Is there a PTO adjustment?

My 1045 46' cut with the PTO lever engaged when we go to lowering the deck last or next to the last notch we do not hear the PTO engage until we adjust the deck height upward to the 3rd or 4th notch. Is there an adjustment? Thanks Alex

SOURCE: how to adjust belt tension 42" raftsman lawn tractor cutting deck

Note: This is about a different mower, but it might be similar enough to yours.  If not, please disregard.  Thanks!

I had a similar issue with our mower, a 2006 Troy-Bilt Pony model 13AN77TG766 (17.5 HP, 42 inch deck): when I pushed the handle down to engage the blades, it took a good ten seconds or so to start the blades turning; even then, they didn't have enough power to cut the grass.  And on any height setting lower than 5, they wouldn't turn at all.

The cause was on page 19 of the manual <URL:http://manuals.mtdproducts.com/mtd/DocGetter?doc=769-02243a.pdf>: Figure 17 shows the "PTO" cable attaching to a hole on the edge of the deck idler bracket, but it was shipped from the factory attached to a hole in the middle of the deck idler bracket, about 3 cm (1 in.) closer to the front end of the machine.  I reattached the cable to the original hole, and the belt is now good and tight; the blades engage as soon as I push the handle down.

Now, today, I'm having problems with the belt popping off the right-hand idler (hopefully just needs the deck stabiliser rod adjusting).

Always remember to remove the spark plug wire before you go near the blades; and watch for hot, sharp, and/or pinching surfaces.

Good luck!

SOURCE: Cub cadet Z Force 48 inch zero turn blades won't engage

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.

SOURCE: 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.

SOURCE: cub cadet pto won,t stay engaged

Sounds more like a PTO clutch failure, rather than the switch. The clutch is mounted on the engine shaft, between the hydrostatic drive pulley (nearest the chassis) and the mower deck belt pulley (farther from the chassis).
Since it's an expensive part, make sure the problem isn't in the switch or wiring first. You could do that by probing the wires to the PTO clutch with an automotive test light - they are inexpensive and handy. Clip the ground wire of the test light to the chassis, and probe the hot wire to the clutch (it's the one that doesn't connect to ground) when the engine is running and the PTO switch is engaged. Obviously a helper has to be in the seat, and you should be careful doing this. If the light glows brightly, and the clutch doesn't engage, you definitely have a bad clutch. Good luck! Please rate my answer if helpful, thanks.

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 do i attach the PTO deck engagement spring on the cutting deck of the 2009 cub cadet LTX 1040 PTO deck engagement cable attachment on the cutting deck


Wherever it was that you took it off from. If it broke, then look to see where a spring might be while you have a friend slowly engage and disengage the assembly. If it's an electric engagement situation, bring it to a shop. If you don't have a friend, sorry. I'll be your friend.

Sears troubleshooting


It is likely that the pto engagement cable has broke and needs to be replaced. Lower the deck all the way down. With the engine off, kneel on the right side of the mower. look under the mower and find the end of the cable on the deck. It will be near the center rear of the deck and will have a spring on the end of the cable. Once the cable is located reach up and operate the pto lever and watch the cable. The end of the cable should move with the lever, pulling the idler pulley back and tightening the belt. If this movement does not happen replace the cable.

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.

John deere 855-70 manual


On ALL Deere riding lawn mowers, 1st, position the deck under the tractor. Depending on the belt drive: either PTO (the yellow button on the dash panel), or tension engaged-(a lever on the right side of the operator\'s seat), you loop the drive belt from the front of the deck to the pulley, always in the lower front area of the tractor\'s engine. If it has "beltguards" too close to the pulley, you must loosen the retaining bolt for the guard, it will allow the belt to squeeze by and onto the pulley. Then, 2nd but don\'t forget to retighten after slipping the belt on, push the "Deck heighth" lever fwd to drop the deck "hangars" at the rear of the deck into position to "pin" the eyelets with the supplied pins, washers and keepers: usually a cotter pin or a lynchpin that inserts thru a hole on the smooth bolt-pin. The easy part\'s over, but don\'t panic. 3rd, lift the front of the deck onto a block, allowing a heighth to apply the "adjusting rod" into the front of the mower chassis. Screw the retaining nut onto the threaded (long bolt) and remove the block. You\'re done. Next, and very important, RAISE & LOWER the deck, engage the belt tension, (here you may have to clear the area and start the engine to engage the PTO drive, if it\'s electronically controlled belt-drive), this assures nothing is "misaligned" or improperly positioned. Now, if the machine is on a flat surface, lower the deck to a point just above the ground and measure the distance in four (4) corners of the deck and record the ht. Make the adjustments to LEVEL the deck. Now you\'re ready to start the engine from the operator\'s seat, slightly increase the engine from idle to 1/4 throttle speed so that engaging the drive belt won\'t kill the engine. Ensure the belts run smoothly, the blades turn, and the engine doesn\'t "bog". Lower the deck to a desired cutting ht., now MOW the grass!

On my 42in cut hydro. Husqvarna, The mower will not disengage until the speed is reduced to a low idle


Before you do anything else check to make sure the blades are engaged on thier seat ( the star) and the blade bolts are tight.
If you have an electric PTO this does not apply to you.
After confirming that your blades are tight check the operation of the PTO cable and the pivot bracket by lowering the deck all the way. Laying on the ground on the discharge side of the mower you will be able to look at the components and see and touch whats not moving freely as you engage and disengage the PTO lever. Look for a stiff PTO cable, stiff pivot bracket, missing return spring, broken spindle brackets and broken deck bracket welds.
Of course you should never work on any mechanical device while it is running.

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.

Grinding when Engaing PTO for the tiller-Troy Built Horse 8hp


It's likely that your clutch needs adjustment. To adjust, you just need to loosen the two screws on the plate and slide it a bit so the clutch better engages the rear dog clutch. Have you ever taken the tiller portion off the transmission to grease the clutch? If not, before adjusting it you might want to do that. It could be that the clutch isn't sliding back far enough to engage the rear end and a little grease is all it needs. This service requirement is explained in the owners manual for the tiller. One last point, the tiller must be in neutral when engaging the pto clutch. From your note, it sounded like you were engaging the clutch with the forward/reverse lever in the forward position. The lever must be in neutral when engaging the pto clutch.
