I'm new to the site but have been viewing awhile. I'm fixing to buy another Ferris 3100 with 61 inch deck. I have a 3100 61 with a 37 DFI Kawasaki and it has plenty of power its just a gas hog. Will the 32 Vanguard have plenty of power for the 61 or should i get the 36 Vanguard. I mow full speed most of the time cutting some weekly accounts and bi-weekly. All the properties i mow with the 3100 is big open mowing some of it is thicker grass most of it is fairly thin. 32 or 36?
