If the PTO clutch is not receiving power, the clutch solenoid is defective, or the clutch itself is worn out, the blades will not engage. Since a PTO clutch is not repairable, you will need to replace a broken or worn out clutch with a new one.
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.
The PTO switch is a critical safety device developed to prevent unintentional blade actuation of lawn equipment. This switch is part of a series of controls that comprise a mower`s safety interlock system, requiring riders to use proper procedure when operating machinery.
A high lift blade delivers maximum airflow for the best cut. But it does need a higher horsepower mower to perform, therefore using more gas. This is the ideal choice when you are bagging, since the higher lift force will send the clippings out of the deck.
High-lift mower blades mean blades that are designed to lift the grass after being cut. This kind of blade has curved edges, which helps create more airflow that lifts the grass after it has been cut and sends it to the bag. This applies if a bagger mower or a side discharge mower is being used.
If/when the PTO exceeds the preselected RPM setting, the EOC will de-energize the solenoid valve, disengaging the PTO.

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…
While mowing , I loose RPM and it quits cutting, then engages blades and rpm goes up and everything is fine. I just changed the belt. Could that have any bearing
I would look for a loose wire connection first

Arien 34- Blades won't engage – Ariens 34 In. Zoom Series Riding Mower
This mower has an electric PTO on it. I had a Scag and the electric PTO clutch went out on it. Not the cheapest things to change but easy to do yourself with some basic tools. Also, before running out and getting a new one, check the wires to it and to the engage/disengage switch. You may have a bad connection.
When I engage the PTO, the blades don’t egage.
The first thing we need to to do is verify that there is adequate /(power 12 vdc) going to the electric clutch, you can do this by unplugging the clutch and check both wires 1 should have 12 volts and the other wire shoud read infinity to ground if this checks out replace the clutch, if you dont have 12vdc to the wire replace the relay
