The EGO POWER+ 42" Riding Mower Mulch Plug is designed to deliver the mulching performance of premium gas. This mulch plug is specifically created for use with EGO POWER+ Z6 Zero Turn Riding Mowers (ZT4204L, ZT4205S) and the POWER+ T6 Riding Lawn Tractor (TR4204). The mulch plug tightly seals the discharge opening on the Z6 Zero Turn Riding Mowers and T6 Lawn Tractor to recycle the lawn clippings into the 42-inch blade area for a clean cut to manicure your lawn with fine mulch clippings. The riding mowers feature a 3-in-1 function that delivers a mulching, bagging, and side discharge solution to replace premium gas riding lawn mowers for good. EGO parts are designed to offer the highest quality, performance, and value.
