Dual Belt Clutch

H&S Manufacturing HDNR Twin Auger/No Roof Forage Box
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.

3-18" 4 Bar HD Beaters

H&S Manufacturing HDNR Twin Auger/No Roof Forage Box
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.

Automatic Tailgate Lock and Unlock

H&S Manufacturing HDNR Twin Auger/No Roof Forage Box
Once the tailgate safety lock is released, the self-locking mechanism unlocks automatically while unloading and locks shut when the tailgate closes.

Cross Z-Iron

H&S Manufacturing HDNR Twin Auger/No Roof Forage Box
All industrial forage boxes feature cross Z-iron. Cross Z's are welded to the side channels inline with stakes for added strength.
