3-18" 4 Har HD Spiral Type Beaters

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
H&S uses three - 18" 4 bar HD spiral type beaters - not augers. The beaters feed evenly and are aggressive in handling tough material. All three beaters are mounted in the head, not auxiliary panels in the box. Beater shafts are 1 1/4" equipped with greaseable bearings.

Optional Folding Cross Conveyor

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
An optional 12" folding cross conveyor extension is available for apron unload models.

Simple Variable Speed Drive

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
A simple trouble-free variable speed drive lets you match just the right unload speed to the crop type, load condition and blower capacity. A bronze worm gear is standard. #80 drive chain drives the main apron drive shaft. The main apron drive shaft is 1 3/4" stress proof shafting. Main apron unload rate is variable and ranges from 9" up to 12' 6" per minute.

Clear Beaters before you start Main Apron

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
A separate clutch allows you to start and clear the beaters before you start the main apron conveyors. The HD clutch can be used to engage just the cross conveyor, the cross conveyor and beaters, or the cross conveyor, beaters and main floor apron in any speed.

Dual Belt Clutch

H&S Manufacturing HD 7+4 Front and Rear Unload 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.

Switch from Front to Rear Unload Easily

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
To switch to rear unload simply remove the drive lock pin from the front and insert it into the rear apron drive sprocket. A 3 shaft system (drive, tightener and idler shafts) maintain the proper chain tension and position drive.

Self Locking Tailgate

H&S Manufacturing HD 7+4 Front and Rear Unload Forage Box
When being used as a front unload box, the drive lock pin is locked into the main apron drive sprocket. Once the tailgate safety lock is released, the self-locking mechanism unlocks automatically while unloading and locks shut when the tailgate closes.
