Used a B&S engine. In the stamped engine info. Model type series & code. The 1st two digits in the code is the yr of the engine. Hence the year model of the tractor.

I bought a used 3312 about a year ago and it's been a good machine. Don't know about the S. Cuts well, but I don't use it for much other than cutting the grass (sometimes as much as 2 acres) and hauling a garden cart. It's definitely a lawn mower in my opinion. Mine was built in 1990. I replaced the wheel bushings, a set of blades, and a mower deck idler so far. The B&S engine starts quickly and doesn't burn oil. Don't know what the previous owner had to do. I've put about 75 hours on it since I've had it.

I have the same mower, new since 1993, I still use it today. Its defiantly no garden tractor but no problems in nearly 18 yrs. Do you have any info where you can find a bagging system?

I've never thought about using one - just let everything fall where it wants. I'd start looking at a shop that still services Troy-Bilt Equipment. You might get lucky and find something that can be adapted.

I just picked one up, too. 3312grs, s/n B380101388. In a package deal. Real 'quiet' engine. Uses absolutely no gas. Pushes easily. Nice big hole behind the starter, in the engine. Bummer. Previous owner ran it without oil. Missing the engine compartment side panels, but no rust anywhere. Has the mower deck but missing the raise/lower contraption for it.

The 3312 is similiar to the Bolens 'Suburnan" ST-120, except for the color, Red vs. white & green.

The rear has the tiller attachment arms, and it has the 'tiller' transmission, whatever that is.

Supposedly made by MTD Products.

Parts manuals/lists are on the web. Operating manuals I have not been able to locate. Have not seen many parts for them on eBay.

I'm looking for a replacement 10 - 12 hp. vertical shaft engine to get mine going. Until then, it just sits.

Doh!
Cleaned the hour meter off on the TB 3312, it has 4,475.6 hours . Guess someone left the ignition key turned on. And, it looks like it's on it's 2nd motor, with the hole in it. #3 motor is being dropped off tomorrow.
