Thanks everyone for the awesome input. I have a brush blade that can get through 2" no problem so I've been using that and a chainsaw. This stuff is pretty thick, and very viney, but I've managed to get a good 3' path cleared that's about 60 yards. Pretty steep but it's a saddle and travel corridor so it'll be worth it. Think I'll leave it this season and see how it does. Every farmer here sprays "roundup"/herbicides so if I need to I'll resort to that next season. Thanks again.
I have a large property I bought for deer hunting that I have cut about six kilometers of trails about ten years ago and maintain them to this day. I would like to offer you some advice on some tools to make your trail cutting as easy as possible.
Loppers are your best friend for trimming over hanging tree branches and small saplings. You get a lot of output for very little input, a person can lop a long time before they get tired. Using any tool that you swing like an axe or pull back and forth like a buck saw will tire you out in half an hour, bring an axe and a buck saw for when you do need them but they are too labour intensive for long periods of work.
When buying Loppers buy good quality ones and make sure the pivot point is just one bolt like a pair of scissors, don't buy the ones with the power/leverage arm at the pivot point, they are to slow and don't open very wide.
Also for bigger trees up to a good three inches in diameter you can buy a pair of ratchet loppers, they work great, I picked my pair up at home hardware.
A gasoline powered brush saw is great with a steel saw blade, try to buy/find one that is not made in China and make sure it comes with a shoulder harness to reduce fatigue.
I cut all my trails just wide enough for my ATV so I could pull a harrow behind it, drag out deer and carry things like ladder stands and such through the property.
I hope this advice helps you out, For most of us time is limited so getting as much work done with the least amount of effort is the way to go. I wish someone had told me about loppers when I was first starting to cut my trails.
I actually look forward to getting out and maintaining my trails, the initial cutting of the trails is the biggest job but it is well worth the effort in the long run as you make yourself your own custom hunting property.
