Most likely the mower belt is rubbing and causing this. But don't try to find it with the mower running! With the engine off, lower the deck and inspect the mower belt for worn or burnt spots. The problem isn't the belt, though. Look under the mower deck - is a branch or other object stuck in there? Get it out, and replace the belt if it's badly burnt.

If it's not a stuck object, than you probably have a frozen spindle (the bearings that hold the mower blades) or idler pulley. Remove the belt and spin each of these by hand to find the problem. The pulleys are not expensive, but the spindles are. I hope it's just a branch. Good luck! Please rate if helpful, thanks!

SOURCE: white smoke coming out of mower

It sounds as though you are losing power (electrical power); see if charging the battery fully allows it to run longer or if charging the battery helps.

Mower blades won't engage


Did the smoking stop when you disengaged the blades? If so it is most likely your belt that is smoking. Make sure all the blades turn freely by hand to ensure you have not hit anything that may have bent a shaft on one of the blades. If one of the shafts is bent and wont turn FREELY, the belt driving the blades would slip and start smoking as it tried to turn them.

This sounds like a micro switch acting up, the first switch to check is the seat switch, make sure the block connecter is pushed fully home on the switch ( there is often a fail safe inside the connecter should the block come away from the switch )

Husqvarna riding mower smokes when cranked and dies when engaging blades


If it dies when engaging the blades it's not getting enough juice to do so. Test the battery and make sure you are getting at least 12 volts. If not, charge it. If so, the solonid is going bad.

Smoke when blades engaged on yardman 42'' yard tractor


The oil on your pulley could definitely be the culprit. You need friction in order for your belts to work properly.

Engine only runs at low idle and smokes


Hi,
So now, without the blades engaged, it smokes and then dies?
In your first description it sounded like the engine was under a strain. Overfilling with oil could produce a strain, but since it ran ok until you said you engaged the blades, I would have to ask if the blades themselves, were causing the strain. Sometimes if you cut wet grass, the clippings stick to your underside of the deck and can really build up. Also some rope, wire or twine would around the spindles could creat one. Check this out...
Now, with the "smoke" issue (I'm assuming a blue smoke from burning oil) I'm inclined to think your rings aren't compressing any longer and you're burning oil. You might be in for a rebuild... I hope not.

White smoke and blade won't engage


Sounds like a low compression problem. The piston rings have most likely failed and oil is seeping past them and burning, thus the white smoke. An engine needs three things to run...Spark, Compression, and Fuel. Just take the mower back as it is still probably under warranty. Mike. Rate 100% please.
