4300 PTO won't disengage.

[defed]

those are the same graphics as on mine, arrabil.

i did a scan thru the pdf manual, and there is certainly many diagnostic tests that require the pto to be either engaged, disengaged, or in neutral.

section 8-66 - pto theory of operation...seems to indicate only on or off...and that the pto should turn slightly when 'braked' to align attachments (which mine does):

A locking tab on the outside of the brake housing allows the PTO drive shaft to rotate approximately 330°, which, in turn allows the PTO stub shaft to rotate approximately 65° to aid in aligning the splines of attachment driveshaft during hook-up.


seems like alot of discrepancy in the documents and labeling of the pto.

Defed, thats the "tractor taking it in the rear" hieroglyphic on ours I'm afraid. The options seem to be sit on it, or sit on it and rotate. I really wish I'd have never seen that sticker.

Took a pic of my 4300, to show the distinct three positions as indicated by the hyeroglyphics.

Interesting!

Although the different trannies offered for the 4300 have different parts
pages for the PTO in the parts book, I can not see any differences. I
compared part numbers for a few key PTO parts and they are all the same.
PDF reader does not let me view the same doc side-by-side in different
windows, so my comparo is limited.

Finally, I went to the label part of the parts book and your label is not in
there, even for the European versions. The only label is the one with
the tractor pic with the rear end arrow.

Searching through the tech manual reveals some interesting tidbits:

Good idea. The electrical service sections are full of these inconsistencies. I
had not looked there.

I searched my PDF version of the OPs manual and all references to the
rear PTO use the designations "engaged/ON", or "disengaged/OFF". I
searched for all "neutral" references and none had to do with the PTO.

The only thing i waqnt to add is that wherever i had that lever "set" was obviously between stopped and fully engaged. I ran around mowing for 15 minutes hals-***** engaged, because my shredder kept coasting to a stop when i got into anything heavy...
Basically i was probably heating up the clutch discs spinning the **** out of them. wheni DID finally get it engaged, the disks were probably hot and stuck/melted together... now they won't come apart. I will answer that as soon as i tear it apart, it rained and i did not want to start tearing it apart where it sits. will do it this week.

thanks for the input all, i will let you know.

boy, we got a bit off topic here, i had forgotten what the original post was until now!

i did a bit of testing today. in the middle position, the mower tries to turn, but since the pto is 'free wheeling', it can't overcome the friction of the drive belt (finish mower). but it does try to turn. i suspect the brush hog will still spin in 'neutral'.
