As I stated earlier - the timemaster is no good without modification. After modification - it's all I use on the residential properties where I live. It's way better than a Toro recycler. I have a brand new commercial 21" toro recycler and it sucks big time compared to the timemaster after modifications. The recycler bogs down in everything and I spend more time stopping to let it breathe than I do actually mowing the lawn. Also bear in mind that we side discharge all of our lawns (recycler doesn't offer this option) and with the timemaster we fly through properties in half the time. It never bogs down, it discharges beautifully after the blade mod/discharge chute mod and we can have 2 people running 2 - 30" timemasters to replace 3 people running 3 - 21" mowers. Not to mention the fact that you can actually use it at nearly full speed with no bogging and it leaves a perfect clean cut. From the factory the blades are horrifically designed. You should notice right away that the blade are angled downward from the center towards the blade tip; that is to say that if you ran your finger from the blade tip to the center bolt you would gradually be moving upwards - this in and of itself results in a downdraft instead of an updraft and sends clipping to the sides of the deck instead of up in a circulating motion through the deck. After no time at all the deck becomes clogged with grass and the airflow becomes null. First thing you need to do is straighten the blade so that the tip and the center of the blade form a straight line. The second thing you need to do is twist the blade so that the blades have more lift (I did this with a sledge hammer and a strong cement block by placing the blade on the edge of the block and giving it a few hard blows while I held it down with my foot). The side discharge chute is horrible with a giant piece that obstructs the chute. Cut this out with a grinder or similar tool. I also shortened the chute as most residential chutes point downwards for safety and this is not what you want in a commercial unit as you want the clippings to disperse as much as possible to prevent clumping/piling of grass. Do this and obviously as with any mower make sure the blade is razor sharp and you're cooking with fire. I have attached some pics I took today of the cut quality. No stragglers.
