Be sure the belt is the correct size and is routed correctly.

If you are not sure, you can download a manual here:

You will need the model & serial numbers.

SOURCE: loud screech noise from deck area

This can be due to a belt slipping or a bad spindle bearing.
And on the difficulty scale,10 being extremely difficult, The belt would be a 1 or 2 and the spindle about 6 or 7 (because the deck usually needs removed for this job)

SOURCE: Craftsman 42" mower deck won't disengage

Try pulling on the cable coming down to deck. This cable might be your problem. Also check that the spring on the end of this cable is present and functional.

you have a safety switch malfunctioning or a transistorized relay not working properly. Go to www.partsdirect.com, this is sears website. It should be able to find and illustrated parts list for your mower.

A PTO that is engaged constantly,


On that type PTO engagement there is slack in the belt that disengages the deck, in some case there is a arm with a idler pulley that swings against the belt to tighten it and engages the deck , in other cases like older MTD:s the deck swung backwards as it was let down and tightened the belt and was lifted to turn it off. Most of the decks had a brake of some kind on the deck pulleys to stop freewheeling of the blades when disengaged .

Where is the safety switch to engage the blade


Your lawn tractor will have a lever that raises and lowers the mower deck which houses the two cutting blades. By lowering your mower deck to the desired cutting height, the blades should automatically engage. By raising the deck back to it's highest position, the blades will automatically disengage. Should be simple enough. You can consult your mower manual. If you don't have one, you can easily find it online using the make, model and year of the lawn tractor.

I have a 42" mtd lawn tractor. The blades do not


The blades engage via a belt, that goes around a series of pullies, one of those pullies is a tension pulley that is connected to your pto lever by springs, the engine has nothing to do with your blades until after you engage the lever, I would check your belt. It could be loose, and if you engage the blades it could take it a few to get up to speed, thus making it seem like its only when the engine is warm.
Does everything else work fine? As in the tractor moves when the blades are not engaged?

When you say nothing happens...is the PTO engaging? You said that you already checked the belts...if none of these are off...you maybe looking at a new PTO clutch.www.nnyparts.com

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.

    I need a belt diagram for a ranch king king plus also i need to know the size for the main drive belt


    Ranch King is a brand name of the manufacturer MTD.

    Product manuals with part blow-up diagrams are available from MTD's web site,
    http://www.mtdproducts.com/
    Models are identified from the model number printed on a label under the mower seat.
    The PTO and deck drive belts are shown on one diagram and the transmission drive belt is shown on another. The Form number on my printed Operator's Manual is 770-10526A (22HP, 46in cut) for Hydrostatic 817/818 models.

    Parts can be ordered directly from MTD or other distributors on the web.

    It is my experience that original brand name MTD belts work best.

    The 22HP, 46" mower deck Ranch King Pro has 3 belts:

    The drive belt which runs from the engine pulley back to the hydro drive unit to provide over-the-ground propulsion is part #754-0349.

    A mower has either an electric PTO or a manual PTO, not both.

    The electric PTO belt the provides power to the blade deck (runs around the electric clutch on the engine shaft (activated by electric switch, not the mechanical hand lever that engages the mower deck) is p/n 754-0476 for the 46" deck.

    The manual PTO belt the provides power to the blade deck (runs off the pulley on the engine shaft (activated the mechanical hand lever to the left of the steering wheel that engages the mower deck) is p/n 754-0228 for the 46" deck.

    The deck belt that goes around the 3 blade spindle assemblies on the mower deck, to drive the grass cutting blades is p/n 754-0349

    In my experience, the PTO belt lasts about half a season, the other belts break about every other season when mowing 4 acres weekly.

    I have a craftsman riding lawnmower and the blade engagement is not starting the blades when i lift it. It feels loose when i lift it.


    Sounds like you PTO cable is broken. Part # 175067. It goes from the lever on the dash down to a deck mount and hooks to the idler pulley. When you lift the lever, it should pull the pulley and idler arm towards the rear of the deck to tighten the belt to engage the blades.
