I've read quite a number of posts that a Quick 36 can cut mowing times in half from what one can do the same yard with a 21' self propelled. Is this with bagging, mulching or side discharge? And how much time is saved with the Step Saver in wide open areas? Also does it mulch that well with the standard blades or are the Gator blades required to get a similar mulching experience as I get from my Toro Super Recycler? So I guess what I'm getting at is I feel that the Quick 36 is the next logical step to cost effective fast track to productivity thus adding more clients to be able to justify bigger equipment possibly down the road. What I'm doing now is bidding on weekly mowing clients based on 30% to 50% increased productivity of the Quick 36. I'm losing what I'd like to make hourly to secure the client mowing with the 21. Since I don't have a huge number of clients it's not an issue & I have my other business to cover most of my living expenses. So at what point in a solo operation does a Quick 36 become a slow boat compared to a bigger commercial riding mower? My current limitations are my trailer size right at 4' x 8' and the tow vehicle is my old 85 Toyota 4 cylinder 4 x 4. If I get a decent commercial riding mower I would not bother with a trailer smaller than 6 x 12 and I don't feel that my Toyota is the best tow vehicle which would force me to upgrade to a full size truck thus more cost. Towing capacity is really under 1500 pounds if that with the Toyota. My area has a considerable amount of weekend warrior types with consumer or worse grade 21' mowers and a truck. It's important to me to distance myself from this class of operator but yet remain competitive by getting the work done quicker and providing superior service. I work another home business that covers my basic expenses so paying for a Quick 36 by summers end is extremely likely. I'm gaining roughly 1 client every 2 weeks or so with just newspaper ads this late in the season. How big of an area would one need to be regularly mowing to justify the extra speed of a decent commercial riding mower vs. the Quick 36? Maybe that a question for another post. Any input greatly appreciated.
