Question
Hi i have aquired a Noma 1635 signature lawn tractor and need to replace the belts and possibly some other things.  Would you know if a parts list or manual is available, or part numbers for the belts?
Model # - G4316130
Serial # - S001220337778
Code - 6052

engine is 16HP Vanguard
Model # - 280777
Type - 0636 A1

Answer
Brad,
Noma was bought out by Murray several years ago. Now Murray sold to B&S and all the older stuff isn't available in paper as far as I know. A Murray/Briggs dealer should have the breakdown. If they have it on PartSmart (computer) they may be able to print you a breakdown.
Thanks,
Keith
