Blades mowing problem

[benoitbuyse@hotmail.com]

Hellow everybody,


I have a walker mower MD diesel model from 2008,

when i cut, it leaves a stripe uncut in the middle, it seems they are not overlapping anymore but i can not believe that..

sorry for my english!(Belgian)


Someone have an idea?

This thread gives you some ideas: http://www.lawnmowerforum.com/scag-forum/16576-leaving-grass-uncut.html

But these are some common reasons:

• The blade tips are worn.
• Your overlapping may be insufficient: The tires push down grass during each pass. If you line up your tires with tire marks from the previous pass, the grass does not get a chance to stand back up during either pass. Overlap more than the width of your tires on subsequent passes. This will allow the blades to draw up the trampled grass from each previous pass and should produce a nicer looking cut.
• I don't know if this applies to zero-turns: Right hand turns: Twin-blade mower decks are designed with the discharge on the right side. The left blade is positioned slightly forward and in front of the right blade. During left turns this cutting overlap is maintained. This provides cutting overlap when traveling in a straight line. The tractor operator should therefore make mostly left-hand turns when cutting grass.
• Improper cutting deck adjustment: This can produce a vacuum imbalance that, under certain circumstances, causes airflow to push outwards from the front of the cutting deck. Consult your tractor Operator's Manual for specific Deck Leveling and Deck Engagement adjustments pertaining to your specific model tractor.

42" blades on a 48" deck?
Blade on wrong side,
blade upside down ( don't laugh, seen it many times!)

What service or repair was done while it mowed OK, then changed?

Rear discharge or side?

Did it always do this?

Did you hit anything or let a friend use the mower?

On the rear discharge they are counter rotating blades. The have to be timed in the correct position. Te blades also have to be put on the correct way for them to work. http://www.walkermowers.com/manuals/mowers/model-md-manuals/7000-6_pub.pdf page 41 for a diagram of how it goes.
