Equipment Overview
The John Deere 644 is a mid-size wheel loader built for demanding material handling tasks such as aggregate loading, site preparation, and construction support, current in John Deere’s mid-size wheel loader range as the 644 P-Tier and X-Tier. It delivers 186 kW (249 hp) and an 18,700–18,900 kg operating weight, suited to a 3.1–3.6 m³ bucket capacity.
Power drives a completely redesigned Z-Bar linkage that improves visibility and provides a high degree of parallelism, minimising load rollback when using forks. Enhanced performance buckets with curved side cutters and integrated spill guards improve fill rates, and SmartWeigh payload weighing delivers accurate, easy-to-calibrate load measurements for hitting target weights efficiently.
