Abstract: A device is disclosed for grinding reel type mower bedknives and blades of rotary type and reel type mowers. The device is capable of manually relief grinding reel blades on an intact mower, and in various stages of disassembly, to a bare reel stripped of its housing, with virtually any relief angle. The device can manually and semiautomatically spin grind a reel type mower reel while the reel is attached to the complete mower or if the reel and supporting structure are removed to a bench, with no further disassembly required. The device can manually grind the front face of a reel type mower bedknife while the bedknife remains attached to the reel housing and can grind the front and top face of a bedknife when it is removed. It can also grind rotary type blades and a variety of other straight edged tools.

Abstract translation: 公开了用于研磨卷轴式割草机床刀和旋转式和卷绕式割草机叶片的装置。 该装置能够将完整的割草机上的卷轴刀片手动地卸载，并且在各种拆卸阶段将其剥离到裸露的卷绕其外壳的卷轴上，实际上具有任意的角度。 当卷轴连接到整个割草机上或者如果卷轴和支撑结构被移除到工作台上，则不需要进一步拆卸，该装置可以手动和半自动地旋转卷轴式割草机卷轴。 该装置可以手工研磨卷轴式割草机床刀的前面，同时将手把刀固定在卷轴外壳上，并且可以在切除手柄时研磨床刀的前面和上面。 它还可以研磨旋转式刀片和各种其他直边刀具。
