Hello from Louisiana

[SwampmanLA]

Hi all. I'm new to Power Trac as I made it home with my PT422 on Friday.
I put it to work on Saturday moveing about 30 yards of topsoil. I was really impressed with the power of the 422. Here is what I bought:
PT 422
48 finish mower
Mini-hoe and thumb
10 cu ft bucket
48 box blade
Pallet forks
Towing adaptor
Spare Tire

Now I wish I had more good things to say but today I fired it back up and the tram pump seems to be on the blink. When trying to tram I have no power and hear a knocking sound from the wheels. If I get it rolling real slowly I can then tram at full speed but with no real power. Not what I was hoping for with only 9.5 hours on my new toy. Oh well I guess Terry gets a call in the morning.

Hi Swampman,

Welcome to TBN. and the PT forum. We didn't know you were looking. Anyway, glad you got what you wanted, but sad to hear of your trouble. PT may try to pass the buck, so jump in there with both feet and stay on them until they make it right.

I just thought of something else. Check the bypass valve and see if it is completely in the tram position. That clunk in the wheel motor doesn't sound good.

Thanks, once I figure out where it is I'll have a look at it.

The clunks may be the parking brake not being fully off. It tends to drift on if the nut on the handle is loose. Check the bypass valve for low power as was said by J_J. It should be under the tram pump if it is like mine.

welcome to the forum. Hope you get the problem fixed without to much trouble. A call to Terry would definately be inorder. As already mentioned you did check the parking break, sometimes if it isn't fully retracted it will make a clicking sound. But by you not having power to the wheels that don't sound good.

I thought of the parking break right away and checked it out, that is not the problem. Then I thought of air in the system and did the bleeding proceedure, that is not it. Then I pulled a tire and checked the key on the spendle and hub, again that's not the problem. So I'm left with the pump or bypass is shot. will let you know.

Are you running it at full throttle or really low throttle? I ask, because if it is at low throttle, it will make bizarre noises, especially if you depress the treadle pedal all the way.

Check for leaks inside the tub. Also check to make sure the hydraulic oil filter is tight. If that gets loosened (and they do) you will get that no power although it doesn't explain the clunk.

I talked to Terry this morning and after some head scratching he decided that it is likely a plugged hydraluic oil filter. How could that happen with new equipment (9.5 hours total time). He says that of the three pumps, the tram pump is the only one that uses filtered oil. That is because the tram pump is a piston pump and the other two are gear pumps. The gear pumps can take some trash but the piston has to be squeeky clean.

I don't know if I buy it but I'll give them a chance. If that does not work a new tram pump better be on the way pronto. BTW, he says it's a snap to change out. I hope so!
