IMO your productivity will increase not only from the mower change but, the lack of fatigue. I recently demoed a standon mower. I didn't break any speed records getting done. It might have saved me about 5 to 10 min. on the lawns that I used it,BUT, I felt a lot less tired when I got home. I think it is worth paying the extra money. I would look at the standers. They are close to the production of the riders, but a 1000 less in price. I demoed in Florida too. I would rather have my knees take the shock than my back, plus it is more comfortable then a WB becaus you are leaning against a pad, not balancing all day on a velke or slide.
