Hey guys...new to the site and new to Lawn Care. I've been using a 21" since the start of the season...and Im about to die!!! So I'll be getting a Quick 36 Samurai by the end of the week. This may be a stupid question, but how much difference will I notice from a 21 to a Quick 36--and I have 23 accounts? Im sure it's like 2 different worlds...geez I hope!!!
