Before anyone flames me I have searched using wide AND blades and have read for a couple of hours and haven't read anything pertaining to this. I have a 52" GDane Surfer that calls for 2 1/2 wide blades 18"long w/ a 5/8" center hole. Since I am fairly new to owning and maintaining a commercial mower I got taken not once but twice with dealers and local shops passing off med. lift blades as high lifts. Now that I know what a high lift looks like, I won't let that happen again. I had to tell a shop yesterday just to forget it when the guy first tried to pass off some med lifts and after I called him on it tried to pass off some 17 3/4" blades that I quickly measured to show him wouldn't work. Anyway, my question is this, has anyone used the wide (3") high lift blades? In the JThomas catalog they are listed as SG-B442 I believe; they are listed under Scag blades. I am talking with Oregon (Kevin) to find my state distributor and searching J.Thomas to find what I'm looking for and came across these. I wondered if they would give me even more lift that a 2 1/2 high lift. Also, do any of you guys use the heavy duty blades (.240 or.250 as apposed to .204 blade thickness)? Thank for any advice on this you can give.
