ToyLC: I am a retired engineer with a farm similar in size to yours. I have two tractors with front end loaders, one two wheel drive the other a 4 wheel drive, a JD 490E Excavator (which I would not recommend to anyone, the first generation computer controls are a PITA) and a JD 644 loader. The ownership of heavy hydraulic equipment is very expensive maintenance wise. Something is always breaking, leaking, wearing out or just plain failing. I have owned other equipment like a new CAT TH-83 telescopic boom, and multiple 4 WD backhoes. Heavy equipment in the price range you are seeking for the service in my honest opinion I would not recommend. You will invest more in time and money than you will ever recover on resale. The most versatile, reliable and useful machines for your purposes in my opinion would be a good 4 wheel drive backhoe, a good long chain and two good chainsaws. Cut the tress off at the stump and drag them out with the hoe bucket and chain, then cut them to size and transport them to storage in the front bucket. The front bucket will also be useful for stacking and pushing debris piles. Many dealers offer a lease or rent to own with a minimum 1 year term. They can be rented monthly with the option to convert to a lease to own later, applying the rent to the purchase price, or simply have the machine picked up. Lease payments are normally significantly less than rentals. Backhoe's in my experience require little other than ordinary maintenance. Heavy hydraulics and track systems can cost 10's of thousands with one breakdown.
