The model 4200 Bulk Bed is available in a 30-inch-wide discharge belt in lengths from 20 to 26 feet long. The bed has a full-length, hydraulically operated side-door to allow the harvester boom to gently lay the potatoes in the bottom of the bed without bruising. A hydraulically operated end door is used to meter the flow of product out of the bed, and a fold-down tailgate makes loading a bed through the back with a piler a simple process.
In 2011, a new option to increase bed unloading speed was introduced. The new control is available to unload the bed in manual or auto mode. In auto mode, initially the bed will unload slowly as more torque and horsepower is needed to start the load moving. As the bed unloads, the belt speed increases automatically as the torque requirement reduces. This allows a constant unloading volume of product, allowing the bed to quickly unload and get back to the field for the next load without delay.
Spudnik Equipment Company LLC, located in Blackfoot, Idaho, started building bulk beds in the 1970s and has been supplying the industry with quality beds ever since.
