just started to have a problem with my mower. when i mow it leaves a path in the middle untouched.
any help would be great. thanks
Others posters here have suggested worn or incorrectly installed blades, and that is a likely solution. Blades are measured from sharpened point to sharpened point, and should be installed , when looking from underneath and from the front of the mower, with the sharp side of the blade on your right side.
It helps to think about how the two blades work together to provide a seamless cut. One blade is mounted slightly ahead of the other so that the blades can't touch, but the blades' cutting paths can overlap. Now picture the mower taking a right turn then a left turn and imagine how that might affect the relative position of the two blades to the path of the tractor. It helps to think about the cutting paths of the blades as circular pieces of plywood.
