| Last time out I was not able to cut grass because when I tried to engage the mower blades the machine died.
After a couple of starts and attempts to engage the mower, the mower belt came off. When I re-installed the belt the engine would NOT start. When the key was turned to RUN position I heard a loud click and after a few attempts I determined it was around the mower belt clutch. No reaction from key at the START position. Came in the house to study the service and parts manuals. Checked for continuity in the ignition and in the PTO Clutch Switch - everything checked with the service manual. Checked resistance in the coil on the PTO clutch - 3.8 - nicely between the 3.28 and 4.02 stated in the manual. Page 11-37 on the Service Manual says check out the diodes next. I am not sure where or what these are or how I woudl check them. Would appreciate any experienced direction on what to check next (and how). Trying to save a trip to the shop. Thanks

| My guess would be that in the process of coming off the belt knock the PTO switch out of alignment. With the engine off engage and disengage the clutch and look at the switch. Good luck. |

| Hi Wheel Horse of Course Thanks for the comments. I am not sure what you are referencing as the PTO switch on the Gravely is at my right hand beside the seat and the belt operating the mower is under the machine. On my old wheel horse, the belt was at right hand the side - is that what you were thinking?? Bob |

| ***"I tried to engage the mower blades the machine died.>>>When the key was turned to RUN position I heard a loud click and after a few attempts I determined it was around (in the area of?) the mower belt clutch."*** Without the benefit of a wiring diagram to view, I opine that you may have a defective PTO switch. When the engine died as described in the first sentence above, the PTO switch MIGHT have grounded the ignition, killing the engine. The next sentence above describes a scenario in which the PTO circuit is already energized as soon as the key switch is turned to RUN. Plus the fact that the starter circuit seems to be open (which may also be due to the PTO switch) With a wiring diagram, we could walk through the circuits systematically to determine what was at fault, but at this point, I'm going to indict the PTO switch. |
