4650 cooling fan clutch

want to know if there are any aftermarket manufacturers for viscous fan drives? John Deere dealer wants 600 dollars. Just wondering if there is any cheaper out there

I bought a kit from JD and just locked the fan on my 4255 solid so it would run cooler down here in the summertime in Tx.

My fan is already been locked up with the same kit. I was wanting to change it with a new one. They claim locked up fans rob 10-20 hp from tractor depending on the size and reduce the fuel economy of tractor. With the high fuel prices today you need all you can get. Thanks for the reply
