Wide vs standard — when to choose 400
Go wide (400) for more flotation and less ground pressure on soft, muddy or turf ground; stay standard (320) for tighter spaces, lower cost and slightly better side-stability on hard ground. Pitch (86mm) and link count (49) are identical — only width changes, so the sprocket and idlers are unaffected. Always run a matched pair.
Tread options
C-lug/bar (traction + self-cleaning), multi-bar/zig-zag (road and hard-surface grip), block (balanced), turf (finished surfaces). Specify ground type and machine.
