3.8 to 4.0 MPH {No-till ground}

Watch monitor and it goes downhill, above those speeds; BUT I'm still on 38" rows (in Corn), so my plant spacing is closer, and I need to be more particular on spacing = less room for error. 


Note: I've watch some you-tube videos, and even some guys with 24 row planters and fully loaded monitors and fertilizer on their planters (pulling those big air carts), were only planting at 3.8 MPH, also.
