PTO tripping main fuse after a bit
 

2084 Super. I'm not good with a volt meter, but from what i have been reading on here I think I have a coil issue. The lawn mower (engine) will run all day with pto off, maybe a minute with it on. I removed the belt to rule any drag problems and it still blows the fuse in the same amount of time. It has been doing this enough over time that I replaced the 20amp fuse with a 20amp breaker so I could reset it, as it would blow once or twice a mow, but now...
As a side note the blades and the motor have been bogging down occasionally like it was in real think grass before spinning back up to normal. Deck is clean and greased and spins freely, so would that also point towards a pto issue?
Thank-you

Need more info, like the model tractor that you have? :Unknown:

Sorry, I thought it was in my sig. It's a 2084

(A) What coil are you referencing...???

(B) You mean the engine...??? :Huh:

the coil in the pto clutch. I was reading that it can short out and blow the fuse, or a issue with the assembly will cause it to draw to much power and short the fuse.
And yes, i meant I can drive the mower around the yard as long as I want if I don't have the pto switch engaged.

OK sounds like the PTO is getting tired. Blowing the fuse means you have an electrical overload. The blades slowing down is also an indication that the PTO is not fully engaged and it may be slipping. That said you need to check to make sure that you don't have some other electrical issue. If it turns out that the PTO is done give these guys a call, yes I said CALL, they can build you a newer, better style replacement.

Check the front crankshaft seal to make sure it isn't slinging oil up on the clutch and making it slip and overheat.

Also wires get rubbed/frayed/shorted to ground along the way from point A to point B.
It would not hurt to inspect along the path, as well as connections @ the PTO switch/relay and ign switch.
I'd start @ the clutch and work back to the power source, it sure don't cost anything to do that. :beerchug:

I did clean the mower exceptionally well looking for leaks and checking the wiring. Everything looks ok. The main wires that go to the 20a fuse are extremely hot after it blows/trips, so I am leaning towards something drawing way to much load.
Thank-you everyone for the suggestions, I did see xtreme referenced in another thread, so I will give them a call as soon as I can get the old unit off.
Do I need to remove the whole front end or just the grill?

On the harness from the PTO clutch, is there 1 or 2 wires? A friend of mine had a 1572 Cub Cadet that was causing the breaker to trip every time the PTO was engaged after a short time, the same as your 2084. I went over his house to troubleshoot it with schematics in hand. The schematics show one side of the coil being supplied with +12V while the other side is grounded. Initially I thought the ground was supplied via an internal connection in the field coil, but when I saw 2 wires going to the coil, I put a meter on it and found that one wire had 12v and one wire was grounded. I figured if one wire is grounded and one wire is supplied with 12V, BUT the +12V wire is grounding out and blowing the breaker, why not switch the wires in the connector going to the PTO coil. Put GND on the wire that is grounding out and +12V on the one that WAS supplied with ground. With a simple pick, I pulled the wires out of the connector 1 at a time after marking them since they were both black, and reinserted them with the opposite polarity. It worked like a charm! The PTO worked flawlessly without tripping the breaker or drawing excessive current AND HAS continued to do so for 4 - 5 years since we tried this out. Of course your results may vary.....
