I am looking at the King Kutter 72" Landscape Rake w/ Wheels 4500-LSR-72-GW listed on RuralKing.com for $869.99. Has anyone used this rake? I have contacted KK since it is not on their Web site, so I want to know if parts are available, etc. It is not clear to me also if the tines are the same as on the KK YR-G-72 Pro rake, and if the spacing is the same. If anyone has more information on this 4500 rake from KK I would appreciate it. thanks, Scott.
