Well I finally found a cooling fan for my ff18.the factory fan was gone.it took me the afternoon but got it done .the replacement was from a ford but worked well with a few tweaks.the set screw on the the key way went back as removed but the other set screw was replaced with a 3/4 inch bolt with a rubber spacer between the fan and the shaft.it snugged it down nice and tight.works like a champ.

I've often wondered if those fans are really all that neccessary?  Seems they are built so cheap, have seen many with blades half or all the way broken off and been for long time, and no running issues all that time. I kinda think they were an afterthought and just some sort of insurance for tractor to last the warranty time, etc.  What's others thoughts on this??

i thought about that too but i figured that it must be there for a reason.dont know how long this one was missing but i plan on working it all summer if it ever comes. don't want to cook a hydro on these because parts are hard to come by and $$$$$.

Tom, glad you got one on there! Tom, does the FF18 have a cooler on it like the FF20-24's do?

Grumpy, I've often wondered how much good they do, but you are supposed to run a hydro at half throttle or more. So that fan is spinning at 2000+ RPM's. Has to move some air around the charge pump and hydro, thus cooling it some.

 

 

 

EDIT: Just pulled up the manual and it does have the cooler (or supposed to).

Yes, the fans are necessary.  Pressure makes heat, and heat causes seals to burn up.  Or, worst yet, the high heat will break down the oil and causes it to cavitate the metal internally. 

 

I've seen many zero turns run without their hydro fans... until one of those two things happens.

I had a newer Simplicity (hydro) riding mower. I didn't know it but the fins on the fan broke off, and you guessed it, it quit moving back & forth!

yes it does have the cooler up front but the more the merrier in my opinion.

i think the cooler up front cools the fluid itself but the fan cools the hydro unit in the rear in my opinion.
