John Deere FM2112 Lawn Mower User Manual


 
In order for the mower to work properly, and to always obtain a precision cut with lower
HP requirements thus keeping cost down, proper blade maintenance is important.
Blades must be kept sharp, at their original length and corners maintained. A blade
must be replaced if, due to wear or damage, its original shape has been distorted.
Installing or removing blades
If the mower blades need to be installed, do the following:
1. The blade turns in a counter clockwise direction when viewed from the bottom of
the deck. The cutting edge must be towards the direction of rotation. The lift wing of
the blades is closest to the deck and the cutting edge away from it (see fig. 18).
2. Install the cup washer (see fig. 18) over the blade bolt and secure the blade in place
as described above.
3. With a wrench, block the spindle and tighten the bolt to 103 lb. ft. (see fig. 19).
4. To remove the blades reverse the procedure.
WARNING: Do not substitute blades or any bolt for the blade retaining bolt.
Company blades and blade retaining bolts are specially made for this application.
