AlSAmcastar Farming, Saturday, August 16,1986 NEWARK, Del. - The hum of forage harvesters chopping the ‘BB crop has already begun on Delmarva. “Keeping knives sharp and adjusting the shear bar is the key to harvesting silage ef ficiently,” says University of Delaware extension agricultural engineer Tom Williams. “And keeping hands and feet out of moving machinery is the key to harvesting safely.” Williams recommends shar pening the knives at least once a day - more if the forage is ex tremely dry. “Every time you sharpen the knives, adjust the shear bar to the minimum recommended clearance,” he says. “Doing this can cut fuel costs hy up to 30 percent. When the center of the bar wears beyond the clearance limits, reverse it to expose a new edge, or replace it with a new bar. Tungsten-coated mes wear more slowly than other types." Since the time spent sharpening and adjusting shear bars is made up for in improved cutting and lower fuel consumption, it pays to notice when the load on the engine seems to be increasing. That means it’s probably time to resharpen. Hydraulic or electric knife grinders and simplified shear bar adjustments make it easier to keep cutters in top shape. “When sharpening, it isn’t necessary to remove every nick and dent, but it is important to grind the entire length of the knife,” Williams says. “Grinders that can’t sharpen the ends make minimum clearance adjustments impossible in the center of the knives.” The length of the cut also affects fuel and power requirements. Going from a half-inch cut to a quarter-inch cut will increase power requirements by as much as onethird. “But energy isn’t the only factor to consider when choosing cutting length,” the Forage Tent Activities Announced This year at Ag Progress Days events at the Forage Tent include: • Pennsylvania Hay Show- up to 30 classes of hay will be Judged on Tuesday, August 19. Samples should be brought in before 10:00 a.m. on that day. If you would like to participate, contact your county agent for entry forms, rules and regulations. • MIR Van - the van will be available to run analysis on any fanners samples that are brought in. Also, we will have the complete program available for balancing rations. • Living weed and forage plan display - examples of many weeds will be on display. You can also see a living display of common forage plants. Penn State experts will be on hand to answer your questions. Think Safety When Harvesting Forage engineer says. “Also consider storage quality in the silo, the limitations of your handling equipment, and the effect on livestock feed intake and production.” Forage containing 65 percent or more moisture can be cut a half inch long and still store well. Sixty percent or less moisture in silage needs finer chopping to pack well. Also, silo capacity and handling capacity are reduced when silage is cut longer. Under most con ’ ditions, Williams says, quarter- to half-inch cuts produce excellent silage or haylage at a reasonable energy cost, but chopping finer than that is undesirable. The engineer also stresses the need to take proper safety measures, particularly when sharpening knives. “Wear eye . protection - especially if you have to remove any shields. Keep your hands, arms and head away from the opening, and don’t let anything fall into the knives,” he warns. Block the cylinder cutterhead when replacing or repairing knives, so the knives can’t move unexpectedly. Because the knives are free-wheeling and continue to move after the power is shut off, it may be tempting to stick a broom handle or stick into the knives to knives, or chips of wood can be Tiring them to a quick stop. thrown back at you. Always let the "Don’t do it,” warns Williams, knives come to a complete stop on “Your hands can be jerked into the their own.
