Well I finally got tired of using a WB on small residential lawns and went out and got a 2007 mini z JD717a 48" with 19 Kawasaki. Looked at ex-mark, scag and JD but liked the warranty and service that JD dealer has to offer. Plus picked up for $5,995.00. So far last week it saw use at every lawn and so far it is much faster than 2 WB being used on smaller lawns. should have purchased a mini z from the start instead of WB.
