Another caveat of the Timemaster is you certainly cannot mow your lawn twice a month and hope to have good results. If you try and mow really tall lawn you will either clog the mulching, fill the bag in 2 seconds, or have piles of grass side discharged. If you mow once a week or every 10 days, like your supposed to, in dry grass, even the old 190cc model is enough. The bigger engine is better power wise but worse fuel wise because the fuel tank wasn't enlarged. Sometimes i would mow twice a week, but i like mowing, and cutting a small amount side discharge makes the clippings invisible. My new place has a green waste can so i typically bag 4/5ths the time with an occasional mulch for nutrition sake.
