Great service from you guys, really appreciated it - my old (1991) model Murray mower is still running fine, (one his third mower deck and probably 10th set of blades!)
I needed a left hand headlight lens (part 91319) but so far haven\'t found one - got the right hand lens and all the other parts aok, so looking forward to the winter overhaul in the shed - if anyone has any idea where I can get the lens I need, new or second hand, would be great to hear !

Cheers
Kelvyn
