Bobcat 331

Bobcat 331 D-series compact excavator (S/N 232511001 and above; Kubota V2203-EB 29.9 kW, 320 mm rubber tracks) from the Bobcat Company D-series excavator brochure (Machine.Market copy), cross-checked with the Bobcat 331/331E/334 Operation & Maintenance Manual 6901957 (2003). The 331 is discontinued. Neither document letters its dimension drawing, so the Dimensions group has no letters; the A-E letters are those the brochure prints for the working range.
