Mtd ride on mower cutter blade belts smoke when engaged

How is the drive belt?

ed, be sure there is nothing wrapped around the blades. lower the deck and be sure the belt is around all of the pullys. If the belt comes off one of the pulleys or the pulley on the engine it may feel normal but it wont engage the blades.

Sounds like your mower belt needs to be replaced. Good luck.

You have probably thrown the belt for the blades. If it continues to throw the bet check the tensioner.

Have you physically moved each blade by hand (with the machine shut-off),spark plug disconnected to see if both or all of the cutting blades move freely if there is any binding you probably have a bad blade spindle bearing . If those move o.k. then you're going to want to check the pulleys on top of the deck, one of these which do not go to the blades may possibly have a bad bearing and is not moving freely causing the belt to be burning up.

.... burning rubber smell? Sound like you have done a cutter belt.

My idea is not about the belts, but is about the deck. If the tensioning mechanism on the deck is getting stuck in an intermittant position than the belt may be just tight enough to turn blades while slipping through the pulleys, this may cause enough friction to start melting your belts. If this is the case you will have to remove your mower deck and see what is preventing the mechanism from functioning properly.

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