Got the flywheel on and off and now the shear pin issue has gone away. Apparently it was masking an issue with the over riding clutch for the pickup (super sweep). I run this baler in "moderate" windrows and I move fairly slow (1 or 2 with a D17). If the windrows get a little heavy the over riding clutch starts to slip stopping the pickup. The 276 manual gives extremely little information about adjusting this clutch (in fact it primarily says to "adjust it"). Check the online manual for a 278 and it gave a few details on how to adjust - "tighten" the 8 bolts on the clutch.
How much "adjustment" do you get by tightening these bolts? I tighten them all about 1 and 1/2 turns the issue got better but in the rough ground I am in (waterways) the pickup stopped a couple times when the tines scraped across the ground.
