Belt for 48" deck

I wonder what the mechanism for the 180 PTO clutch is. Does it have wear during engagement. Perhaps it's like an automotive clutch. Is so you might protect it by slowing the engine down during engagement. Remembering would be the hard thing.

Bob, I believe that the 180 uses a valve similar to the one below. This is what my 1445 used to control the speed of the hydraulic motor. You can engage it at full engine speed. In the off mode, it is just bypassing fluid back to tank.

OK, I see now. Thanks.

Well, what can I say...another problem.

I was doing the grass, and because of getting the 422 back awhile ago from service (they didn't hook up the hot wire for the fan), and noticed the fan was not working, I now have a tendency to look at the fan every now and then to see if it is turning.

It was not turning!

I checked the connections at the thermal relay, tested for power and ground. Checked the fuse. All ok.

Went back to the fan, cut the two wires going into the fan assembly, they have power.

So...I guess the fan is shot!

Has anyone replaced one of these?
Where did you get it?
Do you have to go through Power-Trac?
Is there a local place I could get one?
How much did you pay?

Thanks,
Abe.

My fan is still the original with 640 hours on the meter. Someone mentioned this fan and I bookmarked the site.

When mine failed on my 425 at 210 hrs I went to autozone and purchased a universal 12" replacement unit. It has worked fine I now have 400 hrs. the fan still works but I am in the process of replacing the roll over assembly and I have a wheel motor leaking for the second time. Always something.. Maybe we should start a thread to list problems with everyones machine with the hours to failure. If something comes up as a common failure at least you could monitor your machine.

Clarke,
Do you have a pic of the one you bought from autozone?
Also, did everything fit correctly?

Idabe,

Found this part # for the fan could not find Mfg. (P/N 733680). The fan does not fit out of the box. I had to elongate the four plastic mounting feet with a twist drill, very minor adjustment. Fits perfectly when modified. It also has a reversible blade and motor if you would like to run it backwards. A word of caution when drilling the plastic feet. Put the plastic foot in a vise or hold with a vise grip or you will break the plastic foot.

Clarke,
I bought the fan (P/N 733680) from Autozone today, and it is almost a perfect fit, just like you said.

I turned the key on and touched the PT fan wires to the new fan connection to see which way the blade was going to turn......
..........and nothing happened! (argh!)

Did I get a "bad" new fan?

Nope, I took it over to my car, hooked up the jumper cables, and touched the new fan wires to the cables...and it turned right on! (Though from the factory the new fan blows down onto the oil cooler instead of drawing air out like the original fan, but I think that can be rectified.)

So now I am thinking, maybe the old fan wasn't bad. I take it over to the jumper cables and IT STARTS TURNING RIGHT AWAY!
