Pto Clutch For Stx38 And Stx46 Lawn Mowers
Experienced gardeners share their insights in answering this question :
Had a similar problem. The engine mount bolt that grounded the PTO black ground wire was loose- causing the pto to work erratically. To see this bolt (13mm i think) you will have to lie on your back and look under the machine. It is above the front steering arm of the right tire. If the wire is dangling you will need a new bolt.

How to Identify and Fix Common Gardening Problems ?

If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.
Powershift PTO engagement problems could be from blocked hoses or fittings, bad connections or ground or the solenoid. Mechanical PTO engagement problems could originate from low air pressure, improper cable installation or back lash too tight.
This operation is crucial to the overall functioning of riding mowers, and thus PTO clutch repair may need to be immediately performed on riding mower models that have a failed clutch. Fortunately, you can fix your clutch irrespective of your experience with PTO clutch installation.
A clutch that won`t engage at all means there is serious damage somewhere. Check for a bent linkage, a seized slave cylinder, or a seized throw-out bearing. Beyond those, check for binding in the linkage, a corroded cable, or a failed friction plate.
Pump trouble is usually characterized by increased noise, increased heat, erratic operation of cylinders, difficulty or inability to develop full output, decreased speed of cylinders or hydraulic motors, or failure of the system to work at all.
For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. This locks the PTO output gear to the output shaft and allows work to be done. When the power shift PTO is disengaged, the solenoid de-energizes.
Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
PTO clutches generally overheat because of improper lubrication/greasing (both too much and too little can cause problems), excessive sideload, or a new installation. Operators are advised to reduce sideload and inspect grease levels first.

I have a Craftsman FS5500 48″ lawn mower. The PTO makes a noise (squeak) for a second when I pull up on the red blade engage knob. The blades do not engage. PTO does not turn. When I push the red button down to disengage there is a brief squeak from the PTO.
It worked well the past month then a little problem 2 weeks ago. It seemed to disengage after mowing a while. Then after sitting for 15 minutes the blades would engage. I used it earlier this week and the PTO won’t turn at all.
Just purchased from the last and original owner a month ago. He said the oil would need to be changed this summer. Could that be part of the problem? Engine runs great!
Also, I need an owners manual, not able to find from the previous owner.
Hi,The problem is probably in the button that you pull and push to engaged and disengage the PTO… If you wiggle the button or try to pull it slowly, you may find a spot where it will work. But the button has gone bad and will need to be replaced.If you are comfortable with wiring, you could jumper the wires and getting it working, but it would be a very temporary and possibly dangerous fix…
Cub cadet lt 1050 electric pto want engage??????????
Make shure pig tail is hooked right
I have a electric pto that come off a cub cadet and the part number of the pto is 5219-25 its a warner. My question is one of the wires have pulled loose in side the magnet are there any way to remove the magnet or take the pto apart? the wire is broke off inside the magnet. Thank you
Most likely you cannot repair this as the wire ususally breaks off inside. If you remove the assembly, you can see where the wires go into the potted coil. If there is no excess wire to reconnect to then your only choice is to replace.
Where is the fuse located on a LT1554 cub cadet
Check the connector and wires at the pto clutch. Sometime the movement will create a cut in the wiring you may be able to see. If so if the wire touches ground it will blow the fuse and if the wires touch each other it will short.
if the short is not there then the clutch is bad?BMW PARTS
