I'm in the market to buy my first used bobcat. what i have planned is to use it around the house and getting side jobs grading and clearing property.my main question is what size bobcat to buy.my budget is limited to $12,000 for the unit. I'm looking at a 873 that looks to be in decent shape but do i need a big machine like this or could i get away with a smaller machine like the 773? Any input is appreciated. Thanks
