Tankman 3,514 #1 Posted August 3, 2012 My '73 12 hp, automatic, Model 1-0465 has a 42" (?) three blade side discharge mower. I think (?) it may not be the 5-1010 deck which would've been original. I did paint the deck, lube wheels, replaced belt, all's well so far. Runs fine. Ordered a new decal set to complete the project. The deck, unlike the documentation, has the two wheels adjustable with the hand lever. Then, who knows? Rear of the deck has two [2] rollers, diagram shows one. Front of the deck has three [3] rollers, diagram again shows one. Is it possibly a modified deck? Or, I'm guessin' again, not the 5-1010 I thought it was.

Don1977 604 #2 Posted August 3, 2012 Later model if it has the original spindles you could go by that. If it has Double D spindles it could be 75-42MSO1 . Then they came with 3/4" keyed spindle for the pulleys don't know what year they changed. The newer decks came with Metric spindles the pulleys are 5/8" bore with out keys.
