3.1 INTRODUCTION
To retain the quality of the SNAPPER mower, use
genuine SNAPPER replacement parts only. Contact a
local SNAPPER dealer for parts and service assistance.
For the correct part or information for a particular

mower to an authorized SNAPPER dealer annually for
inspection and addition of any new devices which might
