I'l start by admitting that I know NOTHING about sickle mowers. A friend mows maybe 30 or so miles of horse trails with his Farmall cub for a riding club. He's been having to cut back the sides with hand hedge trimmers and loppers. He mentioned that he's thinking of buying a gas powered hedge trimmer to speed things up. This got me wondering if a sickle mower on my 1976, 1614 could accomplish this task. How hard is it to find a usable sickle mower for a PK at a reasonable price? Can a sickle be operated with the bar vertical? Does anyone think that it would work and be a better option for clearing the vertical sides of the trails?
