Craftmen mower doesn't cut well on right side

I have a Sears mower with a 42" deck. The right side doesn't cut well as the left side. I have new mulching blades and the kit on the mower. I am not cutting much off the grass. The grass is burmuda and the grass looks like it is just bent over. I have to recut to make it look better.

Any suggestions?

    I checked the blade. It is installed correctly. The mandrel bearings were bad and dragging so the blade would not spin fast enough. I also noticed this was causing wear on the belt so I changed that also. I changed the mandrel and belt and the problem went away. Thanks for the suggestion.

Sounds like you may have made a common mistake, getting one or both of the blades upside down.

I have a Craftsman SL3500 42" riding lwan mower. the two blads make uneven paths ans the left blade makes a cut about 1/4" lower than the right blade. What do I do?


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.

42 inch mower cuts uneven, what is the problem?


Several things here could be the problem. Check to see if mower deck is level, measure distance on both side on a level surface. Check tire's for low air. If you've replace the mandrel's lately, some have a left & right side & if not put back together properly this will cause uneven cutting

2003 DLT3000 Craftsman riding mower. Air in tires correct, deck level front/back & side/side, new blades.. Still cuts uneven. Does this deck flex when cutting tall grass & how do I fix this...


when you put the new blades on did you notice if they were even with each other? the 42" decks have a tendency to "warp" inward on the left side. this causes the left blade to ride at an angle to the right blade - there is a tool to correct this, but not all shops have it - sometimes you can remove the deck, flip it over and wallop the inside edge of the left mandrel until the blades are even - a 2 lb. sledge works well for this

Deck is leveled, blades are fine,spindle not bent it still cuts


there was a problem with the lighter gauge decks [thinner steel], and the deck would actually bend inward on the left side. this would tilt the mandrel inward making the blade cut at a slight angle to the right blade - there is tool to straighten the deck [the left mandrel housing usually breaks, though] - some shops have this tool, others have never heard of such a thing - most sears l&g field techs have this tool in their trucks - i have the tool in my shop, but i have had luck with turning the deck over and whapping it a couple of times on the inside edge of the left mandrel until the blades line up

Sears Tractor Mower 42" is cut cutting lawn in two uneven strips


First, check the blade, it may be bent. If not, there is an adjustment nut (9/16) on each side in the middle of the deck hanger bracket. Get on level surface and screw each up or down to get blade tips the same height on each side.
