Just picked up my brand new Walker 48" GHS MT26 mower today. Its got the wide, low profile tires, 9.5 bushel catcher, 26 HP fuel injected Kohler. This thing is awesome. I also got the dethatcher for it. The only mower I have used before is my 48in Scag belt drive walk-behind. I'll post some pics soon. I'm getting a ton of work and I just started my advertising 2 days ago. So far I got alot of new lawns plus last years lawns, at least 10 clean-ups, 2 landscaping jobs and that was only 200 of my 1000 flyers. Also got a couple people signing year-round maintenance contracts and expect 100% retention of my customers from last year. Any tips for this mower I should now? Is once down the lawn enough with the dethatcher or should I do it twice or cross cut for spring clean-ups?
