Blade Removal And Installation
!
CAUTION
Depending on blade rotation, bolts attaching mower blades to
their respective spindles may be either left hand or right hand.
Prevent spindle and/or bolt damage by knowing which hand
the threads are before removing and/or tightening any blade
mounting bolts.
Refer to Figure 5-2 & Figure 5-3:
1. Verify blade rotation and bolt thread type (right hand
or left hand) before loosening center blade bolts and
removing blades to be sharpened or replaced.
Refer to Figure 5-4 & Figure 5-5:
2. Remove blades by grasping the blade end (#1) with a
rag or thick padded glove while loosening the blade
mounting bolt (#4).
3. Remove blade bolt (#4) and Washer (#5) from blade
being replaced.
4. (Model AFM4216 Only.) Remove two outside
bolts (#6) from blade bar (#2).
5. Reinstall blade (#1), blade washer (#5) and bolt (#4).
Care should be taken when installing the blade bolt
to not get it cross threaded and to know if the bolt is
right hand or left hand. Do not exceed 55 ft.-lbs. of
torque on bolt.
6. (Model AFM4216 Only.) Reinstall the two outside
bolts. Tighten to correct torque listed in the Torque
Values Chart in the “Appendix” section on page 43.
NOTE: Blade bolt on the left hand deck is right hand
threads. Blade bolts on the right hand and center
decks are left hand threads.
Refer to Figure 5-5, Model AFM4216 only:
The two outside blade bar bolts (#8) are always right
hand threads.
IMPORTANT: Replace blades with Land Pride blades
only.
IMPORTANT: Always install blades with cutting edge
facing direction of blade spindle rotation and with wing
tips pointing up towards bottom of deck.
IMPORTANT: (AFM4216 ONLY) Loctite is not
required if blade (#1) is removed without removing
blade bar (#2). However, If blade bar (#2) is removed
from spindle shaft (#3), then apply loctite 243 to
exteranl spindle shaft threads and to center bolt
threads (#4).
