2010-2023 JCB 437 ZX WHEEL LOADER

The JCB 437 ZX Wheel Loader is a robust construction machine designed for high productivity and durability. Powered by a Cummins QSB 6-cylinder, 4-stroke direct injection turbocharged engine delivering 183 hp (136 kW) gross power and 161 hp (120 kW) net power at 2100 rpm, it meets EU Stage IV and US EPA Tier 4 Final emission standards. The engine features a cyclonic pre-filter air cleaner and hydraulically driven cooling fan for efficient operation. The loader has an operating weight of approximately 33,570 lbs (15,227 kg) and offers a Z-bar bucket with a heaped capacity of 3.1 cubic yards (2 m³) and a breakout force of 39,566 lbs (17,947 kg), suitable for heavy-duty material handling. Its hydraulic system incorporates a variable displacement pump with a flow capacity of 33.3 gal/min (125 l/min) operating at 250 bar, enabling fast cycle times with a total hydraulic cycle of 12.9 seconds. The machine has a 4-speed non-lockup torque converter transmission with maximum travel speeds of 23.6 mph (37 kph) forward and 16 mph (26 kph) reverse. The wheelbase measures 10.1 ft (3 m), with dimensions optimized for site maneuverability, including an articulation angle of 40° and a turning radius of 19.9 ft (6 m). Key structural features include heavy-duty axles with optional differentials for varied terrain traction and rear axle oscillation of 10.5°. The cab offers compliance with ROPS/FOPS standards, excellent operator visibility, and ergonomic controls with a 24 V electrical system and 120 A alternator. Fuel capacity is 71.4 gallons (269 L), with a DEF tank capacity of 10.6 gallons (38 L) supporting selective catalytic reduction for emissions control. The dump clearance at maximum lift is 9.4 ft (3 m), and the bucket width is 9 ft (3 m), making the JCB 437 ZX an efficient, versatile wheel loader for construction and material handling tasks.
