I have a mid-90's MTD riding mower with a 42" deck.
I've been getting uncut strips, and after closer examination
it's because the deck is only cutting about a 36" wide path.
It seems to be leaving about 3" uncut on both sides of the deck. I live in
Massachusetts, and the cutting height is about 2-3/8". I've changed the
belt and blades, but neither helps. The deck has been banged up a normal
amount. I've banged it back extremely close to it's original shape. The
deck is levelled properly. The hangers aren't bent. I cannot for the
life of me understand why it doesn't have a full 42" cut.
I run the engine at full throttle, and I drive at extremely slow speeds.
The blades are all the correct heights from the ground. Side-to-side the
blade tips measure 42".
Has anyone ever seen anything like this? Does nyone have any other ideas
that might cause this?
Do other mowers with 42" decks cut a full 42" path?
The MTD website indicates the tires press down on the grass and that one
should overlap cuts more than the width of the tires. However, that would
mean each pass would only cut about 30". Shouldn't a mower with a 42"
deck be able to overlap a couple of inches and cut at least a 40"
path????

Could it be that the air flow under the deck has been disrupted by
damage to the deck?
