I'm here in Texas & have my new card for my Ag exemption. I went to buy a zero turn lawn mower. The salesman shows me the price & included is over 500 dollars in taxes. I said wait a minute I'm buying this mower to mow around my trees in my pecan orchard. He says nope you gotta pay the taxes because its a lawn mower. I have the money to pay the taxes but why should I. I sell the pecans when they produce & I can find someone to pick them. I live on a hundred acre hay farm been selling hay for over 15 years. What should I do?
