Hi my john deere l100 will not pick up the grass clippings, we just had it services last year before winter, when the tech was here it worked just fine. Now it will not pick up the clippings

Is it cutting fine or is that bad too? Check your chute to make sure there is no blockage.

Yes it is cutting just fine, there is no blockage. Do you think he may of put blades on wrong? I just don't know

Maybe you have mulching blades on the mower.

If there is no blockage you should call that tech and ask if he changed your blades. Jsfocke may be onto something.

Maybe you have mulching blades on the mower.

How can I tell
