Recently I have purchased the Lazer HP 52" with 23 Kholer. The quality of cut is fantastic and keeping your hat from blowing off in the wide open is hard to do! A very productive machine. I do have a question. Just curious, what is the purpose of the offset in the frame structure? The front casters seem to be to the inside of the left rear wheel and outside of the right rear. I have noticed that on slight hills when the right side of the machine is to the top of the hill, the right front caster is sometimes off the ground. The left caster is always on the ground. Yes, I have checked tire pressure and all is normal. This Is posing no problems as far as the quality of cut or the manuverablility of the machine. It's just driving me nuts that I cant figure out why they are offset like that. Is there a purpose for this?
