Mower blades won't turn when PTO Lever is engaged

First, is your PTO Manual (You Throw a Large Lever) or Electric (you push a button or pull a knob) If it is manual, check the cable that it is in position and not broken or stretched. If it is electric this is not as easy. First check for a fuse and relay. The power for the PTO switch is feed through the ignition switch so check connections at the ignition and pto switch. There are safety switches involved, mainly for reverse. This is usually a plunger switch and may be stuck. Most tractors have an override button or position on the ignition switch so try with these engaged. If it works the safety swich is your problem. Beyond these simple checks now you are traveling into the realm of electrical diagnostics. Check all connections between the PTO switch, and the ignition and the PTO clutch. Still nothing, you may have a bad clutch. These are expensive and you should have a tech check it before you run out and buy.

Husqvarna riding mower

Jim, I believe your tractor has an electronic knob for engagement (if I'm right in you having a matching post about a husqvarna with a knob for engagement. And it also has a PTO clutch off the motor. Having a little slack in the belt is not bad if it's not so much that it doesn't grab at at all. Does anything happen at all when you pull the switch? If nothing happens at all, the switch could be bad, the PTO clutch could need adjustment or be bad, OR you may simply have a very weak battery that isn't supplying enough current to engage the PTO properly under loads. Sometimes the batteries and charging units in riding mowers are very borderline in being able to handle the loads and a weak battery can cause unsuspected problems.

When engaging the blade for my Husqvarna riding mower, nothing happens. I recently had the mandrel assembly replaced for the left blade, and this is the first time I've tried to start it up.

It's possible the repair folks didn't properly reinstall the mower deck belt. Check that it's in place, and under good tension. If that's OK, look at the wires to the mower engagement switch (PTO switch) and make sure the connections are on tight. Then check the motor pulley where the PTO clutch is, making sure those wires still in place.

Check your mower deck spindles and belt. If belt is slipping at all the PTO will not engage.

Just stopped engaging , when you pull the PTO switch you get nothing

The belt may have broken or is jammed, you'll have to look underneath the mower, have somebody move the PTO lever back and forth and you watch to see what if happening

Craftsman 26hp Garden Tractor PTO not working

If you changed the belt make sure it did not interfere with the wire that runs from the pto clutch, sometimes that belt can rub on the wire and wear through it,also if you had the clutch off make sure you aligned the steel retainer bolt that sets in the alignment hole on the pto clutch,this keeps the clutch from spring when disengaged if you don't get that pin through the hole in clutch it can push on the clutch and bind it.Also it may be possible to plug that pto switch in backwards.Also if you jumped the fuse out it may now have burnt the switch or wiring somewhere.
