Case Wheel Loader 821G previewCase Wheel Loader 821G
CASE’s Tier 4 Final SCR engine technology makes the 821G wheel loader an ideal choice for high production loading and hauling applications. The innovative Selective Catalytic Reduction (SCR) technology maintains peak engine performance while increasing fuel efficiency, keeping exhaust temperatures low, eliminating regeneration and avoiding the need for replacing expensive Diesel Particulate Filters (DPF). The optional 5 speed transmission with lock-up torque converter provides faster acceleration and travel speeds up to 40 km. In addition to more than 18,000 kg of breakout force, the 821G also features the CASE mid-mount Cooling Cube, which provides direct access to cool, clean, ambient air for each cooler, as well as an optional reversing fan to keep the coolers clean and keep you and your machine working, instead of cleaning clogged coolers.
