A few considerations.
JRCO makes two row tine dethatchers, largest is 60" wide. They make adapters to fit onto most major makes of ZTRs.
Is the property absolutely flat? The wider the deck, the more it will dig into irregular turf.
Does the property accumulate a lot of leaves in the fall? Leaves can be mulched, but the pieces don't decay very quickly.
I recommend a deck width in the 60" range as a 72" deck with a collection system is a very wide machine to store.
Does the property have an area where grass clippings and chopped up leaves can be easily dumped?
Who will perform the maintenance on this machine, staff or dealer?
Being in rocky, rooty, hilly New England, 52"-60" decks are common. I have a Scag Tiger Cub/48" deck/collection system/ 46" JRCO tine rake dethatcher.
I also have a Hustler X-ONE/60"rear discharge deck that is used primarily in a cemetery.
Both machines are quality and I recommend looking into their machines.
The JRCO tine rake dethatcher is an excellent attachment that can be raised and lowered easily during machine operation.
