Garvo, was wondering how you liked the hydraulic hayhead on the 3970.  Have a gear getting worn on ours, and thinking it would be nice to convert it over like yours, since it is a pain to connect the chain to drive off of the chopper anyways.  By chance do you know how many teeth are on the sprocket or have any closer pics.  Thanks for any help.
