At a glance

GenerationE Series (marketed as 303.5E CR); succeeded by the 303.5E2 CR and the current 303.5 CR, so confirm the exact series letter on the serial plate when comparing listings.

Canopy vs cabCanopy with FOPS/TOPS (falling-object and tip-over) protection is the factory standard; the enclosed cab with heater and air conditioning is optional and adds around 180 kg, so check which configuration a used unit carries.

Tracks and undercarriageRubber tracks are standard with steel track optional; on any used mini check track wear, sprocket and roller condition, since undercarriage refurbishment is a major cost item.

Configuration dependenceWeight and dig figures vary with stick, blade, track and cab options; standard equipment includes a swing boom, dozer blade with float and two-way auxiliary hydraulic lines.
