Jumping in late- head to Craigslist or FB Marketplace for a used 3-point mower. If/when we ever get one, we'll go that route. I have a Kubota with a 3-point but we mow our heavy brush with a Billy Goat and use a 52" Snapper Pro with a sulky for the "grass". Need I add my wife uses those and I'm stuck with the line trimmers? Oh, and she's demanding our next PCP is a big-bore, nothing smaller than .35 The .25 Lelya doesn't have the power we're looking for. I recommend reading Manny's write-ups on his Rex bolt+slug throwers. 2 shots in rapid succession, a bolt followed by a slug for coup de grace, though I doubt any pig is gonna survive a 525 FPS bolt We're actually looking currently and torn between the Win 70-35, a Rex in 35, or going with one of the Senecas, but AEA seems to be doing some marvelous things so they're on our radar. Also, keep in mind that just because you can fill to 5000 doesn't mean you have to.
A couple of straw bales or a soft dirt embankment will work for air bolts. You don't want anything solid like wood as the bolt will be damaged.
