I bought My Benye 254 tractor last march complete with Howse rotary cutter; and can't be sure how to hook up the drive shaft properly to the pto shaft on the tractor. it wont slip all the way on. How should it go on???? properly.

The PTO shaft should have either a yellow plastic collar on the tractor end or possibly a pushbutton. The collar pushes the pushbutton. If the collar is broken you can take it off and use the pushbutton without the collar. I took the collar off my old shaft and it was easier to hook up without it.

You can look into the end of the yoke and see the movement when you turn the collar. There should be a metal stud that is designed to lock into the groove on the tractor PTO shaft.

Sometimes the collar can be hard to turn, you may need to spray the inside of the yoke with WD40 until the collar turns freely. You will see the shaft that goes into the yoke move.

Inspect the PTO shaft and yoke for any damage or rust. If either is rusted you will need to clean them up. It is a pretty tight fit on the PTO shaft and rust or dirt may be holding you off.

Put some grease on the PTO before you try to hook it up.

On my old Kubota there wasn't much room to manuver and it was not easy to get it hooked up until I got the hang of it.

After it seems to lock on the PTO be sure to pull back on it pretty hard to be sure it is locked.

The guy that delivered my bush hog suggested I cut off the big sleeve (about 4" diameter X 4" long) that covered the collar. I just couldn't get enough grip to get it hooked up with that big collar on. He couldn't cut it off since he worked for the dealer and I am NOT telling you to cut it off.

First, look at the PTO on the tractor. It should have a groove around it's circumference about 2/3rds in from the end of the shaft.

Second..make sure the tractor key is in your pocket!. We don't want any accidents, do we?

Then, look at the implement PTO shaft (U-Joint end that goes on the tractor). There will be a pin (look for a spring perpendicular to the inside splines on the U-Joint, or there will be a rotatable ring close to the the end of the U-Joint nearest the PTO shaft.

Once you've found the locking mechanism, you're half way there.

On the tractor end of the PTO shaft, you must push the pin down or rotate the ring to release tension on the detents (same principle as the ball detents on a rachet wrench). Once you release the tension, the female splines on the U-Joint should go on the tractor PTO shaft fairly easy.

Make sure you hold the release mechanism (pin or ring) until the splines are fully engaged. Once you've got the PTO shaft completely on the (tractor) PTO shaft, give it a good yank back to ensure the detent is locked in the groove on the tractor's PTO.

If the tractor's PTO shaft and implement shaft's splines are not lined up, you should be able to rotate the tractor shaft to align them.

If it doesn't slip together, look for burrs on the splines.

Now, I'm assuming the tractor and cutter were rigged up at one time and that Benya has a standard PTO shaft size and spline. If it's a grey market tractor, it may not have a standard (1.375") shaft size or spline configuration.

Don't know about the Benye tractor, but I do have a Howse cutter. Mine has a spring loaded pin on the shaft collar. The collar will slip on the PTO shaft an inch or so before the pin stops it. Then I can press the pin in as far as it will go and the collar slips the rest of the way on the PTO shaft. I release the pin then I try to slip it back and forth to make sure the pin seated and locked the collar on properly. As previously stated, don't do this with the tractor running.

The PTO "head" that goes onto the shaft has a heavy duty version of the slip gizmo like is on air hoses. Mine is actually a button. What it does is release tension on some little balls inside (like those on the air hose) and allows the "head" to slip onto the shaft. Let up on the button, and it locks in place, as the balls drop into a groove around the PTO, back about and inch or so from the end.

I've found it very difficult to both support this "head" (and shaft), push the button and find the splines aligned correctly. So, what I do is droop a strong bungee cord across the bottom of the end of the shaft behind the "head" that holds the shaft close to the right height. You'll have to find the right places to attach it and length and strength of bungee cord to do this, but it works for me. You sometimes have to rotate either the shaft or the PTO to get the splines aligned. The shaft riding on the bungee will rotate fairly easily.

I have encountered the same problem. The end of the drive shaft that attaches to the pto on the tractor has a large black ring. There is no type of spring loaded locking mechanism. On one of the splines on the driveshaft, there is a raised "bump" that only allows the shaft to go onto the pto shaft approximately 1/2 inch. I can't figure this out. This is a brand new howse brand 4' bush hog. Dealer didn't leave manual when he dropped it off. Any ideas or this correct that the drive shaft only goes on the pto shaft 1/2 inch?

Guess I noticed this thread a little late, but I went through the same thing with my Howse rotary cutter.

I described my problem and pseudo-solution (with pictures) here. /forums/images/graemlins/crazy.gif

Jutt, welcome to TBN. I suspect the type of shaft you have requires that you turn the large black ring one way or the other to open up the locking mechanism, slide it on the PTO shaft and let go of the ring which should spring back. Then pull back on the shaft to make sure it's locked into position. Make sure you line up the PTO to the shaft collar before you try to slide it on. You can turn it with your hand while holding the shaft up close so you can feel when it hits the shaft guides, then so as above. John

Kioti John,

Thanks for the reply. The black collar on the shaft won't turn either way, left or right or back and forth. When I line up the splines, it will go on about a 1/2 inch onto the pto shaft before a raised "bump" in one of the groove's of the drive shaft stops it from going on any further. This "bump" will not move in and out due to it being part of the shaft itself. I'm going to take the shaft back to the dealer today and see if he can help and give me a manual. The tractor is a Kioti LB1914 that I bought used with 65 hours on it with a Kioti 60" finish mower and the howse 42" brush hog.

Those driveshafts are pretty much all aftermarket and not a part of the implement or the tractor, so I doubt that it will be in a manual. If your ring won't move in any direction, sounds like it is jammed.
