I have a post hole auger on my tractor, when it jams I lift the auger up and it frees itself. An attachment that turns at high speed and then jams with a foreign object may not have a hyd motor that can have reverse flow and start out with enough torque from a standstill to unjam itself. The...

My experience is the PT's hyd run hot and every fitting or valve would add some restriction and more heat. What implements would need to be reversed? It wouldn't be too difficult if you need it, just another sizeable valve and electrics. I have a similar 12 volt valve on a stump grinder as you...

I think they may change with the serial number groups.

Guessing 7 GPM. Most people don't want to have the crane move quickly, it should work well.

How many hours on it? Might be better to just get a new engine if everything is worn to that point.

On the PT "mini-hoe", I call excavator (because mine is not mini nor a backhoe) you dig with it by putting the bucket down where you want the hole, adjust the cutting angle and then back up the tractor to cut into the earth. The curl function (uncurl/dump) does not have enough power to pull the...

Yes, I was up half the night thinking about this. We should probably start a new thread on the need for and adding a circuit relief. I think they are mostly needed in 2 circuits, the bucket curl (aux circuit) and the attachment curl back (Z bar piston). The aux circuit bucket curl is needed...

I don't get that. When you use a loader bucket and drive into a material pile or virgin earth, then curl the bucket back to lift and fill the bucket as your driving in, I stall out the hydraulics (relief valve opens). To me that puts as much stress on everything. When Leverage comes into the...

I searched and couldn't find any info, any chance you saved the post on operators that damaged their arms while using a front excavator (backhoe) attachment? I use Titan brand hoes on my tractors which is larger and more elaborate then the PT model and haven't noticed any damage yet. I use...

That is a tough decision. I was always aggravated by the errors in the specs on the machines. For example the weight between the two (425-1387 and 422-1344) is 43 lbs different! Yet the 425 is supposed to have a 8" longer wheel base (but the overall length is only 6" difference). So the 43...

Inspect the linkage going from the handle to the valve spools. If it is worn it may not be pushing the spool in to the float position fully and maybe jamming up when going into the raise position. Also look for rust, loose parts, foreign material, etc.

That is a nice video. PT should recommend it.

The whole thing could have been caused by the starter staying "on" or if it stuck engaged. Check it out good before you burn up a new starter. Did the ignition switch stick in start position? Is there a relay that got stuck in start? Or just the starter itself? If the starter remained...

In my opinion, you don't need it, it is paid for, so sell it as is and cut your looses. Parts have gotten very expensive. If you try to fix, you may be into it for thousands and a lot of labor. Will you recoup the cost? Who knows? If you are looking for a project, dive in and have fun. If...

I don't think you can buy an air (or oil) cooled diesel anymore. So to install a late model diesel in a PT, you need to reengineer for a radiator liquid cooling system. So making if longer or higher, either way will cause its own problems. RPMs don't matter on a new product, they would just...
