Avalanche 98-Series Dual Auger Grain Carts

The Brent® Avalanche® dual-auger grain carts have set powerful standards for unloading speed, convenience, capacity and durability.  The all-new 98-Series of Avalanche grain carts carry on this tradition and give the operator more auger side reach and height along with choice of right- or left-hand unloading to meet individual preferences.  The dual-auger design provides a narrow transport width and low profile for greater stability and ease of transport and features the fastest unloading speeds, no matter the moisture of grain.  In addition to the industry’s first pivoting vertical unloading auger, the 98-Series is standard with a 4-way directional downspout that is operated on the tractor’s SCV remotes.  The all-welded construction, rubber cushioned tongue suspension and heavy-duty dual-belt drive system ensure years of dependable service.  Capacities range  from 2,500 to 1,100 bushels and with unloading speeds up to 1,000 bushels per minute depending on model, operators can get back to the combine quicker to keep harvest moving smoothly.  Bigger, faster, better.  The Avalanche 98-Series dual-auger grain carts feature dynamic performance that now pivots to new heights.

    Auger

    Unloading

    • Unload up to 1,000 bushels per minute, even in high-moisture grain, on models 2598 and 2098 with a 24" vertical unloading auger and 20" horizontal floor auger.  Models 1598, 1398 and 1198 feature a 22” vertical auger and 20” horizontal auger for unloading up to 850 bushels per minute.
    • Models 2598 and 2098 feature a 36” longer vertical auger and models 1598, 1398 and 1198 feature a 25” longer vertical auger for increased auger height and side reach to clear taller trailers and reach over obstacles.
    • Depending on operator preference, the 98-Series grain carts can be ordered as a left- or right-hand unload from the factory.
    • Pivoting unloading auger provides up to 6' 5” of height adjustment and 5’ 1” of side reach adjustment depending on model.  This allows the operator to lower the auger to the truck and raise the auger when pulling away to clear obstacles.
