Hello, i have a wd45 with a belly mower on it. I mowed with it the other day and the pto turned on and off just fine. Today i went to mow a bit and the pto wont turn on. Is there any linkage that may be goofed up or a shaft that aint seated right or something? Im not too familiar with allis tractors so i didnt know if there is anything common about this or not? Any help would be greatly appreciated! Thankyou
 
AS Ted said there is a simple shear bolt that may have gone bad or you may have broken shift linkage like I have run into but the most common is the shear bolt
 
If the shear bolt is sheared, do not replace it with a common bolt. Get the correct shoulder bolt from a dealer....unless you want to wallow the shaft and sleeve. Another option is an internal problem, like broken drive gears....but I"d expect that to get noisy. Also check the bolt holding the lever to the shift shaft. It is a sliding gear setup, so the internal shifter could be broken. It is just a lever, not a yoke. But KISS- check the shear bolt first- that is what they are there for. Personally, I"ve never broken one, even on forage choppers and blowers, but some cutters can be hard on them, because the load changes so often, especially if they are not kept tight. Pulsing loads are harder than a steady load like a forage chopper.
 

I hope you have been told (long ago) that you ALWAYS put the transmission in gear, BEFORE you try to engage the PTO..
Otherwise, the transmission may be coasting (still spinning) and the PTO is very easy to Jamb and grind the gears..
Those WD-45 PTO gears are fragile enough, without causing them any more stresses..!!!

If you do not find anything else..draining the transmission would be next, followed by removing the PTO Gearbox..
IF any gears are broken, the parts should be easy to find..
Many times, one of the "Ears" on the top of the PTO gearbox fractures and that allows the gears to be destroyed..
I havent heard of any WD's breaking this part..even though it is not as strong as the Beefed up WD-45 gearbox..
Anyway..I hope it is only the front shear bolt..!
I like to drill through both ends of that bolt and Safety-wire it, so it will not have any chance of working out (Broken) and possibly breaking the transmission housing or PTO gearbox housing.

Hello, thankyou for all your help everybody with figuring out the pto on my wd45. Sure enough it was just a sheer bolt. Thankyou for all of your help and take care!
 
Any old gear driven PTO tractors I run a mower or baler on, I use an Over Run Coupler to keep from sheering bolts.
