We went with LS tractor, and 2 yrs later we’re still very happy with it .Great tractor, great dealership.
Seriously, just get the rotary mower – it’s not that expensive, can be stored outside under a tarp, and often the tractor dealer will include a heaviy discounted mower it in the package. I wouldn’t rent-- you’ll spend more in time and delivery costs than it’s worth. Bush hogging isn’t limited to cutting down wild overgrowth - we use ours to mow our very well-maintained pastures. But yes, it produces a “field cut” or “rough cut” appearance. It’s tidy and maintained, but not a pristine golf course kind of look.
An alternative is getting a gas-powered pull-behind mower that you tow with an ATV/UTV. We used a 44" Swisher trailcutter to mow pastures for years until we got the tractor+bushhog. The trail cutter is handy but not as powerful as PTO-driven mower, you have to go quite slow, and the 44" deck means it takes a lot more passes to cover the whole pasture. And in the spring, when you have heavy lush pasture growth, the trailcutter really labors to get through the thick parts, and leaves messy clumps behind that you have to mow over 2x, so it doesn’t turn into thick thatch. The PTO-mower doesn’t so much as blink at that stuff and doesn’t leave clumps behind.
An FEL is essential tool, you definitely want that. And we purchased some bolt-on fork attachments for our bucket (from Titan) that have been a incredibly useful. I use them all the time. BUT, I will probably replace them with a “Debris Fork” attachment, which will let me pick up a wider variety of crap than just the pallet forks. I’ll keep those on hand for unloading trucks, moving large logs, etc, but the debris fork will probably be my go-to implement for property cleanup.
We also got the backhoe attachment with our package, since we knew we had numerous drainage projects and stumps to pull. So for $5k extra, the backhoe has totally paid for itself for us-- not to mention we’re suddenly the favorite neighbor for everyone who needs a hole dug. But it’s definitely in the ‘Nice to have’ category, not essential. Ours is pretty straightforward to put on & drop off, no heavy labor involved. It’s a blast to use.
Warranty isn’t really negotiable, that’s all set by the manufacturer, and they’re pretty standard across the various makes, if I recall. More important, as others have said, is that you have a dealer within economic distance to get it serviced.
Insurance-- your homeowners policy will cover it, no special policy riders needed.
