Bush Hog~ Driveline shortening? Argghh!!

Sooner or later, everyone will catch on to the fact that dang near EVERYTHING I say/type is centered around good natured joshin'. (Hence, the )

And it's alright to call me old....

Yeah, I'm up there too (61)...

I have seen some pretty serious agitation on your part though...fairly recently. I have gotten irate too, BTW...same threads.

And ... while your messing around with the PTO shaft SHUT OFF THE TRACTOR.

And don't forget the hardhat and safety glasses, and leather cut proof gloves. And oh lets not forget an MSDS on the lube on PTO shaft. I mean we need to be safe right? :laughing::laughing::laughing:

One remaining question: Why would it be harmful to raise the mower with the shafts installed if the tractor is not running, once the shafts are cut to length? That is the way one is intended to transport the mower is it not?

Just out of curiosity can you raise the mower without the tractor running? If your not sure if you have done it right, do not install the pto shaft if you need to transport the rotary mower, Xtreme as it is...

Yep, that's how you transport an implement....PTO off, implement raised.
BTW, you don't need to raise the 3PH to full height...just high enough to get the implement completely off the ground so it's not going to hit the ground if you're on a rough field.
Also, some implements are heavy and long (rotary cutters are a good example). Make your turns smooth and gradual (NOT abrupt or sharp). That weight on your 3PH can toss you around or even roll your tractor.

So he raises the implement with the pto off, with too long of a shaft and it cracks the pto housing or the gearbox housing???? and this is the correct way???

I didn't post just to be typing. Raising the implement with too long a shaft can and will do serious and expensive damage to his tractor.If he isn't sure about the length of his pto shaft, he needs to figure it out before he attaches the pto shaft to the tractor. If he needs to move it, fine, just don't attach the pto shaft to the tractor.

You didn't read his post thoroughly...you missed this very salient phrase:
"once the shafts are cut to length?" Last paragraph of post #18.

I assume you meant if the PTO is not running. And that is correct. NO harm will be done provided the PTO shafts are cut to the proper length. What we are saying is DONT raise if you have NOT made sure the PTO shaft is the right length. IF it is too long, PTO on or not, will damage things. So dont hook it up and raise the implement "just to check". Verify it is the right lengh by other means. Once you are sure it wont bottom out, you can raise it whenever you want.

OK, might as well beat this to death.

In order to hook up the PTO shaft to the tractor it has to be short enough if you hook it up so the PTO shaft is parallel to male PTO connection on the tractor. That is the shortest length the shaft will ever get. Roy pointed this out several posts back.

The locking mechanism slides forward about an inch so you have an inch of slack automatically. More is recommended, of course. But it will work.

The only way to screw up is to attach the PTO shaft THEN attach the 3PH.

OR attach the PTO shaft at an angle so when the PTO shaft/implement is moved to line up parallel with the male PTO connection on the tractor it uses up the slack.

Horse is dead - beat away.

THIS is the issue.

When the implement is on the ground, the PTO shaft is on a pretty steep angle on some implements. IF it is too long, but you still hook it up, when you go to raise the implement, the PTO shaft compresses together. IF it bottoms out, something usually breaks.

Yeah, guess I did mean tractor's PTO, not the tractor itself. And BTW, LD1, your above explanation is clear and concise- it makes perfect sense stated that way. That is all I was looking for to begin with.
I can see if someone raised the mower up when the shaft(s) were not verified as being the correct length that the outer shaft could reach the end of the base of the bell on the inner shield and by being too long place pressure on the PTO shaft, housing, or the mower's shaft/gearbox and cause damage. Correct?

And this thread is not just for me it is for all newbies like me who might possibly misunderstand the written directions of the implement manufacturer and cause damage to their tractor or implement or both. So it's not a dead horse 'till I say it's a dead horse!

And for those of you who are carrying some sort of grudge match to the death over who has the biggest bell housing or whatever; take a chill pill and relax. This is an internet forum for the benefit of the members not a court of law where you're fighting for some cause or other. Life's too short- let's not give each other the proverbial 'shaft', short or long.:thumbsup:
