Ok, so I read some of the other threads about some blade issues. However I'm still not sure where to look for better blades. I did my research and I may be looking in the wrong places. I have a craftsman 33" wb. I know most of you pros don't care for the brand, but it is a good mower for just starting out. The blades are two 17.9". Is there another brand that is better that I can use? When I am in 3rd gear it leaves stringers, 2nd is too slow. The blades are sharp, I checked...its brand new, used only 4 or 5 times. I only have 3 accounts at this time. Any input would be good...tks bruthas.
