BELT WON'T TURN

You either have too long a belt or it is routed incorrectly. Do a Google search for you make and model deck belt routing or look up on jackssmallengine.com

Looking underneath the mower on top of the deck there should be a flat metal arm with a flat faced pulley on the end. This pulley pushes against the belt that drives the mower deck . The spring should be hooked on that arm and pulled tight over to a place on the deck and this is what keeps the belt tight enough to turn the blades when you engage the pto switch. My recommendations to put this back on is to remove the belt pulley cover on the deck right side roll the belt off at that pulley giving you a bunch of slack so you can hook up the spring and put the belt in the right position on everything else then go back to the deck right hand pulley start putting the belt back on that pulley and when it is to tight to get it all the way on reach under the deck and use the blade as leverage to finish turning the pulley and walk that belt on the rest of the way ,it will not hurt a thing, all you are doing is pulling that 7 inch spring over like it was intended to be, then replace the cover on the deck spindle.

Before you try to start it up, Make sure Your PTO and Deck levers are in neutral.

If it's for the deck there's a rod on the deck you pull out to release the tension. If your drive belt you have to take the deck off.

well usually when this happens it;s a safety switch that's defective or misadjusted but your sure these are good Id try dropping the mower deck and try enguaging pto if it still runs you got a deck problem ,I have seen spindle bearings lock so tight that it'll stall a 46 hp tractor but that was a brush cutter deck

check fuse to pto dose pto click when you start the swicth could be that safty switch has come lose keeping pto from operation take off belt and by pass switch to pto see if it activates what you want to make sure pto didnt burn up im more thinking it is a relay gone bad or a blown fuse

Park brake switch is the most likely culprit,any other would cause the tractor to not turn over in the crank position.

The first thing to check is the fuse,it should be located underneath the battery.

check the 2 wire conection under the frame near the pto clutch, motor off of course. Make um tight.

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.
