Most of the smaller Compact Tractors will do a fine job especially if You get one that can be put into 4-Wheel Drive,a 35-50 HP Tractor can get into smaller areas and be a heck of a Work Horse,front end loader attachments are nice also!
I've been looking at the Kioti Tractors and Mahindra Tractors,most are from around $10,000.00 to $15,000.00 range and higher if You get a bigger HP engine or an Hydrostatic Transmission compared to a manual Trans!
