COMMANDER - Model T855 - Tractor with Attachments
From Rockwheel Tractor Attachments
The T855 COMMANDER 3 tractor bullies through most surfaces with a powerful ATAAC Caterpillar C9 ACERT Tier 3 electronic engine. When equipped with a trencher attachment, it handles 6’-12’/1.8-3.7 m rock-trenching jobs for utility, water or sewer installations. With a Terrain Leveler surface excavation attachment, the T855 makes short work of surface mining, site preparation, road demolition or soil remediation.
