125 Hydro Fan Opinion Metal vs Plastic
 

I am replacing the driveshaft and related components on my 125. I did not have a hydro fan or shroud on my unit. I am putting the fan and shroud back on. I bought a new plastic fan. Now I found a nice used metal fan. Both claim to be for the 125. The parts diagram is not specific. Which should I put on and why? I am just going to use it for grass cutting and snow plowing. Hopefully light plowing and tilling in the future (small home garden). Thanks for all of the help!

I'd go with the metal one since the plastic fans always break the blades off after they become old and brittle.

I like the metal fan,

A PO removed the metal fan and shroud from my 147 and replaced it with a plastic one. The fan has since lost at least one blade, and I've since bought another driveshaft with a metal fan AND a shroud. I plan on installing it once the plastic fan looses another blade, or I get bored and want a project.

Ok sounds like the metal one is the way to go. Thanks for the great opinions!

I'd go for the metal one also.

Well, being in the HVAC/R business, I have experienced this. Both type has their advantages and dis-advantages.

The metal type of blades are more durable. BUT...if they get bent and become out of balance....they are virtual impossible to balance back up again (toast).

The plastic type of blades are less durable....BUT hardly ever go out of balance and have a lot more tolerance to a slight "bumping".

You can decide which better suits your needs.

:ThumbsUp:

I have both metal, and plastic fans what R Bedell said is correct. I have a metal fan on a JD 317 it was loose or the metal fan shroud was not set correct when turning or in any strain it made a hydro pump/rear end noise. It took me awhile to figure this out not to mention a lot of work trying to fix what was not wrong.

To add to what has already been said the plastic fans are not as durable as the metal, however the are much more forgiving to anything they come into contact with, and any damage from old age, worn loose fitting will be done to the plastic verses drive shaft/ drive line. As mentioned in the other thread securing the plastic fan in a more robust manner will eliminate the majority of the problems with the plastic fan.

Remember if using a metal fan that if it ever comes into contact with anything it will most likely be damaged if it's a hand for some reason it's like a meat grinder.
