I am new to this and I just started my own lawn care business. I have the chance to buy one of the following and I need 'ya'll's help on pricing/values, ect---1.)Oliver 500 w/2321 hrs.-running when parked 2 yrs. ago. 2.)Ford 4000 Select-O-Speed with 2539 hrs.-running when parked 2 yrs. ago. and 3.)Ford 3910 Diesel with 964 hrs. It also has front and rear hydraulic hook ups on it-still running. My uncle had a farm and he died 2 yrs. ago and this stuff is still sitting there. I would like to be able to bush hog, use a snow blade and grader box. Any help would be appreciated. Also, would I be able to pull one of these with my truck-it's a 97 GMC 1/2 ton 4X4 with a 3.73 rear, 305 cu.,8 ft. bed and a five speed trans. THANKS.
