I had had a Case 450 skid steer for many years. It was good when it ran well, but it was something of a maintenance pig and when it needed fixing it was pricy. The local on-call guy out of is truck was $50/hr. plus a service call. The dealer mobile service was about 25% more. To have it picked up by the local dealer was $3.50/mile each way plus shop time at $85/hr. These things are complex gadgets. In the year before I swapped it for a new batwing bush hog I dropped north of $4000 trying to fix an electrical gremlin that never got fixed by either mobile repair services or in the shop. I was happy to see it go.*
If your ground is dry they can do quite well. If you get a lot of rain you had better be VERY careful where you drive it because it can dig itself a big hole really fast. I didn’t have tracks but my neighbor across the street does. He’s come over to help me and is very careful about where he goes with his tracked machine.
These things have very narrow wheel bases and if your ground is hilly you had best be very careful. Another neighbor has gone over in his a couple of times and now is much more conservative.
On the plus side not only can you lift relative large weights you can also get front-mounted equipment that can be very useful. My tenant has a small skid steer and has rented a combination brush cutter/stump grinder that will pulverize light brush and is a whiz at clearing line for a new fence. A $125/day rental fee will do the work of a half dozen men with chain saws, brush blades, and a chipper. BUT given our often wet and always hilly terrain there are many places he can’t go.
On balance, for most ag uses, you’re going to be better off with a tractor/loader combination. If your current tractor has sentimental value buy another tractor with a loader. Pick a model (not a Case 450) and spend some time on Iron Planet, Fastline, or Machinery Trader comparing prices. The compare an equivalent tractor/loader. The skid steer might be a bit less money but will be less capable and potentially a lot more to fix if it breaks (which it will because these things are electrically and hydraulically quite complex).
My advice: pick a tractor/loader combo.

*I swapped it to a Bush Hog dealer. I’ve seen it a few of times in his equipment yard since then as I do other business with him. The first couple of times it was working. The last few it’s been sitting in the same place in the yard. I think I got the better end of that trade!!!
