I will let russ,  173abn, comment on Grasshoppers ..  He has a diesel powered one...:thumbsup:
If you have more than an average lot to mow you will appreciate a good quality mower. A commercial mower is GREAT quality... They are built to be serviceable and you can expect thousands of hours from them....
 also there is nothing like diesel power for mowing:smile:  :smile:KennyV
