发明名称 Rotor blade door and method
摘要 A convenient user-friendly method to sharpen the rotary blade of a rotary cutter assembly without having to turn the rotary cutter assembly upside down. To this end, a rotary cutter assembly is provided with a special access door which is preferably securely fastened and/or locked during cutting and use of the rotary cutter assembly. When it is desired to sharpen the rotary blade, the door is unfastened and opened to permit access to the rotary blade. The rotary blade can then be clamped or otherwise secured and subsequently sharpened with a grinding wheel or other sharpening tool.
