Sturdy, productive, accurate and reliable — the S-600 and S-800 are all that and more. Featuring 6- (5454.5 kg) or 8-ton (7272.7 kg) capacities, an optional 8-hp (5.9 kW) engine for driving the spinner system, braking for improved safety and heavy-duty hitches with safety chains, you'll spend more time in the field and less time loading up. Both spreaders are available in dual- or single-spinner configurations. The S-600 is also available in narrow track dual- and single-spinner versions. Dependable ground-drive, two-speed conveyor system. PTO-driven dual spinners with four adjustable curved blades on each, or a single spinner with six adjustable blades. Easy setup: Hitch the spreader to your tractor, connect the PTO, set the gate height •Material divider delivers fertilizer to spinners; adjustable baffle plate controls material flow. Multi-leaf spring suspension with rocker arms for equal load distribution. Axle options from 62" to 88" with two- or four-wheel brake options. 40' pattern dual spinners deliver an 80' swath width. 50' pattern dual spinners deliver a 100' swath width. Willmar spreaders are built with materials that resist the harsh realities of changing weather conditions and corrosive materials. The hopper, conveyor and ground-drive chains along with the hopper are made of stainless steel, while the frame construction is reinforced structural channel steel.
