There's a fuse in the fuse box for pto circuit. 5a according to my book, I'm too idle to step outside and have a look.
You've got the basic information, not much more I can help you with, I'm just a muppet.
I have a problem with my 8340's pto. Yesterday while on the diet feeder the pto just stopped turning. When it was knocked off and then reengaged you'd hear a slight pull on the engine but nothing happening after that. We've pulled off that round plate to look inside and when you start the tractor oil is pouring out of the pto solenoid area. It looks like it's spraying out around the pto brake actuator but it's hard to tell there's so much coming out. As soon as you engage the pto that oil pretty much stops flowing and only a bare trickle comes out. The tractor was on an agitator a few days ago and was ran flat out for most of a day fully loaded with no problem at all.Could be faulty pto switch or loose wiring. Check the wires on the alternator are tight and making good connection and is it actually charging good. Belt tight? Also pto control relay in fuse box may need swapped with a known good one. The insulation on the wires going to the pto control valve is known to break down.Can be got at through the round plate on the left side in front of the left trumpet housing.Behind the lower fuel tank(if you have one). Had this on my 8240--the wires were completely bare,internally from the rubber grommet to the valve.
We just been into back end on our 8240 and done the PTO plates and seals, parts came to £100 so can’t grumble really. Plates were ok but at some point in the past it musta got hot as seals were all like vinylI have a problem with my 8340's pto. Yesterday while on the diet feeder the pto just stopped turning.

For now I'm wondering if all that oil running out of the pto area is normal when the pto is off or has it blown out an o-ring or something?.
Is the pto accessible from the top or had you to split the tractor?.We just been into back end on our 8240 and done the PTO plates and seals, parts came to £100 so can’t grumble really. Plates were ok but at some point in the past it musta got hot as seals were all like vinyl
PTO had stopped working together but is fine now.
Chatting to a mechanic this morning who would have worked extensively on those tractors in the day and he said it's damn near 50/50 whether you split it at the transmission or lift off the lift cover. He advised me if we've a good way of working that splitting would be easier. I've adjusted the aluminium collar that carries the oil to the pack as it was quiet slack and had moved back a bit. The pto seems to be ok now but I'll know more this morning when it goes onto the agitator again. Here's hoping. I've enough on without ripping into that as well.You need to raise the back of the cab a couple of inches,minding the windscreen as you lift,and then lift the hyd lid off the top. Also,the top link bracket has to come off,then a plate,a cluster gear and a shaft that goes through the pto pack.
