Just bought my first tractor, a CK30 manual, with an auger by another manufacturer who recommends instantly turning the tractor key off when the auger snags. Is this the best for the tractor? Wouldn't it be better just to depress the clutch?
Thanks,

Sounds like boiler-plate lawyer speak.
If the auger snags I would think it would snap the shear bolts long before you could get to the key.

Yes, shear bolt will go before anything can be done, but they say that continued rotation can cause the bolt to weld itself to the side.
To shut kioti down the manual wants you to disengage clutch, put everything in neutral, lower rpm, then turn the key off.
It seems better for the tractor to first hit the clutch before doing anything else, instead of just suddenly turning the key off. That is my question though. ....

I suspect that Kioti's instructions are given more so that when you start the machine next time it's not at full throttle, in gear and with the PTO engaged.
I've laid waste to more than my fair share of shear-bolts in my day. The worst part is that the head gets peened over to the 'downstream' side of the rotation and can be a PITA to get out.
I can't imagine how long you would have to let it spin before it even got hot, let alone hot enough to weld itself together.
Best of luck. ....

I read with interest these replies and remember once helping my hephew with a very well snagged auger. Nothing sheared and nothing stopped until the full auger was in the ground held by tree roots. So, shear bolts as is any safety device is not 100%. That was when I wondered, where is reverse? It was a lessoned well learned in keep ready to stop the PTO at all times. ....

I learned the hard way too, reverse was a crow bar and a chain. To avoid that happening to such a degree, lower the 3 point inch by inch so the hydraulics are always about to support the digger rather than allowing it to screw itself all the way into the ground freely when you drop the 3 point lever to the bottom. Then it is more likely to be just a turn or so before you can lift it free. ....

I understand the crow bar, but the chain? From my limited experience I learned gear ratios are in your favor if clearance allows you to use crow bar or such in the PTO shaft and not the auger shaft. ....

"...so the hydraulics are always about to support the digger..."
This could be a very dangerous thing if the auger caught something thin but solid, or hooked into some soft clay.
I have seen it happen all too often.
Before even a very experienced operator could get to the clutch the front wheels were well up in the air. Not disengaging the drive would have tipped the tractor to a VERY dangerous angle, if not over sideways.
It is far safer to allow the auger to corkscrew down into the dirt.
Best of luck. ....

please help me understand the turning over sideways. Was that with a 3 point mount or a side mount? Was it on sloped ground or level ground. I have seen this happen with 3 pt and it did pick front of tractor up while the auger went all the way and I mean all the way down before the clutch could be hit. One point I have not seen mentioned and could be missed it is be sure to run LOW rpms. THis is not a case of the 540 range if you are not sure of clean dirt. ....

kthompson, you bring up a very good point.
PHD's should always be run at a very low RPM, just enough to do the job. This will also reduce the wear on the auger tip.
Unfortunately you don't always have the option of operating a CUT on flat, level ground. If you tipped the tractor way up when it was on even a relatively gentle slope it would be easy to get the Center of Gravity high enough to allow it to flip over since the engine (and possibly FEL) would add a LOT of weight to the front end. You want the weight down as low as possible, not stuck up in the air. Also, the tractor is far narrower than it is long, that usually means it goes over on an angle and onto it's side.
Best of luck. ....

I guess common sense is not. Having the 3 point about to support the digger and actually digging a hole at the same time would require your hand to be on the position control lever and slowly lowering it, and therefor if it did start to lift, you would not need to disengage the clutch, just pust the lever down allowing it to corkscrew into misery. So to all readers, do not just reach over and tap the position control a little and then move your hand far far away, leave it there. ....
