flat out cleaner cut and since the new deck is much deeper you can mow faster to achieve a better cut. productivity and quality is the difference.
but it comes withthe price of less vaccum for double cutting( you know how a deck sucks op clumps of wet grass) . that and the deck is so heavy like i said about the wheels digging into the ground when wet, but it is only extreme ditches and berms when turning, not regular forward motion with dips etc. you can work around it though, jut did not have to on the older decks.
all is fair in love and grass!
Man, it smells like sheet, do you smell that!!
