Auger Standard Features

  • Single, corner-auger with a side-folding design increases the upper auger length for greater side reach and height.

  • The 14" diameter auger provides unloading speeds up to 300 bushels per minute.
  • 5/16" thick flighting provides long-term, trouble-free operation.
  • Spout-mounted LED unloading light for easy night time operation.
  • Exclusive, single-point auger connection ensures the upper and lower augers are aligned for a smooth and efficient transfer of grain between the upper and lower auger.
  • Electronic balancing of the upper and lower auger sections virtually eliminates vibration for long-term life.
  • The cushioned auger fold cylinder gently folds and unfolds the upper auger into the loading and transport position.
  • When in the unload position, the hydraulic locking mechanism holds the upper and lower augers tightly together for a leak-free seal.



Tank Standard Features

  • Models 6225 and 5225 feature tank capacities of 650 and 550 bushels to meet smaller acreage or field requirements.
  • Tank features an exclusive deep sump design, which funnels grain down into the auger for fast and complete unloading.
  • Steep 36° front and rear tank slopes and a graphite coated interior ensures complete cleanout and faster unloading speeds regardless of grain moisture.
  • Hydraulically operated flow gate features a highly visible position indicator for easily controlling grain flow while unloading.
  • Conveniently located lever-operated gravity unloading door located on the auger sump permits easy cleanout.
  • Exclusive manufacturing process crimps side panels for added strength and exposed seams are silicone sealed for corrosion resistance.
  • Durable, high-grade enamel paint is baked on in tractor red or green for a long-lasting and smooth, automotive-like finish.
  • Front viewing ladder and front and rear shatterproof windows allow the operator to easily monitor tank contents.
