Features

Dual-Auger Harvesting Power

Augers

  • The 20" diameter horizontal floor auger feeds the 24" vertical auger on model 2020 for unloading speeds up to 1,000 bushels per minute or the 22" vertical auger on models 1620, 1320 and 1120 for unloading speeds up to 850 bushels per minute
  • Exclusive, full-length Extended Wear auger flighting manufactured of high-grade steel with a 7/16" thick outer edge for maximum life
  • Electronic balancing of the upper and lower augers provide longer-life and smooth operation at all speeds
  • Patented Soft-Start auger mechanism ensures smooth engagement of the upper and lower auger sections
  • Pivoting vertical unloading auger adjusts from 16' 6" to 10' 6" in height which allows the operator to lower the auger to the truck when unloading and raise the auger when pulling away
    • Adjust auger reach up to 8' 11" from the cart for precise grain placement without repositioning the grain cart
  • The unloading auger fits completely within the cart's width for transport and storage ease
  • Easy-to-operate auger stand provides in-field position for auger, resulting in quicker raising and lowering
  • Dual L.E.D. vertical auger spotlights automatically turn on when the auger is unfolded for easier night time unloading
  • The vertical auger's hinged cleanout door features tool free access which allows for convenient pit dumping and cleanout

Downspout

  • Standard bi-directional downspout allows you to easily move the downspout in-and-out for precise grain placement
  • An optional pistol-grip joystick remote provides 4-way downspout operation which allows the operator to move the downspout left/right and in/out for easily topping off trucks
    • The optional joystick also controls the auger pivot up/down, auger raise/lower and flow door open/close

Drivetrain

  • The exclusive drivetrain design on Unverferth dual auger grain carts combines a belt drive for the 20" horizontal auger and a heavy-duty direct-drive 90-degree gearbox for the vertical auger
  • Belt-drive features dual, four-strand belts and dual spring-loaded tensioners for long life and easy maintenance
  • Floor auger can be manually disengaged if needed
  • Quick-couple 1000 RPM P.T.O. shaft with overrunning friction clutch helps protect driveline

Large Carrying Capacities

Tank Design

  • Large carrying capacities of 2000, 1600, 1300 and 1100 bushels to meet your operation's needs
  • The 20-Series double auger grain cart design allows the tank to have a lower profile and low center of gravity for in-field stability and easy combine unloading
  • The steep floor slopes, graphite-coated interior and recessed floor auger intake provide quick and clean unloading
  • Standard, 16" hydraulic flow-control gates over the floor auger allow the operator to meter the grain flow
  • Rear, single-point opening floor auger panels permit easy clean out between crops
  • Three front and one rear shatterproof windows, front viewing ladder and high-intensity L.E.D. spotlight mounted inside the tank make for convenient load checking
  • The exclusive manufacturing process crimps sides for added strength and a sleek appearance
  • Exposed seams are silicone sealed for corrosion resistance
  • Flashing L.E.D. amber and red taillights with SMV sign and transport chains for safe road transport
  • Durable top coat of high-grade enamel paint is baked on in tractor red or green for a smooth, automotive-like finish

Weatherguard Tarp

  • All 20-Series dual-auger grain carts come standard with a rollover tarp for protecting load contents
  • Custom-design offers the fit, appearance and ease of operation that Unverferth customers expect
  • Low-profile tarp bows are reinforced to eliminate sagging and the heavy-duty, 18 oz. black canvas provides longer life
  • Semi trailer locking design for optimum protection from high wind and moisture

Heavy-Duty Construction

Frame

  • Rubber-cushioned tongue suspension provides a smoother ride over the roughest terrain
  • Tubular steel mainframe, 12-gauge steel shell, reinforced gusset wheel hub design and special alloy, stress-proof spindles contribute to the durability of the grain cart
  • Heavy-duty 12,000 lb. drop-leg jack for safer storage and standard transport chains for added safety

In-Line Fixed Tandems

  • Available on 2020 and 1620 double auger models
  • Oscillating in-line tandems are fixed for an economical design that provides high-flotation for reduced compaction
  • 12-bolt hubs and a heavy-duty frame structure ensure long-term trouble-free use
  • Model 2020 features 1050/50x32 tires and model 1620 features 900/60x32 tires

High-Flotation Single

  • Available on 1320 and 1120 double auger models
  • Choose 76-50.00x32 or 1250/50x32 on models 1320 & 1120 or 35.5x32 or 1050/50x32 tires on model 1120 only

Walking Tandem Duals

  • Available on 1320 and 1120 double auger models
  • Innovative design allows the cart to trail easily through the field and features independent operation from front to rear, allowing the cart to "walk" over obstacles
  • Can be adjusted for 30" or 36" row spacings
  • The entire wheel assembly swings out for easier tire/wheel maintenance
