Videos of New PT425 Arriving/Unloading

[MossRoad]

Folks, after a couple of hours blowing snow yesterday I decided to unattached the thrower and attach the sweeper. The 1/4 quick connectors came off easily. But I could not re-connect the QA coupler -- it just would not connect. My neighbor dropped by and he could not connect it either. We tried all the techniques discussed in the thread to no avail. To be brief, the next day we were finally able to connect it only by one person holding down the Aux handle while the other pushed the connector on. That is a new technique that I could never do by myself. Frustrating! I did try the tap tap method to relieve the pressure in the hoses. Cycling the Aux level did not seem to work.

Below are some photos of the couplers.

Before I knew about the punch and tap method, I had the same problem once trying to reconnect the QA. I took an open end wrench and cracked the fitting at the QA cylinder until a couple drops of oil came out. Then it was easy to reconnect it. I posted my problem here on TBN and that's when someone, Bird, I believe, told me about the punch, rag and rap with a hammer. That method I've used maybe twice and it worked well both times.

On the snow blower. Skids might be a good solution to your deal. If they are bowed in the front and back (tips pointed up) sounds to me it would be a good solution to your digging in.

I am wondering if a small pressure relief valve could be installed on the QA hoses????

The suggestion is interesting. A simple approach would be to weld the skids on leaving a 1.5" to 2" clearance. Having the skids be adjustable would be more complicated without much enhancement to the result.

Wow it's really too bad that you are having so many problems with the QA couplers. If it is really bad, just take the coupler off, only takes two wrenches and a couple of minutes. I know mine were pretty stiff, and they seemed to get much better after they got broken in. It honestly sounds like PT got a bad batch of QD couplers, and I would call them up and make them replace the couplers under warranty. How can they argue this problem? If it is not the connector, then the hose, or the valve block. Just keep going until it gets fixed. One word, "unacceptable."

I feel for you Clumber.

The problem of having trouble connecting QD's is caused primarily by the pressure build up on a hyd attachment due to expansion. The connectors need to be tight so there is no leaking when disconnected. If you connect the attachment QD's together, the problem is reduced. That only works if you have a male and female QD. You could also connect a matching QD with a short hose, and plug into the attachment QD's. The air space in the hose will absorb any hyd pressure.

How is expansion occurring when the PT is not running, and out in the snow?

I have seen this happen when the unit is exposed to the sun. Was it sunny that day? Try the pin and hammer technique.

Yes. the temp was about 30 degrees. However, the Quick Adapter's hoses, while not being connected, dangle in close proximity to the working hoses which probably get very hot after blowing snow for over two hours.

Anyway, I am thinking of making an adapter made from two male connectors threaded together via a male/male threaded bushing. In other words, two male connectors facing away from each other with a m/m bushing threaded to the female port of the male connectors. Would need one for each attachment with the two female 1/4" connectors plus one for the QA plate. Then the two female connectors could connected to prevent pressure when not in use. This would be easier than building or buying custom short hoses. But, would the air space in the bushing be sufficient to reduce the hyd pressure?

IT was overcast and approx 30 degrees F. I tried the punch, rag, and tap several times. There was oil released.

The other thing is to push the aux PTO handle up and down for a couple of seconds each way. I do this prior to every connect/disconnect time. That releases pressure at the PTO. Did you use the pin on the quick attach cylinder?
