Twin cylinder cast iron liner 24 pony engine driving a 48" deck, that's going to be one sweet mowing machine. Enjoy! Amsoil synthetic grease the spindles.....let her spin up and eat.
Welcome to TBN and congratz on the purchase. I really like the x500 series. I had one for a very short period of time. It was nice GT. I wanted to keep it but couldn't afford a GT and a SCUT. I think you will be very happy.
