    In the hot summertime, some of my Walker's burn spots in the yard when we stop to empty the grass catcher. The grass will green back up in a week or two, but it is an eyesore. Has anyone else had that problem? I have considered getting an elbow and welding it to the end of the muffler to make the air go up instead of down.

    If the exhaust on my machine was burning the grass while I unloaded the bag or bags and if I wanted to continue to bag my choices are: stop engine to unload bags (too much trouble each time) or extend the exhaust into a different direction.

    It is called poor engineering by people who sit inside ac room without even going and cut real grass. Computer program geek doing drawing and such but have no real hands-on experience, what on earth, very dumb design to burn grass by exhaust when stopping!

    home depot, one 45 degree steel coupler that has screw tighteners on each end and a 4" piece of steel piping same size as the originaly exhaust, put that on the end of the original exhaust and that should help i would assume i did that for one of my lawn tractors years ago, that was to make it look like it had a Mack Truck Stack exhaust though!!.....i agree though, poor designing.

    Walker has a new muffler kit that eliminates the problem. The muffler update was primarily done to eliminate the after shutdown 'bang' of the kohler but also seems to avoid the burning grass problem. The potential under certain conditions to cause grass burn has been addressed in the past by notes to dealers. What I have to ask is how long have you had these and when did the problem first occur?

    By the way, to those comments regarding engineering, Walkers are engineered by 'hands-on" guys who are in the shop and field, not design board weenies! These are farm boys who love to tinker and in the process came up with a great product. They value feedback and have proved responsive to suggestions where practical. Improvements don't take years to be implemented.

    wow never heard of that, i can't believe that just stopping for a few mins would burn the grass.

    Walker is facing extinction down here, nobody uses them, the ones being used are so old and worn out. They need to come up with products that sell like Hustler, Gravely, Ferris, Kubota, DC, Toro/eXmark, JD, and Scag.

    I real time it only takes a few seconds to burn and or kill vegetation with an exhaust pipe. I've heard of flower beds being damaged from the exhaust (heat) by making a slow pass by.
