With the Willmar S-600 and S-800 spreaders, you will find you spend more time in the field and less time loading up. The S-600 and S-800 are sturdy, productive, accurate and reliable spreaders that feature a 6- or 8-ton capacity with an optional 8-horsepower engine for driving the spinner system, braking for improved safety and heavy-duty hitches with safety chains. Both models come standard with a 540 PTO while more versatility is offered via a dual-drive 540/1000 PTO option. Also, both models can be configured with either single- or dual-spinners. Both options produce the same spread patterns of other Willmar equipment.

A multi-lead, spring suspension system is positioned on both sides of each axle on these Willmar spreaders to reduce bounce and improve stability. You control application rates in low or high ranges, from 311 to 1033 pounds o material per acre, with the two-speed conveyor.

The conveyor system is made of a mechanically simple chain and gear. This system is directly driven by the spreader’s ground speed through chains and pulleys. Should the conveyor belt unintentionally stop, a slip clutch prevents damage to components while conveyor shields guide the slackened chain over the cross members to prevent metal-to-metal contact.

The S-600 and S-800 were built with materials designed to resist the harsh realities of changing weather conditions as well as corrosive materials. The hopper, conveyor and ground-drive chains, as well as the hopper, are made of stainless steel while the frame is constructed of reinforced structural channel steel. These spreaders are then finished with a high-performance, chemical-resistant, epoxy-based, rust-inhibiting primer and a super-tough, acrylic urethane combination for corrosion-resistance to help protect and extend the life of them, while corrosion-resistant phenolic flooring helps to facilitate smooth material flow without buildup from under the conveyor chain.

On the safety side of things, the S-600 and S-800 are equipped with lighting and reflective devices that meet ASAE S279 lighting and marking requirements for agricultural equipment operating on the road while the S-800 has a window at the front to provide you with a clear view of the product remaining in the hopper.
