Shields are removed to show the dual belt clutch which is the primary drive source. The emergency stop mechanism is built into the drive unit and can be activated from the front, sides or rear of the box. A separate clutch allows you to start and clear the beaters before you start the main apron conveyors. A simple, trouble-free variable speed drive lets you match just the right unload speed to the crop type, load condition and blower capacity. Main apron unload rate is variable and ranges from 9" up to 11' 6" per minute.

H&S uses three - 18" 4 bar HD spiral type beaters, not augers. These beaters are aggressive in handling tough material and provide an even feed. All three beaters are mounted in the head, not auxiliary panels in the box. Beater shafts are 1 1/4" and equipped with greaseable bearings.

Once the tailgate safety lock is released, the self-locking mechanism unlocks automatically while unloading and locks shut when the tailgate closes.

All industrial forage boxes feature cross Z-iron. Cross Z's are welded to the side channels inline with stakes for added strength.

An optional rear unload drive system with a quick change pin is available on all HDNR forage boxes.

The optional front-to-rear electric roll tarp is a nice feature to keep that valuable forage from blowing out during transport.
