6 ton, 12 row high output Montag unit on an Elk Creek 500 caddy. It currently has a Greenstar Dry Rate Controller and scales connected to a Libra Express system for wireless connection to an ipad or iphone.
I used this unit in place of the T-hitch on a JD 2510H to apply dry fertilizer while putting on ammonia. This could also work well in front of a strip till machine or a mounted planter.
