Mower for Mowing Around Fence and Railing Posts

摘要

A mower assembly is provided for cutting around a post. A support structure supports the mower assembly in cantilever fashion. The mower assembly includes a plurality of mower units with each mower unit having a rotary blade. Two or more mower units cooperate to engage and cut around a post and, during the process, the entire mower assembly rotates about an axis enabling the mower units to encircle and efficiently cut grass and other vegetation about the post.

1. A rotary mower system for mowing around a post, comprising:
a support structure; a rotary mower assembly secured to the support structure and bodily rotatable relative to the support structure, the mower assembly comprising:
i. first, second, third and fourth mower units with each mower unit having a rotary blade;ii. the first and second mower units being moveable relative to each other and moveable between a closed position and an open position wherein in the closed position the first and second mower units lie relatively close to each other and in the open position, the first and second mower units are spaced apart such that the post can pass between the first and second mower units as the mower assembly is advanced;iii. a biasing structure for biasing the first and second mower units towards the closed position but permitting the first and second mower units to move from the closed position to the open position in response to the post passing between the first and second mower units; andiv. the third and fourth mower units being moveable relative to each other and moveable between a closed position and an open position wherein in the closed position the third and fourth mower units lie relatively close to each other and in the open position, the third and fourth mower units are spaced apart such that the post can pass between the third and fourth mower units;v. a biasing structure for biasing the third and fourth mower units towards the closed position but permitting the third and fourth mower units to move from the closed position to the open position in response to the post passing between the third and fourth mower units;vi. the mower assembly including the first, second, third and fourth mower units being bodily rotatable in response to two of the mower units engaging the post such that as the post is engaged, the mower assembly bodily rotates such that at least two mower units engage the post and cut grass or other material around the post as the mower assembly bodily rotates; andvii. wherein the mower assembly when cutting around the post bodily rotates approximately 180° such that the mower units, formerly assuming the rearmost position before rotation, now occupy the forwardmost position after rotation.
