Up for grabs is a copy of the Master Parts Catalog for the Troy-Bilt Roto Tiller - Power Composter, dated 10/30/72, covering three models as pictured on the cover, specifically the 4 1/2 HP Standard Start, the 6 HP Standard Start, and the 6 HP with Electric Start, all produced from 1961 to 1972. IT DOES NOT cover the New Pony model Troy-Bilt roto tillers. Contains crystal clear exploded views of all parts of this tiller and parts list with numbers and description, including a few somewhat fair greytone photos of the engine and unit itself. Perfect reference material for disassembly and repair of this super machine. Thirty-one pages of complete parts breakdown. A necessary item if this is the model Troy-Bilt Roto Tiller you own. Shipping will be $2.50 via USPS First Class Mail Parcel in the United States. Thanks for looking and have a great day.
