SOURCE: Husqvarna Mdl YTH2448 Riding Mower - Electric PTO Not Working

It sounds like your charge system is not working. If you jump the battery the engine will run with a weak battery but the pto clutch needs a strong battery to stay engaged.Try this to test it,after you jump it leav the jumper cables hooked up and try to engage the blade clutch,if it runs it is either a battery that wont take a charge or a charge system not working. If you put a volt meter on the battery while the engine is running and the voltage is 13 volts the charge system is working and the battery is bad.

SOURCE: i have a bolens 38 inch riding mower. it cranked

did you try depressing the clutch to disengage everything regardless of being in neutral? and it sounds like a pulley bearing went bad.try to spin the pulley with your hand and see if it moves.take the belt off to the mower deck and that should keep them from turning when you go to start it.

When running the mower, it shuts off immediately when trying to engage blades(pto)


Hi Digger:
I've two possibles come to mind for you to check.
1) Engine OFF - Make sure that all of the blades and pulleys can turn freely.
2) Engine OFF - Double check belt routing. Move engage lever ON/Off and look at what movement happens. It may be that the belt is on the wrong side af a mounting flange and binds when engaged.
Cheerfuls.

X520 jd mower trouble


Sounds like a problem with the governor. Start it up. Don't engage the blades. Drive to a hill. Idle all the way down. Try driving up the hill. The motor should pick up when it slows while pulling up the hill. If it doesn't, the governor isn't working right.

Craftsman ZTS 7500 dies when engage blades or when engage transmission


check the "kill switch" they are usually located in the seating area. it senses for pressure or seat angle and will kill the mower if nobody is sitting on the mower. Good Luck

Husqvarna 17530 stalls when engaging the blade. Seems to run fine else wise/


Does engaging the pedal for the PTO lug the engine down, or does it just die like turning off the key?
If it lugs the engine down, then you need to make sure you can spin the spindle and idler pulleys by pulling the belt by hand. You should be able to slip it around the engine pulley enough with the blade pedal disengaged. Pull the belt up tight so the slack is around the engine pulley and try to spin the blade spindle and idler pulleys.
If it dies like turning off the key, then its likely a safety switch and may require a meter to test which.

The seat switch is has a shunt in the circuit that must be satisfied in order for the rest of the circuit to be happy. Make sure the connections are good, the pins inside the amp connectors will sometimes spread, push out of the lock etc. and if connection is lost will not work. Otherwise a new seat switch will be needed. You might check the PTO switch for continuity, without a diagram or schematic I am not sure how your circuit is wired. you have to have the parking brake engaged to get off the mower while the engine is running and the PTO is Dis-engaged?
I don't know if your "go" pedal eliminated this switch or not. But if with the parking brake engaged and the PTO disengaged, you lift off the seat and it dies, then its the seat switch.

Hope this helped Tim

Mower deck shakes when PTO is engaged


An imbalance is causing your vibration. check the blades. You probably have a bent or damage blade. Could also be a bad spot on the deck belt or a damaged spindle.
Good luck.

Replaced belt for mower thought i put it all back correctly blades engage when key is turned engage lever to off what did i do wrong


If you look at the motor pulley area, there should be two different pulleys with a PTO clutch between them. The PTO clutch has wires going to it, because it is operated electrically by the blade engage switch.
It sounds like you could have accidentally put the mower deck belt onto the main drive pulley (which turns all the time) rather than the pulley that is farther out from the engine, which only turns when the engage the blade switch. If so, just loosen the mower belt and move it to the right pulley.
Good luck!

When I engage the front PTO the engine dies.


There is somthing in the PTO that is binding up. I am assuming the PTO is for the mower blades. The belt(s) could be binding up, not on the pulleys, etc. The blades should turn by hand easily.

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.
