This is a Briggs & Stratton Original Equipment 491588S Air Filter Cartridge. The purpose of this filter is to prevent dirt, dust, and debris from contaminating the carburetor and damaging the engine.

This is a shoulder screw that is used to secure the handles of yard equipment. Typically, this screw is used with a matching wing nut, which is sold separately. Many different varieties of push lawn mowers have handles that fold downward for ease of storage. This is one of the locations on a mower where one will find shoulder bolts and the point at which these bolts are most likely wear out. While they are made of durable machined metal, shoulder bolts receive a great deal of wear, particularly from the handles being raised and lowered each time the mower is used. When pushing down on the mower to clear wet grass clippings or to make sharp turns with the mower, the entire weight of the mower is put on the two shoulder screws where they intersect. Since the metal of the handles can turn at that juncture, extra shearing action is put on the shoulder bolts, which can wear out. It is actually advantageous that the bolts wear out since otherwise, the handles themselves would warp and break apart. These OEM genuine replacement parts fit a number of different lawn and garden machines, including many made by Cub Cadets, Husky, Troy-Bilt, Craftsman, Yard-Man, Bolens, MTD, and Yard-Machines.

This air cleaner cover is designed to house the air filter on larger lawn equipment and other outdoor power tools. There is no aspect of small engine care more necessary than protecting the air that goes into the carburetor and cylinder from yard dust. Nothing is more incapacitating to a small engine than being clogged with dust, pollen, and other particulates that are invariably stirred up during landscaping work. While the air cleaner cover itself is not a moving part and would not seem to be subject to replacement, it is occasionally the case that, through extensive use or accidental contact, the cover becomes unable to shield the air filter within it. In these cases, it is essential to replace the cover with an OEM certified replacement cover that has been manufactured to the same specification as the original. Though replacing the cover itself is quite simple, it probably a very good idea to replace the air filters at the same time. If the cover is in need of replacement, it is quite likely the filters have been exposed to excessive amounts of particulate. This cover can be used on chippers, shredders, log splitter, mowers, and a variety of other small engine/large job equipment. Compatible brands include Troy-Bilt, MTD, Yard-Man, Yard Machines, and Cub Cadet.
