The new B-Series 3 Caterpillar skid-steer and multi-terrain loaders – SSL models 216B3, 226B3, 236B3, 242B3, 252B3 and MTL models 247B3 and 257B3 – are designed for convenience and control. Specific design refinements for all B-Series 3 models include a redesigned “dead-engine lower valve,” single electronic control module (ECM), which is relocated for improved access and reliability, plus new ECM-enabled features. A heavy-duty battery is now standard equipment on larger models, and a headliner is added to the optional comfort package.
