Welcome aboard! These garden tractors just rock, and are built very good. The time and effort you take to "restore", or simply bring back from the dead is very rewarding. I have been around for awhile, and the folks you meet, deal with, and associate with is a pretty fun adventure in itself! Many of them have helped me with this model 72 I repainted and rebuilt.
By the way, their no fun to stand back and look at! This one keeps the drive cleared of snow during the season. Unlike your zero turn, these garden tractors are very versatile!
Well, good luck !
