Keep sickle bars and rotary knives sharp. Square Balers Always disengage the pto and shut off the tractor before working on equipment. The flywheel supplies a uniform momentum for operating parts and will continue to turn even after the pto is disengaged. Always allow time for it to stop turning before working on the baler. Knotter operation can usually be viewed by a hand turning the flywheel.
Extra caution is needed when bale throwers are used because of potential energy in the unit.
The newer large square balers pose an even greater risk because of the larger tractors needed for operation and the weight of the bales produced. As always, caution is needed when loading bales by hand onto wagons. The experience of the stacker and the person driving the tractor or truck pulling the wagon are important elements for safely loading and hauling wagons from the field. Round Bales Always disengage the pto and shut off the tractor before working on equipment. Stay clear of pickup fingers, rollers, belts, and raised rear gates.
