Keeping things cool

 I mowed the front yard in 94 degree heat, checked the motor temperature directly after and got 170 degrees on motor and nearby batteries were 140.

I had ordered a 48 volt computer fan on eBay and decided it should be tried out for cooling. 

The fan moved a crazy amount of air, sounds like a jet engine, at one point sucking my t-shirt in and shredding it.

Not wanting to lose any digits, a guard was needed. I dug around and found an old speaker grill that fit, right down to holes lining up with fan mounts. 

I modified the grill for better air flow by removing fabric and cutting some slots.

I made a bracket for the fan and mounted it over the motor, since there was a hole in the metal I used , I installed a disable switch. 

I wired it through a fuse to come on when the drive motor runs, I will check temperature next time I mow, but I’m confident they will be less, just a matter of how much.
