It's not a big block...

[COPO]

Have a Kubota ZD-1211 with 72" deck. It's a beast of a commercial mower with diesel engine and can take anything you throw at it. Does a very nice job, but unless you have at least 20 acres to mow it's overkill.

Really love the mower and for whatever reason, I've always enjoyed the decompressing time that grass cutting provides and sense of satisfaction from a perfectly mowed yard.
