At a glance

GenerationC Series midi (marketed as 308C CR), mid 2000s production; succeeded by the 308D and later 308E lines, so confirm the exact series on the serial plate when comparing listings.

Stick and blade configurationTwo factory sticks (1665 mm and 2210 mm) trade breakout force against dig depth and reach, and the dozer blade is optional; verify which setup a specific machine carries.

Tracks and undercarriage wearOffered with steel triple grouser shoes or segmented rubber track; on any used unit inspect track, sprocket, idler and roller wear, since undercarriage refurbishment is a major cost item on tracked machines.

Configuration dependenceOperating weight and lift capacity vary with shoe width, stick length and blade fitment; lift charts differ between blade-up and blade-down operation.
