2305 pto not engaging.

I was mowing and I shut my mid mount mower pto off and it kept spinning. I pulled it back out and pushed it back in and the blades stopped turning. Then I pulled it back out and now the blades won't turn. Does this sound like a solenoid of some sort?

Those push pull PTO switches are pretty reliable, but the 2305 is also 12 to 17 years old. Check the PTO switch and and make sure the connection on the back of the switch are clean and securely on the switch.

The tractor isn't running hot, is it? There is an over ride circuit to prevent the PTO from engaging if the engine temp is over 225F or so (would have to look at the actual TSM for the shut off amount).

It could be the solenoid, it could be a safety switch, you really need to go through the diagnosis procedure for the pieces and parts involved. There are relays which control several functions and most are all the same relay, used in different ways.

This is one of those times where the Technical Service Manual is very valuable.

Yikes, I sure hope its not the PTO solenoid, which is on the rear case as that is $430+. Here is the parts schematic

Here is a look at the relays and they appear to be together.

They also show the entire PTO "Cutout Harness" in the following screen shot.

Here is the actual link to the page in the parts book.

So I took my deck off and the mid pto just spins freely when the tractor is off. I'm guessing that is bad.

Or the lever which selects the PTO position between Mid and Rear is knocked out of position..............and just needs to be put back in its correct position.............also check the linkage under the tractor where the lever connects to the rear housing.......Does the rear PTO function as it should?
OK figured one thing figured is I'm an idiot. Thanks for getting back so quickly. I feel a little better now. I thought I had major issues for a second. I forgot I moved the selector to rear last night to see if the rear pto came on. It didn't. I tested the switch it had continuity on the outer poles when off and on the middle and one outer when on. That seems good. I'm having troubles finding the relays. Whereabouts could I find those?

Not sure as I haven't owned or worked on a 2305, but since there are 4 relays shown together in the harness and they have a bracket with the bolt, I would focus on the side of the dash under the steering wheel area, where the main harness is located.

Here is what the relay's typically look like in an acual photo. You can get most of them at your local auto parts store as long as the plugs are the same and they have the same rating. That information is on the relay itself. Also, you can switch the relays as all 4 are the same. It appears to me the PTO relay is the 2nd from the right based upon the drawing but I don't know that is 100% accurate.

Look around the under dash area for the 4 of these together.


or without the mounting tab on top...They are about 1" square or so. If you see 4 square devices together side by side in the electrical harness, its most likely what you are looking for. Also, trace the wire from the switch and it should lead to the relay block.............
So I've got 30 volts back to the pto solenoid when the pto is on and no volts when off. That is at the harness the pto solenoid plugs into. My solenoid also has continuity.
So the coil pack is getting power to it when the pto is on. The coil pack has continuity. Is there a way to test for mechanical failure of the solenoid?
Did you ever get your tractor fixed? It seems that I'm in the same boat.

Mine ended up being the pto solenoid. The coil pack was still good but the solenoid had mechanically failed. When I took the solenoid out and pushed on it it didn't spring back like it should. Put a new solenoid in and I was back in business.

On the attached pics I pointing to the part that should spring if the solenoid is working properly mine had not springing to it. Before you take the valve out make sure you are getting power to the coil pack just to rule that out.
