Hi, I hear from you folks that an ORC is something to have for brush hogging.

Is this the adapter that makes the pto of the hog fit to the tractor pto?

What does the ORC look like, any pics?

What should I look for when I go to buy one?

Is Quality Farm ok to buy from for this or should I go to my New Holland dealer?

Anything else I should know about a ORC?

Thanks for all the good Hog saftey advice in the posts...I have run the 5' hog for the past two years on the 8N in 3' high briars, weeds and such and I have been safe about it...I want to make sure that I have a good set up though. So far I have found that it is a lot less dusty to hog when things are green and not brown, aobut three mowings a year keeps the weeds and any tiny trees trying to grow in check, sometimes it's best to not mow the full 5' at once, and I never try to mow someplace I haven't walked a few times...also I carry a cell phone and have a friend a good distance away with a pick-up and watching over, just in case.

Thanks guys.

As has been mentioned here before, remember to check the PTO shaft on the Brush Hog to make sure it isn't too long when the ORC is installed on the tractor. When my father-in-law got an older FNH Rotary Mower he installed an ORC on his 8n (wise decision). However, he didn't check that the PTO shaft on the mower would telescope in far enough when the mower was in the raised position (the ORC adds a few inches). After raising the the mower a few times, unknown to him, the PTO shaft drove the ORC into the PTO seal and bearings on the tractor. This caused all the trans/hyd oil to drain out of the tractor. Luckily, he stopped mowing before major damage was done. Also luckily, the damage was limited to the tractor's PTO shaft, seal, bearings and ORC. It was repaired with a new PTO shaft assembly and ORC. An expensive lesson.

Dave, the pto shaft from the my hog slides in and out (shorter or longer as needed) so this won't be a problem for me since it 'self adjusts' when its raised and lowered. Right?

don't assume there is enough "adjustment" in the shaft splines to compensate for additional length of ORC

also, there are two possible PTO shaft diameters. Could be either original 1 1/8 inch or lots have been converted over the years to 1 3/8 inch

a couple of minutes of measuring will save hours of grief in both cases

your mileage may vary

Don't forget to take the same amount off each side of the PTO shaft, if it needs cutting.

Measure with the PTO shaft in it's shortest position - usually parallel with ground. Then measure at it's longest - usually with implement fully raised, or raised to where PTO shaft hits implement. The difference between these two measurements DIVIDED in half is the amount to cut off each side of the PTO shaft.

REMEMBER!! measure twice (or more, in my case :-) CRS you know!) and cut once.

Hey Ed - Nice website link. I wish the instructions would have been that clear when I bought my ORC!

SAL, An over run clutch is not the adapter to change your pto size but a safety clutch that will not allow a pto driven implement to propell the tractor when you stop the pto. In other words it allows your tractor to drive the brush hog but will not allow the brush hog to drive the tractor. This is very important when you decide that you need to stop in a hurry! I personally think that every n should have one, but as to where to get the best one, I'm not much help. I'm sure that you will get that info in a later post, as there are several folks on this site that really push for safety when hoggin, and can tell you all you need to know and them some, (really bad stories) about pto safety. Hope this helps
Ron
