Very frustrated with my walk behind

I have an exmark Viking 48" hydrostatic 2013 with 80 hrs on it and am having a lot of problems with the cut. My mower is leaving a lot of areas of uncut grass. I have tried all different types of blades from mulching to medium lift to high lift with all having the same problem. I have cut in wet conditions and dry and all with the same result. I can go from speeds of 1 to 6. When I go at 2 it cuts great. However i usually go at 4 which is not too fast, and I have seen a lot of uncut areas, requiring me to double cut. Is it this particular model that is having these types of problems or do I need to upgrade to the next model of walk behinds. Please help

Did it cut fine at one time then change over time?

No. It has pretty much always been cutting this way. I have been noticing it for a while now and have done everything that I can do. Like I said I have asked a lot of people and tried lots of different things with the same result. I am starting to feel as though it is a defect in the model

Might be cutting to tall. Blades don't have enough lift to pull the longer grass. Also check your deck belt tension. Blade sharpness. And could try different blades

There has been lots of problems with Exmark's lately where there is uncut grass. Usually the uncut grass is located there the blades meet. People said replacing the blades may help, but some of the blades you tried aren't helping. See if you can try every type of blade on your mower and go from there.

Only thing that I have found that works is heeling the deck just a 1/4 inch

honestly, I have tried every type of blade. My mower is missing where the blades meet. What do you think of the turf tracer, either series.

some of my customers ask for me to cut all different heights and all of them still had the same problem and a lot of uncut/ missed grass

Do you have the deck level or lower in the front?

yes I have tried both. I have heard that having the front of the deck lower might help but it hasn't. I have went all through the manual and I now have it level and still have the problem

Try sitting the back a 1/4 inch lower then the front

I use a Scag 36" and an older better outdoor product 36" walk behind on a regular basis. both are set at 4" s. I don't trust the measuring mechanism so I use a tape measure off the shop floor. you might try setting it level and adjusting the height using a tape measure. I'm not there so I don't know exactly what's going on but that method might be worth a shot.

Vikings are fixed deck mowers, correct? If so, do they use blade spacers? Again, if so, consider removing some spacers to get the blades further under the deck or vice versa add a spacer or two to get the blades closer to the bottom of the deck. Have you tried cutting 1/2" lower?

If all of the suggestions you have received fail to work it is time for the dealer to help you out. A 2013 should still be under warranty.

I put my blades right down to the bottom edge of the deck.

Reason for suggesting raising them in the deck a bit was to get better vacuum and lift for a cleaner cut. Not sure how high the op is cutting or what types of grasses.

Have you checked your engine speed? If it is running too slow, that may contribute to the problem. If my memory is still any good, I think the Viking mowers were set to run at 3500 RPM's.
