    I have only found 1 fuse in the system , and it is a 30 amp fuse.

    OK, What you need to do is adjust the PTO clutch and see if that doesn't solve the problem. As they wear the air gap gets wider and requires more amperage to keep it engaged, Which could cause the switch to over heat.


    There is three slots in part # 5 to insert a 0.012 feeler gage and adjust the three nuts until you feel a little drag on the gage. But only move each nut a little at a time because one will throw the other out, Go around the clutch a couple times to make sure they are even.

    Ok, what i found was ,the pto clutch was completely shot. The bearing just fell apart when i took it off,and the coil was all chewed up. Really suprised it ever worked.I also found a few other problems when i was into it. The muffler was trashed internally(glad i saw that one in time). An idler pully, a few bearings and of coarse another pto switch. Ran my tractor for a few hours today and it runs like a top. Thanks for help yall, great forum!
