Hello, I am new to this forum. This spring I purchased a used Toro 724-Z Proline mower with a 60" deck. It has a 24HP Onan engine. I bought this machine to use as a backup. It has around 450 hours and it appears that the owner I purchased this from took good care of it. Has any one of you used these machines in the past? Any major problems?. I really like it. It handles well and goes fast. Also has a good cut. Any suggestions on the use of blades for this mower? Did Dixie Chopper build this for Toro? I would like to hear your comments or suggestions. Thanks!
