Question about Ariens 34 In. Zoom Series Riding Mower

1 Answer

PTO does not engage

I replaced the PTO belt which broke after I tried running mower on lowest deck setting, "1", as I had just purchased the mower used and was trying it out. I am assuming I have it on right, as it goes from the engine pully to the clutch pulley, and has a tensioner pully pushing in from the side. Problem is the PTO still won't engage when I pull the red knob, so I suspect the clutch is out or there is a short/ bad connection. Is there any way I can check the clutch without taking it off and if not, how do I take it off and check or replace? Or is there another possiblity as to what the problem is? Also, are you aware of any problem with the clutches on Ariens going out often? Thanks, George

    I fixed it. Apparently when the belt broke it pulled the wiring out of the clutch. The 6 inch section of wiring harness was gone but I had enough wire from the switch to reach the clutch and it works fine now.

If your belt was tight when you finished installing it and all the pulleys that it went around are free turning by hand and lining up reasonably well you should be ok.
to the clutch
are you good with a volt meter 12volts dc?

Find your connector close to the clutch
unhook it from the clutch
take your volt meter and engage your red knob (Have the key on and parking brake applied)check your voltage to the connector
Do you have 12volts dc?if so your clutch should work if not you need to trace the wire back to the red knob
check all of your fuses check all of your safety switches.

Or have a 12 volt source (a battery )and hook it briefly to the connector you found directly to the clutch connector pos. and neg. from your battery you should hear an audible CLICK if so your clutch is good if not you are losing 12 volts back toward the red knob
this is the best way to check the clutch while it is still on the machine.
if its the bad clutch get your wallet out they are expensive.
to remove it unlosen center bolt on the crankshaft
remove or move belt guards out of the way and whole assembly should slide right off, note any shims and spacers that may come down with it and their locations
put back the same way it came off and tighten center bolt to 55 ft.lbs.
goodluck

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.

PTO turns without mower shaft inserted. Mower blades turn when rotating shaft by hand. Slide shaft back into PTO and nothing is turning. Belts on mower deck look ok.


Sounds like your magnetic clutch is not fully engaged or slipping and cannot handle the load of the mower deck..try this...Using a good pair of snug fitting gloves..with the engine in its lowest idle position and the shaft out of the clutch turn on the clutch..now carefully see if you can manually stall ( make the clutch slip) if it does sip or stall it needs replaced.just be careful....good luck..

Why does my Craftsman Garden Tractor # 917276022 that runs but when I engage the pto it dies immediately?


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

Something is jammed under the deck. If the engine runs good until you engage PTO, the problem is in the deck. With engine off, disconnect belt for deck from PTO, then remove deck and flip it over. With belt off try to spin blade. They should spin freely. If not, you have a bad bearing which are fairly simple to replace, just a few bolts. FYI, draw a diagram or take a picture of belt routing before removal, this will be good to refer to for installation of belt when your done. Hope this helps.

I have a Sears Garden Tractor with a 48" mower deck. By working in long, thick grass I broke the mower belt -- not the one that transmits power from the engine, but the belt that sits in a pulley on...


I believe that tensioner pully has to be loosend up and moved.
Here are the instructions for this.
  • Place the deck in the lowest position using the hydraulic piston (if applicable) or the manual cutting-height adjuster.

  • 2

    Remove the deck-to-PTO belt from the PTO by releasing tension on the idler-arm pulley. This is a spring-loaded handle that turns in only one direction by hand and relieves the tension on the belt. Slip the deck-to-PTO belt off the PTO pulley after the tension is relieved.

  • 3

    Remove the deck from underneath the mower or tractor.

  • 4

    Locate any belt stops and loosen them with the ratchet wrench and proper socket. Belt stops are located on the deck and are the small metal brackets that guide and secure the belt to the pulleys so it will not jump off when under heavy use, or stretch from normal wear.

  • 5

    Remove any pulley covers by removing the retaining screws using the ratchet wrench and a socket.

  • 6

    Loosen the idler-pulley retaining bolt (located on the underside of the mower deck) to replace the deck-to-PTO belt. Removing the bolt is not necessary. Loosen the pulley enough to wiggle the belt free from the pulley and remove and replace the belt.

  • 7

    Remove any arbor covers (if applicable) that conceal the arbor pulleys by removing the retaining screws with the ratchet wrench and a socket to replace the mower arbor belt.

  • 8

    Locate the tensioner pulley on the mower arbor belt to replace it. Loosen the tensioner pulley bolt enough to slide it and release tension from the belt. Remove the belt from the arbor pulleys and replace it.

  • 9

    Slide the tensioner pulley back leaving about 1/2-inch of play in the belt and tighten the bolt. Reverse the procedure to put the rest of the mower deck back together and reinstall on the mower or tractor.

    Blades will not engage, belt not broke but is very old, do I need new one?


    Check if the belt is loose. With the engine off, try to pull the mower deck belt around by hand. If you can pull it easily, and the blades don't turn, then replace the belt. If it's hard to pull, and you can see the blades try to turn as you pull it, then your problem probably isn't the belt, but the PTO clutch or mower engage switch.

    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.
