18' HDNR Forage Box



  • “HDNR" Forage Boxes are available in either HD 7-4 (cross conveyor), or HD Twin Auger front unload systems w/PTO front unload drive as standard, and hydraulic drive front unload as optional.
  • The aluminized forage boxes are available in front & rear unload.
  • A simple trouble-free variable speed drive lets you match just the right unload speed to the crop type, load condition and blower capacity.
  • H&S uses three - 18" 4 bar H.D. spiral type beaters - not augers. Aggressive in handling tough material, they are even feeding. All three beaters are mounted in the head, not auxiliary panels in the box. Beater shafts are 1 1/4" & equipped with greasable bearings.
  • A separate clutch allows you to start and clear the cross conveyor or augers before you start the beaters or main apron conveyors.
  • HDNR forage box frames feature heavy 5" channel cross members and 2.5" x 2.5" side stakes.
  • On all rear unload boxes, once the tailgate safety lock is released, the self-locking mechanism unlocks automatically while unloading and locks shut when the tailgate closes.
  • An optional 12" folding cross conveyor extension, or a 24" spring assist cross conveyor extension can be ordered on the HDNR 7-4.
  • Options include a gravity unload grain hopper for small grains, and an front-to-rear electric roll tarp to keep that valuable forage from blowing out during transport.
