Help Fastrak 20/52 Hydro Fan Blade

[mbaug]

I was mowing today on my 2004 20/52 Fastrak and my drive belt came off and tore the plastic fan blade off the Left Hydro. Not sure why it came off but all the idler pulleys are rotating OK. I have never replaced this belt so when i replace the fan blade I am going to put a new belt on.
2 Questions
What is the Part number of plastic fan blade on top of the left hydro pully?
I just mow my property (3 acres) so can I mow without the fan blade on until I get the new one or will the left hydro overheat without the fan blade? I have changed the hydro oil and filters several times.

I would not mow without the fan on the pulley.
The fan is Hustler part # 785725

Thanks for the part number. I went to my dealer last week and they gave me fan blade # 799486. This fan blade has a bigger bolt pattern and the fan blades are curved the opposite way. How can I get a parts manual for my hydro pump? Fastrack 20/52 Serial Number 926501 Serial Number 04080112

The fan blade you have is for the TrimStar walk behinds.
E-mail me and I can email you a service manual for your hydro unit.
