Looking to add a 36" walk behind to my arsenal this year with bagger and possibly a sulky. I am interested in acquiring one to get into the back yards with gates and other tight areas that my Z wont be able to slip through. Not really interested in pushing the 21" and eat up loads more time at a property. What are the diff's b/t hydro static (are they always dual hydro?) and belt drive? (besides price). Is durability and quality of cut the same? Again, looking for a good priced 36" walk behind with bagger, sulky, and leaves a nice clean cut. Budget will vary depending on if i get a used or new ofc. Please lemme know what you guys would go with and why!
