I have a bid in to a guy to clear a small bank above a pond. its overgrown with brush, a few briars and a few small trees about 2" in diameter. the hill is fairly steep but it's not too big. I originally was thinking id go in with a chainsaw and then pick up a brush blade for my stihl FS90. then, it came to me......go rent a walk behind bush hog. The local rental outfit has what I believe to be a Billygoat walk behind brush mower. If I'm able to just mow it, it should take around an hour, but only because the bank is so steep. it's also $75 bucks a day to rent this little guy. I haven't priced the brush cutter from Stilh yet but I'd expect it to be about the same as renting the brush mower, but more of a pain to use. my question is for those of you who have used a walk behind brush mower, are they fairly stable on hills and can they hack through 2" saplings? the hill I'll be dealing with is right at the threshold of being able to get a normal walk behind mower on. If the Billygoat is sure footed enough, I'll just mow everything, take out whatever the mower can't get with a saw, rake everything up and haul it away. I bid this two ways, both with and without stump removal. the guy just wants it mowable and is fine with leaving the stumps cut clean with the dirt. so if he wants me to do it, I'm not planning to have to grind any stumps, even then, anything left will be fairly small-ish. I also gave him a price for weekly mowing so I gotta make sure the stuff is low enough not to tear up my machines when I mow weekly as well. I know I'll have some hand work to do afterwords. If these things slip and slide on a side hill, I'll pick up the brush blade from Stihl and do the some grunt work. I have priced it accordingly and should make a few bucks if I get the job. I've accounted for rental fees/equipment purchases as well. So what do you guys think of walk behind brush cutters?
