While having used the 21's quite successfully with a 2 man crew this and last year, I decided to bump it up a notch with the Quick 36 Super Duty. The last number we averaged on our 3 best days per 2 man crew for this particular route was 3.46 lawns per hour. Rather than add a 3rd employee to use the additional 21, financially the Super Duty came out to the more logical decision. It only arrived today, therefore I do not have any comparing numbers. After using it on my own lawn, I'm extremely excited about this change. So far my observation is that it cuts better than a Toro 21 Proline in St. Augustine, and is faster as well. I may have some Bermuda photos over the weekend. As far as hauling it, as you can see in the pics my it's business as usual on this truck. Thanks to Gary and PTP who both suggested I should have no problem fitting this into a ranger. I should have bought one early last year.
