Post Hole digger stupid question

Newbie here with a TO30.

Borrowed a PHD from a neighbor, used on his Kubota.

TO30 has an overide clutch adapter to 1 3/8, neighbors PHD PTO shaft connects just fine, sort of.

When I use the finger tip control to lower the auger, the cutting edge pulls towards the tractor to almost 45 degrees. I can't get it to go straght down.

PTO shaft length to long or short?
Boom has three adjustment holes which I haven't tried yet, currently it is connected to the closest one to the tractor.

Any help would be appreciated.

Is the auger leaning as the leading cutting edge digs into the ground when starting the hole? Lower the auger to the ground so the point digs in then gently start rotating the auger. There is a point on the end of the auger? I have welded a cold chisel to the very center of an auger that had a too short point. Worked very well. As for borrowing equipment? I dodn't care if it's just borrowing a hammer. Treat the tool/equipment like you would want somebody to take care of your wife if they were borrowing her. Needless to say I don't borrow or lend stuff.

You borrowed his auger. Don't cut the shaft. Borrow his tractor, too.

What you are describing does not sound like normal operation, and you can easily bust something. At this point, do not put the auger on the ground and drive forward! I believe that _will_ bust the pto shaft. Something is binding..... (As others say, the auger will lean slightly as one digs, but not as much as you are describing.)

Because you are using the adaptor shaftpiece, I think it is obvious to assume that your shaft is now too long. (You know what happens when we assume....)

Ignoring all other parts, the pto shaft that is a part of the phd should easily telescope when not connected to the tractor. Longer & shorter. It should do so easily. If you need to tug hard or pound on it: It has not been greased in a long time, and the rust is binding it up something terrible, and it will bust without getting it apart & lubed up. Or, it got bent and will not ever slide right any more - it is ruined.

If it does slide easily & is lubed up when not connected to the tractor, then likely the addition of the size converter is making the pto shaft too long. Using it that way will wreck the pto shaft, your tractor pto stub, or some other part of the phd. Don't.

You would need to cut off both parts of the pto shaft to make it shorter; find a shorter one; or use a different adaptor as someone mentioned that does not make your tractor pto stub longer.

Can't tell which it is, but I would suspect the adaptor is making the shaft too long.

Because of the angles, as you lower the phd, the pto shaft bottoms out, and pushes up on the phd gearcase. This tips the auger towards the tractor.

Regardless if your Auger is a sophisticated Hydraulic driven one mounted on the side of the Loader Arm such as Morton and Wick use or a Farm style Pto driven Auger useing your 3 point hitch. The Arc of the down ward travel of the Lift arms or the Loader Arms will cause the Auger to gradually go to the oblique unless you correct its travel by easing your Tractor to the rear or forward as the auger descends into the Earth. This is natural and does not mean that any mechanical malfunction has occured.

Mark, I always found that as the PHD started into the ground that I would have to ease the tractor backwards or forwards until the auger was going down 90* to the ground. When you have the auger raised does it hang down at 90* to the ground? I don't think you are doing anything wrong in your hook up to your tractor, that is the nature of an auger and you may have to get used to backing up or moving ahead a little as the PHD starts down into the ground..Mike in Exeter Ontario

Thanks Mike, I did not know that.

The auger does hang straight down when raised fully, however as it starts to decend it pulls up and away before it reaches the ground.

How easy does the slip part of the PTO shaft move. It need to be well oil/greased so it will slide in and out pretty easy or that will cause problems when you low it.

Do you mean where it connects to the PTO on the tractor or the gearbox above the auger. The tractor PTO adapter is dry, the gearbox that came with the auger is old and rusty but seemed to turn ok.

Niehter place. The PTO shaft has a slip joint in the middle which lets you let or lower it. If it didn't you would brake the shaft when you either lowered it of lifted it. That slip joint needs to be able to slide in and out easy. Most slip joints are an square tube with a square bar shaft inside of it, the 2 slip in and out on each other. If they don't slide in and out easy it will pull or push on the auger and make it go forward or back as it goes up or down. Take the shaft loose from the tractor and push or pull on it to make sure it slips in and out easy. If it doesn't pull and apart and clean the inner shaft up and grease it real god and then put it back togeather

Thanks Old, this makes sense,

I have never worked with a PTO shaft extension before so...

The PTO shaft extension/connector I am working with has a plastic sleeve/housing between both universal joints, covering the possible slip joint that you mentioned. Do I just pull hard from both ends to seperate it or can I get the sleeve off? Maybe some banging with a heavy hammer?

Should be able to justtake it loose at the tractor and then pull on it. Some of the real good ones have places on them to grease them so you don't have to pull them apart. Look for a couple holes in the plastic cover and see if there a couple of zirks on the shaft. If there is then just greaes it real good the raise and lower it a few times.

Before you ease ahead w/ it in the gruond, lower it just above the ground if you can and try to rock it back and forth. If it doesn't want to go back the pto shaft may be too long for you tractor.

Thanks Don,

I would think if the shaft was to long that the cutting tip of the PHD would push away from the tractor, not be pulled towards towards the tractor?

Am I missing something?

Thanks

Think about your angels. You are not pushing "out" as much as you are pushing "up" on the PTO connection. You would be pushing up on the side of the PHD towards the tractor, point would travel towards the tractor (sesaw affect).

I agree with the others.. a 'too long' pto shaft will push the gearbox so that the cutter tip moves toward the tractor..

Perhaps the 4-6" made up by the orc is doing it... If that is so.. he can remove the orc and simply use a 1 1/8 to 1 3/8 bushing that will not effect pto shaft length..

Like 504 says, due to the angle, it'll push the gear box up, thus pushing the auger towards the tractor.

Mark, Think about the angle of the shaft, yes the shaft is too long and it is pushing the digger foward.

Make sure that your stabilizers on the tractor are tight as sometimes having a lot of play will let the auger walk.

Wow! Where's Mr.Obvious when you need him?

The addition of a PTO adapter or overrunning clutch shouldnt be a factor in the overall length (provided it's not a PTO extension!) I can't believe that the drive shaft of the digger is to long. It works on the Kabota which is a similair size tractor physically.


I think Old is on to something.
