Whats going on with the PT429

[woodlandfarms]

I read you note about the 4 in 1. I have a grapple on my materials bucket (3rd party so very heavy duty) but I really wish I had just a bucket and a seperate grapple with bottom rake tines instead of the flat bottom of the bucket.

Oh, well.. . Could not convince the CFO that another 3K was well spent.

The 1430 has a 12 GPM PTO versus 8 GPM for the 425. Both are 2500 PSI. I don't know if the QDs are the same or not.

I think you would have to rig a bypass for the PTO driven attachments so that some fluid flows around the attachments and back to the tank.. I believe this has been discussed somewhere here before. PT has a technique for this.

I think the first thing someone contemplating using a PTO driven 425 implement on a 1430 should do is read. As in read the specs of the implement's motor. Of course the usual sleuthing may be required to find out what Power Trac hath wrought in the way of hydraulic motor for the attachment in question. It may be that the motor can handle the flow of the 1430 without issues. If it can't, then further adjustments may be required.

Snow, that't a good point, but even if the motor can stand it other components might be stressed beyond what they can stand with reasonable life.
However, all components (buckets, forks, minihoe) will be stressed more by the larger machine. This has been my major concern. The hydraulics can be bypassed and I guess for lift you could change the relief valve, but the motive force would be greater. You could also just fix or upgrade whatever fails but this is not ideal.

Is there a relief valve on the PTO? I have never really looked, but if I turn my PTO on without an implement hooked up, my engine stalls.

If there is a relief valve, it is way out of adjustment. I have always assumed there was no relief on the PTO.

How in the world did you manage to bend them, Moss? The forks and the light materials bucket are about the only things PT-425 related that haven't bent or broken on me.

One time I jammed them into the ground and kept wiggling the joystick left and right to vibrate them in as deep as I could to get under a concrete swing set anchor and pry it out of the ground. I got it out, but the left fork bent down about 2".

Another time I was lifting a large old 3PT brush hog from my IH and I got one fork under the blades and the other over the blades. When I lifted the thing, the forks got pinched and as I tried to maneuver it, I accidentally applied down force to the joystick. Bent one of the forks up, I believe.

Then there have been the numerous tree stumps/roots getting pried out.

It think it really shows the power that the hydraulics have on these things when a 1500 pound tractor can bend thick steel like that by wedging them against something and applying the pressure.

There are various relief valves on the PT. Stalling the engine is good in that mode as you do not want to open a relief valve for long. I most notice it when I pick up something to heavy with the forks.

I found the PTO relief. It is screwed into the RPS assembly, but I don't think any reliefs would have to be changed. Both machines are spec'd at 2500 PSI.

I have never had the lift/tilt relief open to my knowledge. If I try to pick up something that is too heavy, the rear end comes up, and I'm not about to push things any further.

If I put weights on the back (which I normally do), then I can trip the relief valve.
