3-Point Hitch Burning Clutch Smell

[the old grind]

...Branson uses a electric over hydraulic PTO, so no need for a clutch pedal for that either...

So yours is HST too and not shuttle?

My CUTs have HST and brake pedals on the same side. :ashamed:

The one whose electrics are failing doesn't have electric PTO. It still works. I trust the foot.

btw does "electric PTO" mean no kind of clutch anywhere? Oh.

"Ya learn something every day."

Mine is a shuttle shift with a clutch but the OP said his was a HST, which don't have a clutch nor a clutch pedal.

The PTO clutch on these tractors is a Clutch pack, pretty much like a clutch pack on a automatic transmission.

Once you flip the switch to the On position, it will activate the solenoid on the valve block which applies pressure to the piston of the clutch pack and therefore engaging the clutch. Once the switch is OFF, a spring pushes everything back and actually presses it against a brake disc. This happens all inside the transmission under a oil bath just above the range gears.

Not really a electric PTO clutch as in the lawnmowers but a electric over hydraulic clutch.

In addition to the PTO clutch being wet, the brakes are wet too. So they would not be making the burnt clutch smell. Either we're down to burning insulation, or your DPF has got some soot in it and you're smelling it burning off. My 3725 does make a slight odor at times, usually after I have been doing something that's low load on the engine. To me it's different from burnt clutch smell but it's not that much different (and it's a new smell from the tractor) so I could see thinking it was like burning clutch. Running the tractor hard for a while makes it go away.

BTW we all thought you had a gear model with a clutch because the 5220C in your profile indicates a gear transmission. An HST cab model would be a 5220CH.

My apologies!!..... Let me start over.

I have a 5220C..it has the 3 ranges on the left of the drivers seat...and 4 different speed options on the right.

A little history:
I first notice the " burnt clutch" slightly last year when I was installing 200 ft of septic lines, using my three point hitch backhoe.....which uses the PTO shaft pump.

A few months later I was pulling a broken wooden fence post out of the ground ( we were hit by a tornado in western Ohio )....I pulled the fence post using the front-end loader...PTO shaft was NOT rotating on this project....and I noticed the " burnt" smell again.

A few days ago I was pulling some very large logs out of the woods...to go to a sawmil ...and noticed the smell again after I was done. I was using only the FRONT BUCKET and mostly REVERSE while pulling these logs.

I hope this helps with any confusion I might have created.

Thanks again

The funky smell of going through regen?

You sure its not just hyd oil smell from the vent .............

 

[Orebonder]

I have actually "smelled around the "back" area by the vent...and nothing seems to smell there...it actually seems stronger inside the cab.

 

[Orebonder]

And mine is the 12/12 HST...5220C...not the 5220Ch

And it says " dry clutch"

That help any?

Thanks
John
