Hi there, how much would a cutting deck plus belts etc be for a viking mt640? Looking at purchasing one, however does not have deck. Is 250 a fear price for the mower minus deck? Cheers

This page has some dimensions of belts.

There are several YouTube videos about replacing belts on a Murray.

Jerry, could be a bad belt, pulley, blade,etc. Take back to place of purchase for repair under warranty.

Hi there,
I assume you mean the blade on cutting deck?
Is the pulley that drives it still firmly connected to it? (I mean the pulley and the blade spin together as one, and not independently)
If the blade is loose on its spindle check under the deck for damage, and that the blade securing bolt(s) are intact and tight.
If the problem is that the pulley isn't getting driven by the deck belt, that is a different story. Most likely the deck belt isn't getting enough tension to grip the pulley. Check the tensioner is working properly and the spring is still hooked up and working.

how to remove bearings on viking ride-on cutting deck

I think I have a diagram for this, what hp is the mower 12hp? what size cutting deck? I have an old roper 12hp which needs a new belt but don't know what size belt to buy?

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.

Hi Matt,

Thanks for the update. Good ole brainstormin' comes through again!

From the motor pulley it goes inside the 2 idler pulleys, and then outside the drive pulleys.
Although near on 2 years on, I hope you figured this out already...
