The total capacity of the C850 is 850 bu, measured by conveying product into the tank. The front tank is dedicated for low rate applications and holds 50 bu. The remaining three tanks in order of front to rear are 260 bu, 130 bu, and 410 bu.
John Deere air cart tanks are solid molded polymer, known for superior corrosion resistance compared to steel while providing semi translucency allowing for visual verification of product level in day-time operation. Each tank is mounted in a cradle frame to eliminate interference between each other. The polymer material does not require weldments like on steel tanks. Weldments on steel tanks are prone to failure over time as the metal is fatigued under stress.
The improved top bevel design on tanks allow for greater capacity and meets 850-bu capacity without the need for shoveling product into the corners while conveyor filling.
Each tank has a wide single opening, which means it is easy for access for the conveyor and entry to the tank. Inside each tank is a ladder for clean-out access. Ladders in the tanks have been designed so that material cannot build up on steps. Top rails have been capped and sloped to ensure product sheds from the surface. When cleaning out the cart, the tanks slope steeply at bottom for product to flow easily and each tank is accessible for fill and clean-out with the conveyor.
Tanks come equipped with digital pressure sensor, ultrasonic bin level sensing, and camera-ready harnesses mounted from the factory.
