Here's the deal I have a Toro ZM 48" and a 36" Stander. My problem is the yards I use my stander on(backyards) I am having an issue with "nipples" when making turns b/c there is not a lot of room to change cutting directions and it seems my only option is to go the WB route. I have 2 questions regarding this: 1. My Stander doesn't even have 100 hours and is completely paid off, should I keep it or sell? 2. What WB should I go with? I want a 32" to be able to get to all backyards and I want something tough and easily adjustable as my Stander is the fixed deck. I also need a 21" what are your opinions on what I should get. I want commercial grade. Thanks for your guys' help.
