That's how they are..i like the ventrac setup better too..after 23 yrs on 3 different steiner decks ,I got a ventrac deck and wished I'd swapped them all out.I feel the steiner 60" MD460 has a slightly better cut quality than anything ventrac makes, it's not a big enough difference to make up for the rest of the things that make the ventrac deck better, and it's lighter..the steiner 60 and 72s are too heavy, with too small and thin front castor wheels, this combined with the rear roller setup and it digs in when mowing soft ground, even with weight transfer, where the ventrac glides over without sinking or tearing. The steiner decks i preffer in tall thick grass they have a very tall discharge chute, and with the deflector up or off, it throws grass 2-3 passes easily and disperses great and evenly, again not enough to make me want to live with them over the ventracs superior overall decks.
