Slotting directly into the heart of the mid-range loader class, the JCB 424ZX bridges the performance gap between compact maneuverability and heavy-production capability. Propelled by a DPF-free, 4-cylinder JCB EcoMAX 4.8-liter engine generating 145 gross horsepower, it delivers ample torque and tractive muscle without the operational disruptions of exhaust regeneration. Packing a solid 29,205 lb operating weight and an aggressive Z-bar linkage, the 424ZX anchors itself firmly into the ground to provide ferocious digging effort in dense aggregates, scrap, and general construction site work.

Engineered around a standard 2.6 yd³ bucket, this model is finely optimized to maximize per-pass cycle volumes while curbing total ownership costs. Operators can handle loaded maneuvers with total assurance, supported by a steadfast full-turn tipping load of 19,433 lbs (and a 9,717 lb rated payload). Loading high-sided haul trucks and site hoppers is fast and efficient thanks to an elevated 115.0-inch maximum dump clearance and a fast 11.0-second total hydraulic cycle time, delivering large-loader productivity on an economical footprint.
