Greetings:

My son recently picked up a really clean John Deere JA65 self propelled push mower with a cast aluminum deck and a 6HP Briggs Quantum engine. It has a Warner mechanically applied blade clutch on it (expensive part) rather than a typical ignition cutoff and flywheel brake as the deadman control.

The engine runs great, but the blade clutch is weak (slips under any kind of load). Has anyone ever tried to rebuild one of these clutches? Looking at an exploded diagram, it looks like it has it has friction material on one of the plates (and two bearings that appear to be replaceable). Maybe that friction material can be replaced? The clutch engagement cable appears to be adjusted properly (applying additional force did not stop the slipping).

Thanks for any thoughts on this.

Double check the adjustment . Price it out and before doing anything, take the assembly apart and inspect all the parts for wear.

Hoping to remove and disassemble the blade clutch in the next couple of days (will check to see if it can be adjusted first - nothing looks obvious so far). Service manual ordered as well. I will report back with what we find - thanks.

Believe it or not, it looks like the cheapest replacement is to go directly to the Warner web site (cheaper than Ebay, Amazon, etc.). They sell their replacement clutches directly. JD is sky high.

Warner blade clutch 5915-17
