Small Engines (Lawn Mowers, etc.): PTO Clutch, blade sharpening, cutting blade

Question
Eric - I have a 1994 Toro Model 30175 Mid-size Proline Gear Traction commercial grade walk behind mower, serial #491457 with a 44" deck and a Toro 54-3200 PTO clutch that activates the mowing deck.  It has a 14 HP Kohler engine pull start.  The engine runs fine.  A push switch engages the PTO clutch, and there is a 10A fuse that blows a few seconds after blade engagement.  I cannot find any bare wire shorts and think the PTO clutch might need replacement.  What do you think?  I have limited tools and abilities beyond oil changes, spark plug replacement, and cutting blade sharpening - is this something the average guy could fix?  Thanks for your help!  Moe

Answer
You could just replace the clutch but it would be better to do some troubleshooting.

THe link below covers testing the electric PTO. The manual is not for you specific mower but the clutches, and their operation, are almost identical.  About the only difference you will find in the clutch are the mounting configuration and maybe some small resistance differences.  I would check the clutch resistance and current draw.  If these values vary a lot on your clutch then I'm betting it is bad.
