Why is my husqvarna zero turn leaving a strip of uncut grass on the left side of the deck

Are your blades sharp? Are they lined up so they do not leave grass in between them as they spin?
Is your cutting deck level or is one side higher than the other.
These are all things that could cause long grass to remain.
Some times a bent blade will do this also.
I even had a lawn mower come in and the blades were installed up side down. He wondered why it would not cut right.

What are the size of the streaks? and where in the 48 inch swath?

You should be using a up lift blade it will help by sucking up the grass to be cut. You should have an adjust on both sides of the blade deck . As for the strip check to see if you have a wheel behind the mower deck. If you do it might be the cause for mower leaving a strip uncut . Sears has been noted for putting wheels in the path of the blade area and smashing the grass down . That is also why I suggest to use an up draft blade it should **** the grass back up again so you can cut it.

Hi, this may sound obvious but make sure the new blade is the same type as the old one and make sure it is not fitted upside down. Spin the blades and make sure the tips are level with each other, this will tell you if the deck is straight where the blade spindles mount. Regards Phil.

Check the blades, I expect that you will find that they are wearing out.

On a two blade deck, such as yours, there is generally an overlap between the cutting coverage of the blades so that you do not leave a mohawk. This does not work well on turns however, and the sharper the turn, the more grass is left. Overcoming that issue brings you up to a 3 blade deck. If your mower is leaving a strip of uncut grass while cutting in a straight line, somehow you are running blades for a smaller deck, thus there is no overlap. The mandrels are offset, one slightly in front of the other so that the blades do not hit each other. I would measure under the deck and see how long a blade could be and still fit within the deck and not strike the other blade, then ask a parts store to sell you something longer than what you have now.

Your blades may be erroded on the edges? Or the center blade hub might be damaged or worn.

good time to inspect all the blades and spindles for wear or damage.

change the blade

a lot of problems here.try this.[grass buildup]. usually cause by damp grass or blades not going fast enough to throw into box.engine cutout is then caused by grass jamming blade[s]. backfire is usually too much choke or wrong petrol/air mixture.re bent grass.try cutting driving in reverse[if strip is wide cos of back tyre then blade is uneven.]
