twin520 0 #1 Posted 4 hours ago I'm in the process of re-powering 520HC with Predator 670 v-twin. Looking for input regarding what specific electric PTO clutch others have used and where to get it. I have the crankshaft bushed out to 1 1/8" diameter, the tractor drive pulley mounted and up to 2" of free crankshaft and with the 1/4" key-way. Also note the main load is the 60" mower. Thanks for your help. Twin520 Share this post Link to post Share on other sites
