The John Deere T660I Hillmast Grain Harvester is a modern combine harvester manufactured by John Deere, a leading builder of agricultural machinery for grain and cereal crop harvesting. This 2020 model is a high-capacity self-propelled machine designed for efficient threshing and grain collection across varied terrain.
The machine is powered by a John Deere six-cylinder engine with a displacement of 9 litres, equipped with twin turbochargers and air-to-air cooling.

Engine hours recorded at time of listing are 800, with 504 threshing hours.
The harvester features a three-speed electric gearbox with a maximum speed of 20 km/h. The distinctive HillMaster system is a self-leveling mechanism that maintains the combine stable and horizontal when operating on slopes and uneven terrain, a key feature for challenging topography.
The threshing system uses a 660 mm diameter drum paired with a 500 mm return beater rotating at 600 rpm, an 800 mm finger separator adjustable to 380 or 760 rpm, and a 400 mm rear beater operating at 450 or 900 rpm.

It features a refrigerator, heated and electrically adjustable mirrors, a fully adjustable air seat with an additional instructor seat, a radio with two speakers and external antenna, and a CommandCenter touchscreen display.
