forgive me if this is "common knowledge" on one of these sites, but i tried to google for an answer to this and came up empty. i just joined to try and satisfy my curiousity.
ill try to keep this short. i have a 21" craftsman mower, with the star hole, that nobody seems to carry blades for. went to homedepot, lowes, and even sears - no luck, so i just bought a replagement oregon blade online. ANYWAY - my question is this - can i use one of the blades from a twin blade 42" tractor on my 21" mower deck?
while in sears, they had no 21" bades with the star hole, but they did have a twin pack of blades for a 42" tractor. they were basically identical in length (to within 1/8" to the 21" blades that were in stock, but were different "types" of blades so im guessing that would account for any minor difference) . the cutting edge was actually longer on the tractor blades than any of the other single packs, but the shape of the blade was different. where the 3-in-1 mower blades had more of a smooth transition from the "low to high" cutting height, the "premium" tractor blades were kinda "stepped" in height. the tractor blades were advertised as "mulching / discharge" , which would lead me to think thats also a 3-in-1 type blade.. lastly - cutting edge on the tractor blades didnt seem as sharp - so im not sure if thats cause they dont need to be, cause its a much more powerful engine spinning them, or cause they would dull too fast if they were "knife sharp" as opposed to "axe sharp" with all the extra land tractors are used to mow..
i walked out with nothing, and decided to buy something online and have more of a choice..
anyway - just curious. thanks in advance
