• Classification “B” is wide shoe whose usage is limited. Check the precautions for use and the using condi-
tion, and then use a suitable shoe.
• When selecting the shoe width, choose the narrowest shoes possible to bring the machine within the range
where there is no problem regarding the machine flotation and ground contact pressure. If wider shoes than
necessary are used, the load on the track shoes will increase. It may cause problems such as bending of
the shoe, cracking of the link, damage of the pin, and looseness of the shoe bolts.
