I'm happy for you.
But I hope you realize you can have a $20,000 repair on a machine that size, overnight.
Simple things like the Hydraulics can cost up to $5,000 easily, not to mention the final drives, Engine, or even simple track pad replacement.
It looks like your area is fairly soft, so I'm thinking the wear and tear will be minimal compared to my area. Solid Rock, I took these pics a couple years ago when I worked for that crooked Construction Company.
