Tiller Tractor HP vs implement rating

   / Tractor HP vs implement rating #21  
. . . On the slip clutch thing, it is my understanding that manufacturers want them tested and recalibrated on an annual basis to make sure they slip when they are supposed to. I have never done that and don't know anyone that has for what it's worth. Just my two cents.

I do it at the beginning of the season when the cutter has been sitting all fall and winter. I figure it's a 20 minute job that helps protect my tractor and/or cutter against friction discs that are "frozen" together.

How do you go about doing this? Is it just loosen the bolts to make sure things spin and then re-torque?

First of all, I had to remove the cheap plastic PTO shield to do it. Having the shield in place makes it almost impossible to get to the bolts.

Yes, I loosen the bolts/nuts that hold the springs that force the friction discs together.

Then I make a mark straight across the slip clutch mechanism including the flanges and friction discs.

Then I engage the PTO for a second or so. Then turn it off and check the mark to make sure it is not still aligned.

If the mark is broken, then I tighten the bolts/nuts up until the springs are flattened out, and then back them off 2 turns.

After I do this, I usually make another mark straight across. After I hit something that should have forced the slip clutch to slip, I'll check it to make sure it actually did slip.

Thanks for the step by step, this'll come in handy.
