A skid steer has been the best investment i have made. My tractor is now a trailer tow vehicle most of the time. Its main function is now watering trees with a pto pump with a trailer that holds a ibc tote.
The skidsteer disturbs the ground, but this can be a positive. If you dont have a mob herd grazing, the skidsteer becomes that. If i work an area, the grass is gone. I throw seeds out and call it good. Mine doesn't have tracks. I couldnt justify the extra expense and heard stories of tracks getting thrown from normal stuff like like driving over a rock or short stump.
These are things i have used it for:
Loading/stacking round bales of hay
Clearing trees and removing stumps (no chainsaw, just pushing them over and out). I don't remove mature trees which it probably would not do.
Digging swales and water retention holes. some as deep as 4ft.
Digging out large rocks
Use it as a scaffold to repair roof (someone lifts me up)
Made a creek channel into my pond. Basically made a "finger" that Paul suggests.
Spreading
compost. Dump on ground. Set bucket 1 or 2" above ground to spread it evenly. Woodchips also but not as good cause they clump together.
Dug a trench for a water line with a stump bucket.
Forklift loading and unloading
Skin deer.
Bury a dead sheep.
Theres much more.
The amount of soil it removes compared to a tractor is amazing. Same with clearing underbrush. Its a beast. People say if you have a tractor, you will use it(get one, you won't regret it). I say if you have a skidsteer you will use it more. It digs, it pushes, it works its ass off. I did in one hour what it took me 10+ man hours to do just in clearing brush.
I have no knowledge of equipment "besides " the skidsteer. Travis should.
If i had to get rid of one of mine, it would be the tractor. Google skid steer attachments. You'll be amazed at what you find available. Many of which can be its own side business. Shredding, digging post holes, trenching, etc. Each attachment is an expense.
