A rear implement hitch is available for the tow-behind model for towing additional implements such as a roller packer or harrow. The tow-between model attaches to the tractor drawbar ahead of the seeding tool so that cart tire tracks are eliminated. It is especially suited for use on hillsides. A choice of four tires and wheels allow maximum floatation in a variety of soil conditions. All operator adjustments are located on the left side of the machine to provide easy operator access.
Meters are also color coded and contained in a cartridge for easy removal.
The metering cartridge at each compartment effectively meters seed or fertilizer into the primary manifold where air carries the material to the secondary distributor for delivery to the furrow openers on the seeding tool. It also allows the meter cartridge to be removed with material still in the tanks, and allows the tanks to be emptied with the meter and primary manifold in place. Also available with the John Deere 1900 commodity cart are three types of meter cartridges to match seed types. A low-volume meter roller features 20 flutes to assure better metering at low rates. It is designed for low seeding rates of 3 to 100 pounds per acre, or for small seeds such as flax, canola, or alfalfa.
