Help disconnecting brush cutter

[michehembr]

Hello All,
I have the issues of not knowing how to disconnect my brush cutter from the PTO. I have pulled back on the spring loaded section of the shaft ( circled in red in the attached picture) but it still will not disconnect. I hope some one out there can tell me how to do this. I just bought a grade blade to grade my drive way because its getting bad from all the rain and I cant even connect it because I cant get the cutter loose. Please help.

Thanks so much,
Mike

Hi Mike. Your picture didn't come thru, but what I'd try is while pulling back on the spring loaded section of the connector, try tapping on the edges of the connector in an outward direction, with a light hammer. Occasionally mine will stick and I will try realigning the shaft by slightly lifting the mower or using the hammer technique. Good luck

Thanks I'll give it a try. I don't now why the pic didn't come thru even tried to post it again and still nothing. Anyway thanks Ill give it a shot.

You also have an ORC, but try spraying some PB BLASTER up into the coupler first for a few days. Often when these are left on for long periods they tend to stick. Be sure the PTO shaft on the mower is lubed with grease so it slides freely.

Take the 2 zerts out of the ORC and knock the pin out of the inside. Deal with the other end later.

Try raising your mower so that it's shaft is on an even plane with your PTO. When you pull back on that collar will the shaft move forward at all? Or is it just stuck in it's place?

Thank you for your post but i do not know what a zert is nor do I know the acronym ORC so you have me at a disadvantage. Sorry.

A zerk (not zert) fitting is a screw in grease fitting invented by Oscar Ulysses Zerk (aka Oskar Zerkowitz) in 1924.

ORC is an acronym for over running coupler (or clutch) which is the one way drive mechanism the sleeve on your cutter connects to. The ORC prevents inertia from the spinning cutter blades from back feeding the PTO and pushing the tractor when you clutch. It is pinned to the tractor PTO shaft with a roll pin installed under the two zerk (grease) fittings.

The quick connect sleeve on your cutter is simply gummed up / corroded and stuck to the shaft on the ORC.That is a pretty common occurrence with machinery left sitting for a long time. Pull and hold the release sleeve back while prying or tapping rearward on the body and it should come off fairly easily.

If you happened to go trough a ditch with your cutter, and completely collapsed (Slides to shortest length) the telescoping PTO shaft so it couldnt collapse any further, but it tried to go further....the balls in the disconnect will push on the splines and dent them. the dents will push outward onto the coupler splines and cause the splines to seize. If this happened you will have to pound the connection apart and file the dents down flat again. I have had this happen a time or two on very uneven ground.

It does not look like the grease fittings in your ORC has seen any grease lately. They need some grease time to time.

Actually you should grease the ORC every time you use the mower.

Like I said michehembr, remove the ORC, you don't WANT or need it on the PTO shaft if your going to use your blade. And hopefully you have a screw in cap to put over it where it protrudes from the tractor.

And a big thank you to the Hokie Correction Police
