I hope you guys can help with a little issue i am having...
Last summer i bought a 2005 LX280 in good condition. It cut fine and ran just as good. This mower has a 48" blade housing (3 blades). This summer i noticed that an uncut line was being left in my cut grass. This line is about an inch wide just inside the passenger tire. I figured it was time for new blades anyway, so i replaced the blades, still had the line. I also checked and put the correct air pressue in all tires...still didnt help.
Next, I went to adjust the deck. My measurements were
Driver side: 2.5" off ground
Passenger Side: 2.75" off ground
Front: 2.5" off ground
Naturally i went to lower the height of the passenger side but the adjustment screw is frozen and is screwed to the highest setting. So i raised the driver side but it could only go up about a 1/8". I adjusted the level of the front wheels to help level the deck somewhat until i can hopefully work the adjustment screw free. The remining grass i cut looked better but still wasnt perfect. Now my question, would leveling the deck eliminate this line? The grass isnt sloped as if a blade were unlevel. All of the cut area is cut perfectly beides this line. What could be the cause?

thanks

You were spot on for checking the tire pressure first :good2: After that the deck needs to be level side to side and pitched about 1/4" lower in the front. The anti-scalp wheels are not supposed to ride on the ground but float about 1/4" inch above once you have the deck set correctly. If an adjuster is frozen you need to free it and get the adjustment you need. Soak it with your favorite penetrent like PB Blaster or something. It might need heat too to free it up. If you get it to within about 1/16" of an inch or so you won't be able to see tell the difference from it being perfectly level. If you still see your stripe you have an additional issue. You will need to check the blades underneath the deck and spin them wingtip to wingtip and make sure they line up. If one is out you have a bent spindle or possibly the deck itself is tweaked since you just replaced all the blades and I assume they are straight. Good luck :thumbup1gif:

I agree with what has been said so far. I would add that you need the check the front to back adjustment with the blades parallel to the direction of travel and for side to side they need to be perpendicular to the direction of travel. I happen to like Kroil for a penetrating oil.

thanks for the info guys. ill check everythign i can pretty soon but my main focus will be getting the adjustment nut unstuck. Looking at the diagram on the mower that shows what height the deck wheels need to be set, the front of my deck needs to come up a good bit. Its sitting pretty hard on the wheels while the back is perfect.

I've managed to free all frozen nuts and ill have the deck level tonight. When leveling the deck, it says to place the blade height selector knob at cut height 2, which is the usual height i cut my grass. What should be my ground to deck height?
Also, ill pick up a leveling gauge on my way home.

2 should be 2" but that is not as important as long as it is close and both sides are within 1/8" or less if you can get it that close.

ok I attempted to level the blades today, long story short: no success. Here is a picture of my problem.

This picture is after I had the mower deck perfectly level side to side and 1/8" lower front to back. I leveled the deck with a tape measure at 4 points. NEXT, I used the blade leveling tool. This was even worse. This caused the blade deck to be completely out of level when checking with a tape measure. Also, the cut was worse (no pictures b/c it was about dark out). It was like all 3 of the blades were at different levels now.

I noticed that all three blades don't line up. By that I mean, when I turn say the passenger side blade parallel to the axles; the middle blade is about a 1/4 turn off and the diverside blade is about 1/2 a turn off. is this how it is supposed to be?

Blade orientation to each other will hardly ever be the same and will change with mowing.

You don't recall hitting anything recently before you replaced the blades? I think something is bent like a spindle hopefully not the deck itself. Pull the deck and flip it over. Turn the blades so they line up tip to tip and then spin one 180 degrees and see if it stays at the same height. Do this for all 3 blades. I bet one of them will not line up on both sides then you have found the problem :thumbup1gif: You know the blades are straight so it almost has to be a spindle. All three blades should be a the same height in the deck shell relative to each other.

I don't recall hitting anything. I do have a new construction home which means there was some junk in the yard but I was careful when I was cutting and always walked the yard to remove any obvious debris before cutting. The yard has been object free for a year now. I noticed as the grass gets taller and thicker, my "line problem" gets worse. I'll check the blade level tonight or tomorrow. I do know that all 3 blades all do not line up (see my previous post) but I'll be able to check to see if the spindle is bent

I stopped by the local JD shop a little while ago and talked to a service manager. He seems to think that it is a bent spindle or the deck is bent where the bolts for the blade housing screw into the deck. He gave me a few things to try which will let me know if it a spindle or the mounting area. Either way it can be fixed with a new spindle or for $80 he has a plate that bolts to the deck and can straighten out the mounting area.
