Vertical TMR. Whole bales vs grinding hay?

The vertical mixer is immune to pluging, but is painfully slow to grind hay unless the tractor running it is at speed, especially if the load is small. Monomixers are faster at grinding hay, but can plug in certain conditions, mainly in grass hay. They will also grind just fine at lower pto speeds, just more slowly.
