I have a craftsman 6 speed riding mower with a kohler pro 22 v twin motor. I was able to get it started today (had to clean carburator) i drove it approximately 200 yds to my grass area to begin cutting like i always do, put clutch in engaged blades lowered blades and when i let clutch go it wouldnt move in any gear! I tried everything to no avail even the range shift lever? I cant believe that the transmission or clutch went out on me after it was moving fine in all gears, but i fear the worse.
