I currently own all AC tractors but am looking at buying a 1755 with a cab for blowing snow.  It is a really clean tractor with 4300 hours,  good rubber, factory cab with AC and its a diesel.  The owner said he had the pto worked on at one time and it will not disengage and quit running.  Does anyone know if it is a fairly easy fix or is it going to cost a lot.  I am new to this site but would like some input if anyone is willing.  He wants 7750 for it,  but it is a really clean one owner tractor.   Thank You.
