I installed a 1500 cfm cooling fan on the back of my mower, now I can mow most of my yard, which take several hours , before I had to stop and let it cool in about 15 minutes. I drilled 1 inch holes in about a 7 inch circle and installed the fan to blow onto the trans. It has helped alot. I paid 32.00 for the fan from dmmotor in calif. toggle switch on the dash with an inline fuse to the battery. I have a LA 150
