A chipper would be freaking nice. I would probably charge people if I had one. I would be able to buck up tree, take all the cuts for firewood, then chip everything else. A one man yard cleaning machine.
Hope this doesn't sound racist but you sound like a modern day Native American. I love how they would use all parts of an animal. The meat for food, fur for clothing, etc. Really resourceful.
I do have that philosophy. I also really dislike wasting fuel, hence why my ratsun diesel pickemup is my DD, not some giant fuel guzzler, and I scrounge whenever I go into town, pallets and so on, scrap produce, whatever. have a circuit I run.. And so on when it comes to energy. The only thing I am wasteful on is this cabin where I live, but I don't own it, so I try to make up for using the wood by burning smalls with mediums and large split wood. Haven't burned any propane for years.
I learned to take small wood when I first burning a lot to keep warm in maine and cutting with a biodrive bowsaw. You don't waste a twig. And you never go away and come back into the yard without a detour through the woods and drag a downed branch back with you. Adds up.
Here's some pics, not done yet, but decent, one tank with the husky 137 First shot (in the shade) of the tops pile, then some progress shots. When I am done, daily as I walk the dogs I drag the leftovers out in the field, next summer, go over with the bushhog, they disappear. I've done this same swampy area several years in a row, you can't see a single leftover branch anyplace. Basically moving the edge of the woods back.
Normally, I do all the tops *first* when I fell a tree, but wanted to drag some splittable big pieces up for the leveraxe deal, and was worried about fall rains and access. So, I cut the tops off and left a mess. It is much mucho easier cutting smalls when the branches are still held by the main tree. Big saw, fell. Set it down. Grab small saw, cut small branches, drag little brush out of the way. Medium saw, finish bucking the branches and now everything you cut needs splitting. Back to big saw to buck and noodle if needed the main trunk. That's how I usually do it anyway. I'm not done yet down there, but brought back a nice load and you can see how the brush pile just shrinks and shrinks.
