I'm having trouble getting my Landpride rotary cutter off the 3 point hitch. I put it on blocks about 8" high, detached the PTO drive and the top link, loosened the check chains, but can't get the lower links to move over enough to come loose from the pins on the cutter. A friend told me to kick them but I don't think that'll do it -- I've got like an inch or two left to go and mild kicking aint doing much. Seems like there ought to more play in the lower links but they seem maxed out. Any suggestions? Put WD40 on everything too. thanks for any suggestions.
