SOURCE: What could cause a pto clutch to seize and a idler

First thing is dry bearings. Over time, the ball or roller bearings in both units can get dried of lubricant. The only solutions are to lube them before they are damaged significantly {beyond use} or replace them. If this is not an electric PTO clutch, then it is likely the linkage that operates the PTO clutch is in need of adjustment and/or lubrication. Most use an idler pulley on a V-belt as the 'clutching' mechanism. If the linkage is binding, or the idler pulley out of adjustment, it won't work well.

I have a 52" Husqvarna LGT 2654 riding lawn mower and when I engage the blades, the belt does not turn the pulley system. What could be causing this, the pulley idlers, or the belt?


depending on the age of the machine, there could be several possibilities
1-- belts are not tight enough--- belt tension system is not correct, wrong length belts
2--bearings for the shafts for the blades are rusted up and seized - preventing the blades from moving--- switch the machine off , disengage the belt drive and see if you can turn the blades by hand
3--- if you have an electric pto system to drive the belts to the blades then that system is not getting full power to engage the PTO or the clutch is not working--worn facings
take it to a service dealer and have a proper diagnosis done

The power take off starts slipping and cuts off after it runs for a couple hours, what is the solutions to my problem


If you are talking about an electric PTO system, then there are two possible causes. The first is voltage drop. If your alternator is not charging the battery correctly, the available power to operate the PTO Clutch will drop below critical level. If you have to keep putting the battery on charge, this is almost certainly the cause.

The second possibility is mechanical failure of the PTO clutch. One of the most common clutch failures causes them to overheat and when the temperature increases, so does the electrical resistance.

Try this test:
Park the machine on a flat, level surface, switch the engine off,lock the brakes, remove the spark plug lead then remove the cutter belt from the engine pulley.
Now try to turn the PTO pulley on the engine. It should be firm to turn and you may hear/feel a slight grinding (this is normal). Next, turn the ignition switch to the 'run' position (NOT the start position), then turn the PTO switch to the ON position. Reach back under the machine and try to turn the PTO pulley again. This time, it should feel much heavier to turn because it's now connected to the engine shaft. It should turn smoothly for about 3/4 of a turn either way. Most importantly, you should no longer hear/feel any grinding. If you can still feel grinding, it means the PTO clutch has had a mechanical failure. In some cases, the fault can be rectified, however it is not generally recommended as a D.I.Y task.

How to i change the drive train belt on my cub cadet z force 50


  1. First park your mower on level ground and apply the parking brake.
  2. Remove the deck drive belt from the PTO clutch.
  3. Remove the electric PTO clutch. This is done by disconnecting the electrical wires first. Then removing the center bolt using an impact wrench. A pull bar can used but you must prevent the engine from turning by blocking the flywheel.
  4. Remove the tension on the drive belt idler.
  5. Remove the drive belt from around the pulleys. Be careful as the engine may try fall off depending on if it isn't seized on yet.
  6. Installation is the reverse of the above instructions.
  7. After install the PTO clutch tighten the center bolt to 55 ft lbs using a torque wrench (not your impact wrench) with the flywheel blocked from moving.

Depending on your engine.. Briggs and Stratton or Kohler there are 2 different seat switches that are used to power the PTO clutch. The seat switch can cause the PTO clutch to disengage anytime there is not at least 70 lbs in the seat.

The PTO drive wiring has a 30 amp fuse in it. If by chance a stick went through the belt and tore off the wires at the PTO clutch (Common failure) even after you repair the broken wire you still need to replace the fuse.

Check the PTO clearance gap. It should be 0.012 dis-engaged. Any other value and the clutch will not work correctly. Adjust the clutch if necessary.

There is a 2 pin Pigtail just off of the PTO Clutch that you need to check for voltage at the connector. Probe the back of the wires if you can and your looking for 12V DC under the following conditions.

BRAKE ON or tied down
KEY ON
SEAT (Briggs and Stratton engine only) Someone needs to be sitting on the seat.

Then Pull the PTO Switch out. You should hear the PTO Clutch CLICK. If you hear the click there is no need to check voltage. The PTO switch is a multi function switch and it is quite possible the PTO switch failed. I doubt that the PTO Clutch has failed as they normally give you some kind of noisy indication that they are failing and don't fail straight away.

So.. In short
Check PTO Switch (Red wires) to usually red or brown thru the switch
Check 30 amp fuse
Check PTO clutch wires near PTO clutch (They get torn from something traveling through the pulley)
Check PTO clutch clearance at 0.012
Check Brake switch for an audible click as you depress it some distance No click.. possible bad switch
Listen for Seat switch Click as you slowly add weight to the seat. No Click or any click and it can still be suspect due to the Briggs and Stratton installed engine ones have more than one function.. Ignition and PTO clutch power.

The actual wiring diagram is on page 35 of the owners manal that can be found here:
http://www.managemylife.com/mmh/owner_manuals/27245/CRAFTSMAN-Lawn,-Tractor-L9910386?brand_name_search=917273023

Lastly... check each of the mower deck blade bearings. A seized bearing can cause PTO problems.

Hopefully you have enough information to solve the mystery. If not just respond here and I will help you.

Thanks for choosing FixYa.

How do i get the upper pulley above the pto clutch


I've yet to remove these in one piece...even when I smeared anti-seize all over it. You can try a 3 jaw puller, but you'll most likely end up just bending the pulley. The pulleys are about 25 dollars locally in my area. Honestly, i just air chisel them off, and buy new every time i change drive belts.

My PTO will not engage without grinding but works great once engaged, Model is only shown on the engine as C10 with production code of 5F5B and serial A281771


when u engage u have to push in clutch and wait for spinning gears to stop the engage pto and let out clutch, excessive spinning of gears can be caused by low transmission grease also causing grinding
