How common are electric PTO clutches now?
All my experience until I bought my newest tractor was with Massey 135's. As most know, it has a 2-stage clutch. Engage the PTO lever and as you come off the clutch pedal it starts the PTO and the next stage it starts the tractor moving. And it's a cushioned start to the PTO because of the springs on the clutch.
On my newer tractor it has an electric PTO clutch that's engaged by a switch on the clutch pedal. If I'm anywhere above the lowest engine speed when I come off the clutch then, Bam! Replace the shear pin. Instant PTO engagement and no cushion of any kind. I've never replaced a shear bolt using the Massey, even starting at full engine speed.
Is this common now? Or should there be some sort of cushioning device that just isn't working on my tractor? Even at idle I can't see an instant SLAM start being good for any PTO driven equipment.
