4 Wheel Drive Mounted Swingarm

Puck’s 4-Wheel Drive Mounted Swingarm is the easiest and most efficient way to run an applicator. Fits right on the tractor, the 4WD Swingarm allows you to turn around quickly and precisely, navigating rough terrain and difficult field conditions to deliver nutrients to the ground. These accurate turns eliminate the need for backing up, and your hose stays flat and level during all turnarounds. The 4WD swinger easily connects to Puck manure injection toolbars for a simple setup for dragline application. Operating independently of both the toolbar and the tractor, the 4WD Swingarm can easily adapt to your operation and allows you to change out tillage tools with ease.
