The John Deere 9780i CTS HillMaster combine is built around an 8.1-liter, 6-cylinder PowerTech engine delivering about 355 HP (≈ 264-270 kW), paired with a hydrostatic transmission and John Deere’s HillMaster body-levelling system to maintain performance and traction on slopes. Its standard grain tank holds approximately 10,000 liters, making it well-suited for long harvest runs without frequent unloading. Fitted with the 625 Premium Flow header, it offers an expansive cutting width suitable for high throughput, especially in broad acre operations. The threshing system uses a 66 cm diameter concave cylinder and 140 cm width, together with secondary threshing support, ensuring efficient grain separation. Large front tyres (800/65R32) and wide rear tyres (540/65R30) provide stability and flotation, while a spacious, comfortable cab and hydraulic header height/tilt adjustments allow for precise control. Overall, the 9780i CTS with the 625 header is ideal where both output and grain quality must be delivered across varied terrain.
