Ltx1046vt when I pull the PTO knob to engage blades it sometimes works and sometimes not. Sometimes if I switch it back to the reverse mode it will start the blades. If I need a new switch is it a hard fix?

Belt may have come off. Check the wire from the clutch and from the switch, you may have had hungry rodents during off season storage.

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.

Sounds more like a PTO clutch failure, rather than the switch. The clutch is mounted on the engine shaft, between the hydrostatic drive pulley (nearest the chassis) and the mower deck belt pulley (farther from the chassis).
Since it's an expensive part, make sure the problem isn't in the switch or wiring first. You could do that by probing the wires to the PTO clutch with an automotive test light - they are inexpensive and handy. Clip the ground wire of the test light to the chassis, and probe the hot wire to the clutch (it's the one that doesn't connect to ground) when the engine is running and the PTO switch is engaged. Obviously a helper has to be in the seat, and you should be careful doing this. If the light glows brightly, and the clutch doesn't engage, you definitely have a bad clutch. Good luck! Please rate my answer if helpful, thanks.

Hi,
I would be looking at the ignition switch....but before replacing it I would be looking for a friend with an electrical meter and checking the wiring for power coming out of the switch to the cluthch, this way you can narrow it down positively before buying parts.

The electric PTO clutch on a Cub Cadet L1045 allows the mower blades to engage. The electric clutch is located directly under the engine and is bolted onto the crankshaft. When the PTO switch is placed in the on position, an electrical current is sent to the PTO clutch; engaging a brake which then allows the blades to turn. When the PTO switch is in the on position and the blades will not turn, the electric PTO clutch may need replacing. Check the 2 wire conection under the frame near the pto clutch, motor off of course. Make them tight.
------- First start by turning ign on,then switch on the pto switch to on. you should hear a click in the clutch. If not use a twelve volt test light,hook aligator end to a good ground and the needle end,touch to the pto switch harness to see if you have power to the pto switch.If you don"t, you have to go checkfurther to your power source,(battery) if you do have power there check to see if you have power at the plugin at the end of your wire harness, just at the beginning of where your cluch connects up. You can test you clutch by conneting a test wire from positive on your battery to one of the terminals on your clutch and the other terminal to ground . It will engage if it is good .--------- But if not then by pass the pto and see if the clutch gets engaged.If it gets then replace the pto switch, but if its not engaging by bypassing the PTO switch then problem is with clutch, it has to be replaced. ------------ This will help.Thanks.Helpmech.
