I am having trouble with my exmark metro 36 with the mulching kit, mulching blades when trying to mulch up extra leaves...This is a "true" mulch kit and has the baffles..From the driving point of view, it seems like the left side of the deck will create vacuum pretty well and catch most of what it goes over, however the right side (originall the discharge side) will swirl the leaves and shoot a percentage out and into the next pass. Sometimes I have to go over a single line of leaves several times because it keeps shifting some to the right. What is the cause? & What is the fix? I'd love for it to vaccum them up as well as it does on the left so when I go over a pass it gets all of the leaves in that pass and I can turn right around and hit the next line without it blowing leaves back into the already cut & mulched area... Any help is greatly appreciated. It would save so much time.
