So I bought a house, and I needed a riding tractor to deal with the 1/2 acre of grass (and growing, as we're clearing the brush that has grown up). So I got one off the want ads for $150.

I've got a few questions, making a long post.

It ended up being a Simplicity 4211H. Near as I can tell it's Post 1984. (I don't know how long they made it, but it was introduced in 1984)

It runs good. I'm hoping to improve it a little bit, and getting my money's worth out of it.

It's a 11hp B&S I/C motor. (I can get the exact model and engine code, It's at home, and I'm at work)

It's blowing smoke when it runs. Blue Smoke, usually means oil.

I know it's not because the engine is overfilled, it's just burning it. (I know cause I have to fill the oil up)

The previous owner told me it's burning oil, at the rate of about a quart (or less) a month. I'm assuming that's running it every weekend. I checked the oil yesterday after running it, and it looked pretty bad (as in not the color I expect oil to look), course I did it at dusk, so I couldn't get a good look at it.

Is there any kind of oil treatment I can throw in it that might "help" out the motor? (Something along the lines of slick 50 or ??)

The next question I have has to deal with the motor in a limited way.

When I engage the PTO, the blades spin up to speed. If I engage the transmission quickly, the blades slow down (leading to the grass to clogging in the bagger)

If I engage the transmission slowly, and slowly work up to speed, this doesn't happen. Is this the motor not putting out enough torque, or just an idiocracy of a 23 year old Hydrostatic motor.

Final question. Since I just got it, I have no Idea what "normal" maintenance has been performed on it. Previous owner said he had a friend that ran a Small Engines shop worked it over every year. The friend closed up shop, and the owner decided to dump the mower. I did ask when the last time the blades were sharpened, and he said last year.

So I know I have to: (Since I can't tell when the last time was)

Sharpen blades

Change Oil

Lubricate mower deck (He gave me the owners manual, and it says to do it.)

New Plug

What else should I do? The owners manual says take it to a "Simplicity Qualified Repair Center for an Annual checkup" I'd rather just check it out myself.

Does the Transmission need any attention?

Does this engine have an oil filter, or just an air cleaner?

Thanks for reading a really long message.
