Dismount Hoppers
Hoppers and their mount, are removed to:
• provide clearance to install new hopper braces;
• protect the hoppers from welding damage; and,
• ease update of meter supports.
The hoppers must be empty.
Supports are required. If an original export shipping rack
is available, it would be ideal. Otherwise, provide two
wide or four narrow supports of equal height, at least
33 cm (13 in.) in height.
