There is a 3-4 year old Kubota B7500 HST with a 4' bushhog, LA302 FEL, and 60" mmm. The tractor is showing 320 hours. It has been kept in a drive-in shed over these years and shows what I assume to be normal wear and tear. It runs very well from what I can tell. (Remember, I am new to all of this.) This is my first tractor purchase. Money is not falling off trees for me and I just want to make sure I am paying a fair price. They are asking $11,000. They have said it cost $17,600 all new. Based on my description and assuming the tractor and implements are sound: #1: Is the price fair?; #2: Should I have it looked over by the local Kubota dealer, sort of checking out a used car before purchasing? Any/all replies are appreciated. Thanks in advance.
