I use a bunch of tools to maintain 6 mile trail to my 1 1/2 mile driveway to my cabin on 240 acres. We put in the trail/drive to my place and a neighbor’s 80 acre place.
A wildland firefighter’s tool like in the OP is great for lots of work. Mine is a McLeod and very rugged. I also use a 6’ breaker bar and 4’ crow bar for big rocks. Standard pick, multiple shovels, etc. I use a small sharp-shooter shovel with file sharpened edge frequently for roots and light prying. Multiple machete’s, axe’s, hatchet’s. Stihl loppers are fantastic and much safer than running a saw at times- can cut limbs and roots really well. I have 8 Stihl chainsaws of different sizes (I admit I go smaller as I get tired!). Stihl gas pole pruner, Milwaukee elec pole pruner and manual pole saw are great for reaching out. Husqvarna log tongs are the greatest thing since sliced bread for moving limbs/trees that are downed. Come-a-long with 150’ rope is awesome for moving things.
In winter I like my Silky Big Boy, Stihl loppers, Stihl MS261 (great saw and light), Milwaukee m12 hatchet (6” chainsaw), and Milwaukee m18 pole saw.
That ‘baby chainsaw’ looks like a toy, but has been amazing for cutting overhanging limbs when it is icy or tons of snow, by allowing me to safely grab the branch with one hand and control the cut with the other. Really nice not having to start up a gas saw when standing on ice covered trail or reaching from my snowmachine. It rides in a pack against the backrest.
I carry way more stuff than I need going to cabin because I usually travel solo and never know what situations might occur. Trail maintenance is hard work but ver gratifying!
(Almost forgot to mention my old JD dozer)
Good luck with your efforts!
