The conventional-tail-swing E32i and zero-tail-swing E35i hydraulic excavators feature a Tier 4-compliant, 24.8-horsepower, naturally aspirated diesel engine. Bobcat says the engine uses some 8 percent less fuel when operated in an available Eco Mode. A new forward-mount instrumentation system is designed to “allow operators to maintain awareness of machine vitals without losing focus on the task at hand” and to simplify interaction with the panel. An available deluxe panel includes an integrated keyless start system, Eco-Mode setting, and access to fuel- consumption and engine/hydraulic-performance data. Both models can use an optional extendable arm, which provides additional reach and allows use of a hydraulic clamp. The new excavators can accommodate 13 attachments, including augers, breakers, plate compactors, grading buckets, trenchers, and rippers. The Bobcat X-Change attachment-mounting system is standard; the hydraulic X-Change system is an option.
