DEF D'oh

Tractor man with a lot of years on the tiller, started off running a cable hoist tractor.... Dumped 2 jugs of Def into the hydraulic tank on a new D4k, new enough that this was the first time it was added since she came from the dealer. Ran it for about 20 min before the computer shut him down. The Cat man flushed the system 4 times. Turned the fluid a lovely shade of pink. No marking on the hydraulic fill neck, and no one came to do a walkthrough of the machine with the operator. Surprisingly enough, Cat is coming good for the bill.

Reminds me of when my wife put windshield washer fluid in her master cylinder resevoir

I wonder what DEF and Brake Fluid do together......

did he not read the manual ??
