Completely rebuilt the deck, everything was worn out.

Dissembled deck completely and reassembled with new parts. Diagrams that came with parts were very helpful. All parts fit better than new. Deck cuts better than ever. I saved a lot money.

Nothing ! - got the parts for my winter overhaul yet to be done

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
