all of a sudden, the cut looks terrible

[bobbygedd]

my exmark always cuts beatiful. it was great when i packed it in friday, then sat morning, at my first stop, for no obvious reason, the cut looked horrible, i mean, very very bad, the lawn looked like it was chewed by a goat! i used my other machines to get me through the day. today, i scraped under the deck, sharpened the blades, checked the tension on the belts, fired it up, same problem! anyone know what it could be?

Did you put the blades on backwards by any chance? :D

Just kiddin, is the deck damaged, loose, or any other ways out of adjustment? (worker's fault) maybe banged into the trailer while loading, unloading?

have you hit any thing? if so you may have a bent arbor.. it is possible to have one bent (or a bad bearing) and not have any viberation.

Did you check to see if the decks pitch is correct.

What exactly does the cut look like? Is this a cut problem or a discharge problem? Can you see individual blade marks or sawtooth type patterns within the decks width. Are there large quantites of straglers or uncut blades of grass left behind. When you looked under the deck did you check if the blade tips were in alignment? Did the blades have any severe dings in them that might indicate the mower struck an object. Answering these questions can help determine your problem.
Hope this helps.

first off, what model is it? did you change ANYTHING? blades? deck height? let us know this and we can tell better what to do. also if no one helps you here, go the the exmark forum and ask terry or fred.

i changed my blades after i got mine and had the spacers all wrong and tried to compensate by lower the front of the deck. this got the rake of the deck ALL wrong and i had to double cut almost everything i touched. a few calls and posts and all was perfect.

How's the PTO clutch? Is it slipping under load?
