i'm helping my mother-in-law keep up the pond behind her house .i need some guidance on the best way to cut the grass and cattails around the pond.she has a 4wd drive kobota tractor (i can't remember what model 410? with front loader) anyway we have a 6 bushhog ,but i can't get close to the waters edge especially on the dam's bank.would a sickle bar mower work well for this task?i can't seem to find much information on them or how much do they cost? thanks in advance!
