5205 hydraulic fluid leak?

[HillbillyFarmer]

At 10 hrs, I noticed the fluid was low in my new 5205 and called my dealer. He sent me 2.5 gals (free). It took about a gallon. This AM when I checked at 13.5 hrs., it was low again and took the same amount.
I checked all over and can not find a leak anywhere.
Any ideas?

Hydraluics may not have been purged of all air at first. Using the tractor allows them to fill up. I had to add about a gallon when I first had my 4300.
