SOURCE: 2007 Husqvarna Riding mower blade will not engage

Sounds like you electric blade clutch is bad. I just had the same thing happen to my exmark mower. I was cutting grass and the engine just shut down. It would not crank over. Checked the fuses and replaced one blown fuse. The engine wanted to crank over but it was locked up. I looked the engine over and seen that the bearing in the electric clutch seized up causing the clutch to melt.

SOURCE: blows fuse for blade clutch after 20 to 30

Most likely there is an internal short in the PTO clutch, but it could also be in the wiring, which is way cheaper to fix! So, with the engine off, get down on the ground, find the PTO clutch (it's between the two pulleys under the motor) and trace the wires that go to it. Look for a worn spot in the insulation anywhere, especially likely where the wires pass through the chassis or if they've touched a belt or other moving part. If you find a wiring problem, just splice in a new wire.
Ok, if you found nothing, then unplug the connector that connects the wires from the PTO. Start the engine, drive around, engage the PTO switch (of course, the blades won't spin). If the PTO fuse does not blow, you've proven the problem is in the PTO clutch and you must replace it ($150 or so, sorry!). If the fuse does blow, that's good news, you just have a short in the wiring or in the PTO switch itself. Disconnect the wires from the switch to differentiate those two possibilities. The PTO switch isn't too expensive either. Good luck! Please rate my solution if helpful.

SOURCE: When the blade engage knob

I started out on small engine so I'll try to answer this. Like most newer tractors, I'm sure it has an electric clutch that engages the drive belt for the mower deck. The clutch is under the engine on the end of the crank shaft, usually. It works like the a/c compressor clutch on a car. So a few easy things to check would be:
Is there anything jamming the blades or belt?
Is there anything jamming the clutch itself? (extra grass build up,etc)
If not, unplug the switch from the clutch harness & with a multi-meter set to read continuity or ohms, check the resistence to the clutch after the switch. If the meter "beeps" or goes high, the clutch is shorted & bad. Replace the blade clutch assembly.( not easy without the right tools) If it doesn't "beep" or reads near zero, the problem is the switch or a jam. Could be a chance that a wire shorted out in between the two as well. The seat switch can be eliminated because the engine runs. Try that.

My blade will not stay engaged to mow. how do I fix the problem?

When you say will not stay engaged you are saying that it comes on then cuts off ? If you turn on the PTO and it engages and the mower is not moving does the PTO stay engaged and for how long (if OK then need to check connections for PTO ) . If it is not engaging at all then we have to look at interlocks / safety switches . Give me some Details

Mower running but when blades are engaged they stop and start back up

More than likely the issue lies somewhere in the safety switch for the reverse. On most of those mowers when you back up the blades will disengage and then reengage one no longer backing up, it probably just needs adjusted, sounds as if it is out of adjustment and over sensitive. Hope this helps
