Dual blade mower leaves uncut strips between blades.

If you were able to jump start mower then the problem lies with the battery connections or battery itself

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.

I have a 2014 HUSQVARNA RZ5424 that I just changed the blades on for the first time now 2017. I got new gator blades because of all the good reviews on them. They are about as good as a screen door on a submarine at 300 feet deep. There the same length as the original blades but leaves two rows of uncut grass about a inch wide regardless of how you try to cut it. Only 240 hours on mower, deck clean ,spindles kept greased . Went back to new Husquvarna blades like the ones made for it. PROBLEM SOLVED. HAPPY HAPPY HAPPY. REL.

try sharpening the blades on the mower. dull blades can sometimes cause a strip of uncut grass

Sharpen the blades,very sharp,and lift the deck one notch from where you normally cut.Some times the blades will get dinged,or the ends of the blades will dull.

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.

i have the same problem I wish I knew what was doing it I also changed the shaft and still. Could the blade be upside down?

You may be running too fast on ground speed for the mower deck to cut completely. It may be time for some new blades. The blades may be worn down to where they are shorter than when they were first put on.

measure blades on a level surface.place each blade side to side and see if their is a difference,all measurements should be the same,if not you have a bent deck or a spindle that is bent.
