Our company has a 48" and 52" Lesco WB, both with 17hp Kawi's, for our local parade, we put our Velke on the shinier 48" and left it on today to mow, WOW! I am not sure if it is a different type of blade, or the extra power of turning only 48", but I can seriously cut WIDE OPEN, full speed PERFECT! The 52" always rolled the blades over if we went too fast, the 48" can go all out! I am just curious if anyone else has seen this, I am pretty excited about it! I almost feel like I'm on Eric's jet-powered Dixie Chopper!
