If the PTO gear does not fit snug on the shaft, this will lead to easier shearing off of the key. Unfortunately, the only way to correct a loose gear on a shaft is to replace the worn parts. You could try using a softer shear bolt to see if that will take some of the “jar” off the PTO when the shear bolt breaks. It’s tempting to take them to a machine shop and have the key cut out oversize. That might keep it from shearing off, but may cause damage to something else further into the drive line.

Maybe someone else here has some ideas…
