I'm going to add my rambling two cents. I have 26 acres of mostly Lodi silty clay loam. When I bought my farm I hacked at the overgrown fence lines with a variety of billhooks, hoes, machetes and a pushmower. It took me a year to clear 1000 ft of old barbed wire fence that was encrusted with all kinds of fun poison ivy and rose. My back still hurts. I lugged the chopped up barbed wire pieces to a central location as my own draft animal. The work was demoralizingly slow but felt good on the soul. I wanted to key line my property and spent the entire first two years shopping for the right tractor while doing everything manually. The two years was crucial to figuring out what I needed. Not that I got it perfect but it helped me understand what my needs would be. I needed horsepower to key line with a plow (I wound up with a single bottom plow that works great for swales). I needed material handling to really get the work I wanted to do, done. I needed to dig ponds for surge protection at the ends of my swales. I needed to maintain roads and create new ones. I needed to brush hog the property lines and the roads to maintain their access, additionally I needed to maintain any brush work I had succeeded at and go further on those old barbed wire lines.
I bought a 50hp 4x4 JD 4700 used as hell. It had 3000 hours on it when I bought it from a third tier dealer who had purchased it at auction from a Graveyard. It had been a gravedigger. The platform was factory mated with a backhoe and that is what sold me on it. I immediately sent it to the JD dealership to fix old hydraulic lines, and to get everything back into field ready condition. It cost me $20k used and I put another $2500 into it with repairs and a replacement tire.
Pros: Big enough to do almost everything I need, more so usually. I can put the backhoe on and haul as big a scoop of topsoil as I can grab in the front end loader without worry of toppling. I can mow with my backhoe and it looks like finish mowing, I can tiptoe around all of my obstacles and manicure my land decently. I can dig 8 ft down with my backhoe and grade decently with my front end loader.
Cons: My neighbors will hay my fields if I ask, but the tractor can't safely carry the roundtables, they're huge and it just isn't safe. It can lift them but I'm not comfortable. I occasionally regret not going with the larger platform JD that has the same size wheels front and back, they're more competent in the field. The backhoe option meant that the tractor didn't come with a 3pt hitch setup, this was a much bigger problem than I dismissed it as being when I bought it! 20 year old parts matching isn't straightforward and is damn expensive. Being old, my tractors joints are all loose. I didn't realize it but every front end loader and backhoe joint wiggles and sways in an unproductive way. That being said, I save 20k off new.
Some thoughts for those contemplating buying a tractor. I wish I had a BCS also. I have a high tunnel and this tractor is not appropriate for it. I mow with my zero turn now that I've tamed the land with my 4700. I would not want to be without the ability to jump in and go dig a hole, or scoop up something, or grab a telephone pole out of the ground, this capacity has helped me turn motivation into action. $25000 is a ton of money. I took out a 4 year loan to buy it. I was able to pay it off early but it was $400 a month and that was not easy on top of everything else. $25000 would have gotten me 1/6th of the way to paying off my farm. This was a serious tradeoff in time for debt. My tractor could be slightly bigger. I thought I was buying too large, I wasn't. I could easily go back and decide to buy the same HP but larger platform JD, the functionality would have paid off and the prices were similar, I was just intimidated.
Hope some of this helps someone.
