Hi, The most likely cause is a defective head gasket. They normally fail where the push rods pass through from the cylinder to the head. A new gasket is around 20 dollars and is a relatively straight forward job. I normally charge around 75 dollars in my shop to replace a single head gasket, about one hour labor plus the gasket.
If you do not feel confident doing the repair, bring it to a reputable shop. It will be done correctly. Then again, it would be a good learning experience. It is critical to have a torque wrench for a newbie doing the job. Torque the head bolts to 25 lb. ft. by progressively tightening little by little. always tighten bolts opposite of each other similar to putting a wheel in a car. Get them all up to about 20 lbs then finalize to 25. run the engine for an hour and recheck. DO NOT use lubricant or never seize on the head bolts. the torque figures are with dry bolts.

How do you fix a smoking lawn mower?
If it is a push mower there are only a couple things that will cause the mower to smoke. 1) The rings are worn and need replaced. This lets oil seep past the rings and burns the oil in the cylinder. This will cause a white smoke. (this is probably the most common cause for engines smoking) 2) The carburetor is putting too much gas in the engine. This will cause the engine to run rich and make a black smoke. 3) There is an external oil or gas leak that is leaking onto the motor and burning from the heat of the engine. If it is a riding mower there are many more things that could cause it to smoke.
