Alamo Bush Hog BH300 Series Operator's Manual page 119

Operating the mower with loose blade hardware will damage the blade holder or blades and
can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown
out from under the mower for distances up to 300 feet. When the blades are replaced, the
fastening hardware must be replaced. Check and retighten the blade hardware after the
first eight hours of operation. In severe cutting conditions, recheck the blade carrier and
blade bolt torque every 50 hours.
To help prevent structural damage caused by loose hardware, tighten gearbox mounting
hardware as specified. Check the fastener torque after first 8 hours of use and every 50
hours thereafter.
