Toro Reel Mower Basics
