You are getting into some higher end tractors in order to get those listed tasks done. I know the 6xxx series Deere would be an excellent choice but be prepared to spend in the $50,000 range. You can go to a farm sale or consignment auction and get something less than 10 years old for less than half that amount. A dealer is also going to add a few thousand (usually) that what you would pay from a private individual. It also depends on what part of the county you come from. Here is Illinois there are thousands of good used tractors available at any given time, that inlcudes sales and dealer inventory.

Good luck, I know about trying to farm with junk, I have been working around broken machinery for all my life, however, I try to keep my tractors in good repair. I did buy a new John Deere last fall, that was the first brand new tractor this farm has had since 1976.
