Hi,

I recently purchased a craftsman yts 4000 (Canandian model) and after taking a closer look i noticed that it has what looks like a fan on top of the tranny. I have noticed that even after just a couple of hours of use there appears to be some grass clippings accumulating in the top part of the fan.

How critical is it to keep that area clean of grass debris? I don't have a high pressure washer or air gun to get at it easily.

The fan has a centre depression that collects grass but that little bit of grass doesn't impede air flow. If the entire area is allowed to build up incuding the cooling fins on the hydro, then that can be detrimental.

I don't advise using a pressure washer at all on that area. Some people use a leaf blower to clear dry grass away from the top of the deck and hydro. Not having a leaf blower, I use a broom, my hand, and sometimes compressed air.

I use a leaf blower everytime after I mow or do leaf pick-up patrol. You won't believe how much debris gets dislodged from the underside of the tractor.

If the cooling fan or tranny housing gets clogged with debris, it can overheat the tranny oil and cause severe damage. Don't use water (especially high pressure water) as this can find its way into your tranny through breather holes and cause damage as well.

I have a gas backpack blower that I use. After I finish using it to blow the fresh grass clippings off the driveway I blow off the deck on our tractor, as well as the area where the tranny is on our X500. Does a nice job.

I was advised to keep the cooling fans clean and free of debri by one of my neighbors who works for sear repairing tractors. I will say I use it pretty heavily and have never found any debris on the fan. I check it every use.
