Andy I checked your profile to get an idea on the land you own, such as where you lived which would give many here a very good idea, and also wanted to see how old you where, which would give us an idea on your physical condition, but you don't have any info.
I am 47, clearing 13 acres of northeast mountian land, cutting and burning all softwoods, and saving the hardwood, also removing rocks and such. Its good excersise and may add years to your life, there is also no where else I would rather be or doing...
18 Degrees, Coyotes Howling in the distance, no one around for miles, and an all day fire, no where else I would rather be on a nice winter day.
All I can say is give it shot and see how ya make out doing it yourself, the tools you purchase you will more than likely need to maintain your new spread...take it form there. Now is a good time if there is no snow, no ticks in many parts, buring in normally not an issue this time of year, and the scrub brush does no have leaves and critters,making it easier to carry as allthe moisture is in the root ball and they are domant, not to mention there is not much a s s time, cause once ya sit down, ya get cold, its time to go back to work then....summer is another story in my book for land clearing . just pack a lunch and make it a day, you'll be surprised at your progress.
