i bought my l59 at an auction, it didnt come with the bracket to attach to my super a nor did it come with the belt pulley. i bought the big bracket that blots between the final drives for about 60.00. the pulley is what was so expensive, it cost me about 80.00. then a week later i saw the same pulley on ebay for 10.00. the woods part numbers are:
the big bracket (idler and mounting bracket assembly) - 9238
2 small pulleys for the bracket is (v- idler sheave with bearing) 4336 X's 2 (need 2 of them)
then the belt pulley and adapter piece (drive sheave 9.4 p.d.) 1481 and then the bushing is (bushing with bolds) 3651.
these are all the part numbers and there descriptions. i have the parts breakdown page for everything you need to bolt it up. there are some other pieces that are usualy already on the mower, but if they are gone you will need to buy them also.
if you want i can try to scan the 2 pages of my manual. 1 page has a drawing, and the other page has the part number and descriptions. believe me it makes it alot easier to mount this mower with the corect pieces. otherwise you will end up chewing up a 50.00 belt twice a year because of alignment problems with homemade brackets.
i can also give you the number to my local dealer who could order for you if you dont have a local dealer or your local dealer wants your first born for the parts.
my dealer is Abingdon Equipment Co.
