A tough one for someone smart in engineering

I was finally initiated by having the PT pucker with my 1850 about 6 weeks ago. Strange feeling but easily reversible. Now if it had been a regular tractor, I would have had to act extremely quickly or I would have rolled it.

Love the PT!

So Ken, tell me what happened. I cannot get the back to rise on my tractor... Even when I grab something that is cleary way too big...

Try grabbing an immovable object with your minihoe, when on a slope, with the PT pointed downhill...

I can pucker mine with the minihoe/thumb regardless of slope or how the tractor is positioned on the slope. For example, I can get it to pucker facing uphill, if I grab onto a sapling that it won't pull out of the ground... I've used mine quite a bit for "grubbing" -- pulling out the smaller undergrowth, roots and all, since the wild holly that's all over my lot suckers and sprouts like crazy if you just cut it off. Instead of cutting them off and then using brush/tree killer on the stump (which can puncture tires, etc.), I just pull them out by the roots with minihoe...

Carl, Seem to me that you mentioned that you could not lift at or around the max load, and if that is true, then you will probable never experience the PT pucker. You said your bucket would not lift beyond a certain point. So if your cylinders are not leaking externally, or bypassing internally, then the joystick valve or the pump is not operation up to specs. You can take both those items off and take to a hydraulic shop for testing. I did and found that the hydraulic lift motor was operating at 50%. It did what you said your bucket did, partially lift and quit. You need to do the PT pucker in a controlled mode so you will know what to expect, and what to do about it.

Hi Carl,

I was lifting a heavy load (it could barely lift it - and that was with using the curl to raise a few inches). It was on a slight slope, started to turn and let's do the PT pucker. The load rested on the ground with the rear wheels in the air. Just straightened out the steering and it went back down.

I think my loader valves are crapped up because I can not lift as much as I think I should now.
