27666 Fisher Snow Plow Headgear HD RD X EZ-V Series MM2 Minute Mount 2

Fisher MM2 Headgear # 27666.

This is a headgear assembly that includes the jack and lift arm. If you want just the bare headgear that is part # 27454. The image shows a silver lift arm but that may also come in yellow we often have them both ways. 

This came in plow assembly kits 27777, 28888 and 28900.

This is used on the HD, RD, X, and EZ-V series snowplows using the Minute Mount 2 system. It is just the main headgear frame.

If you have an LD plow then it would use lift frame 27742.

MC plows need Lift frame # 28571.
