R-Series excavators from Bobcat offer a 15 percent increase in over-the-side stability with the dual-flange track roller system, allowing placement of larger pipes. Strengthened hinges and latches and more ridged, aligned panels reduce vibration in the cab. Along with having large cab openings, the cab has been redesigned with 29 percent more floor space and 15 percent more glass surface area, which includes an improved top window and narrower side pillars for visibility. They have blades with increased downward angles for greater stability when digging on an uneven surface or trenching at an angle, and a boom swing greaseless pin joint for enhanced uptime protection. 800-743-4340; www.bobcat.com.
