Automatic Sprayer Shutoff
"When planting corn, I band 32 percent nitrogen and spray herbicides. To have one less thing to keep track of when planting, I installed a push-button starter switch on the planter axle to turn the spray control on or off," says Eugene Alt, Audubon, Iowa.
"There are several locations where you could mount the switch - on a hydraulic cylinder or any other mechanism that will move when the planter is raised or lowered and that will hold in a fixed position.
"The switch should be activated by a spring so it will maintain constant contact. Once the switch is mounted, unplug one wire at the control valve and extend the wire to the switch, and then run it back to the control valve. You can still shut the sprayer off from the cab.
"I side dress nitrogen with the cultivator so I mount a similar switch on the 3-pt. hitch as well. You could use the idea on any field cultivator, disk, or other equipment where you want to shut off an electrical device automatically when the machine is raised or lowered."
