They bring very good questions. I will do my best to answer them.
1. Not knowing how many sheets you use, the best way to keep the engine crankshaft, is not protected by mower belt. For the protection of stone knives and axes roundabout can be cut to the key roles? But that may take some time.
2. Get that corresponds to their axles Arbor. Do not luxurious curves are a pain to sharpen. Get the edge, the flat is.
3. The best way to solve would be to adjust the deck of your car. In this way, if you go, even if you do not play with them. Then attach the wheels to operate the bridge for the better.
4. Most small engines run at 3400 rpm. Here in the United States who can go the speed of the tip of the blade raised 19,500 feet per minute. This means a sheet of 20 "can be min 310 rpm, a blade 21-inch sheets go 295 rpm and a sheet of 282 rpm, 22-inch panels.
Hope this helps.
