Got me a free STX38 question about PTO clutch.

Hey my neighbor brought his stx38 to the shop because the electric clutch wouldn't engage. The shop stated that he needed a new clutch and the estimate was around $300.

My neighbor ended up buying another unit so he gave me this one. Ended up looking it over tonight and I noticed that the PTO indeed wont engage the blades.

I get no indication from the switch that it's working ( no noises ) so I started looking at the clutch itself...when I disconnected the plastic connector from the PTO I saw three wires two (2) that run up towards the hood cover...the other (not the same color but forgot what it was) runs about 4-5 inches and is left hanging.

The wire is stripped of it's insulation at the top leaving around 1/2" of the copper exposed.

Is this how it should be or should this wire be connected to something like a ground?

I'm going to look into the clutch further at a later time...I only had about 30mins to spend tonight.

One more thing...if it turns out to be the clutch how hard is it to change?

I only saw one bolt on the bottom pulley under the PTO and was wondering if I just remove that bolt and pull the whole assembly out. I'm not really sure how the clutch is mounted on the shaft.

Thanks for the help.

Thanks for the information thus is black deck. I'll look into the diagnostic later in the week.

Does anyone else have three wires coming from the PTO connection with one not hooked up to anything?

Thanks again,
