I am wondering if anybody knows exactly what models of twin-cylinder tractors they had produced in the years 1978-84?

 

I know the 148-916A (4-speed transaxle), 148-918A (variable-speed transmission, aka "Sixteen/Four") and 148-995A (hydrostatic transmission) were the first three when they started doing these late in 1977 for the 1978 model year, however the twin-cylinder was also available for vertical-crankshaft applications (401700 series), and I am guessing the 760, 780, 820 and 830 series were the first such examples.

 

I know what the engine model/type numbers are for the 1981 and older machines:

401417 0126-01 = for all 16 HP horizontal-mount tractors with any transmission except hydrostatic

401417 0131-01 = for all 16 HP horizontal-mount tractors with hydrostatic transmission only

 

401707 0134-01 = for all 16 HP vertical-mount tractors with any transmission except hydrostatic 

401707 0135-01 = for all 16 HP vertical-mount tractors with hydrostatic transmission only

 

421417 0146-01 = for all 18 HP horizontal-mount tractors with any transmission except hydrostatic

421417 0143-01 = for all 18 HP horizontal-mount tractors with hydrostatic transmission only 

 

1982 to 1984:

 

401707 0630-01 = for all 16 HP vertical-mount tractors with any transmission except hydrostatic (1982 only)

402707 0155-01 = for all 16 HP vertical-mount tractors with any transmission except hydrostatic (1983 and later)

 

Thank you,

Man, YOU seem to be all up on these, so why are we asking?  Needing a particular part or just curious?  Don't think you'll find any better info than what you already seem to know. Good Luck!

You may find some more info in the MTD manuals in our Manuals Section. There are several excellant MTD Shop Manuals. They are filed in atleast two places. Good Luck, Rick

I'm trying to help folks like you as well regarding this.

 

Apparently, the 421417 series was a one-year-only (1980) engine, so therefore any 918 or 995 from 1981 (as in 141-918A and 141-995A) would have originally had a model 422437 series engine with a type number under 0500.

Ive bought my first tractor and its one you've listed. 1980 yard man 18hp hydrostatic twin cylinders opposed Briggs and Stratton. Fairly impressive machine! Model 14995-0 serial 41-013-0291. I'd love to find more implements and a parts machine.
