8 inch stripe longer grass being left?

[Whynot]

where exactly does this 6-8" stripe appear? Left side, middle, or right side.....? A picture shooting at ground level might be better...

Right hand side. In heavier grass it is much more noticeable

The make and model or the manufacturer label information is needed from you. We are basically guessing at this point. Help us help you. There is no one answer to your query.

Is this an equipment dealer purchased mower or a "big box store" purchased unit? (Lowe's, Home Depot, Tractor Supply Co. etc.)

When I worked as a Service manager for a JD dealer, we occasionally received new riders with bent deck housings from mishandling when loaded on the shipping platform crates at the factory. Many had to have the deck shell replaced.

This issue needs to be properly addressed with the salesman who sold you the unit if it was at a dealer. Or it needs to be addressed by the repair shop Service Manager. They need to own this problem and not play "kick the can" with it.

They need to pick it up and take it to the repair shop, actually mow with it and figure out the problem(s) Sending a mobile repair person is usually no good in this situation and just cost you more money.

I have the 60inch deck. 2024 bought new last summer. I forget the model. I can get if relevant. This issue was fixed last fall under warranty. The tech came out last fall to fix a loose bolt on the steering handles So it wouldn't start. I mentioned to him I waited my whole life to get a good professional grade zero turn and look what it does. My BF bought me this high end model with seat Suspension and everything. I show him I need to make two passes so effectively I only have a 2.5 ft deck. He did something. Problem went away. I probably only put max 20 hours on after the fix. Problem came back again this spring After around another 6 hours. If I make one pass with mower in anything higher than 4 inches I get a 6/8 inch wide stripe that hasn't been cut or maybe partially cut. I replaced blades hoping for a fix. No luck.. now I am supposed to bring it back to shop yet again or pay 150 an hour from when they leave the shop AND 1.30 per miles to have them come out again. So I will need to load on trailer and take it back over. Anyone here have any idea how to fix? Is this something permanent with this mower? I am so incredibly disappointed.

pic but needed to be much reduced otherwise too large

I suspect one of the spindles is seized a bit and/or Belt is too loose. Get it up in the air and with Blade rotation OFF, reach under and see if they rotate with equal ease. Sorry for your luck. Check what was done on last service call and get your BF to man up.

I have had similar problems in the past if the deck belt was not routed correctly. Some decks have a belt routing diagram on them for reference.

The other possibility is the deck belt is a "generic" and/or is not the exact length. If a deck belt is not correct the blade speed is reduced, especially in heavy grass. The heavier the grass the worse the cut.

Never did see your machine information. We need the machine make and model along with the machine label information. The is no real answers without this information, just guessing and speculation.

Ditto on the make and model #...

A 60in deck usually = 3 blades. Maybe the blade on the right is missing, loose, upside down as previous poster stated etc. Pictures and more pictures along with make and model #. Help us help you.

I need make and model of your mower. A pic would also be nice. Maybe I can help you.

I am with the upside-down blade or a loose blade

Did this problem just start happening, or has it always done this? -- If it has always done this, it could be a bad deck where one of the spindle cut out is wrong. Is the belt on correctly. Belt maybe slipping on the blade that is not cutting the 6-8 inch strip. Go thru the middle of your non cut grass and see which blade is not cutting.
make sure under deck is clean. Make sure all the bolts on blades are tight, blade could be slipping. Raise the deck and place all blades in a straight line across deck and check the distance between each blade.

do you know the name brand of the mower and what is it called or a number of it, meaning like Cub Cadet, yellow horse, something to head us in somewhere of the right direction, the size of the deck, 48,54,60,61, and where is the strip being left, right, center, I have seen some that come from shop that the blade if upside down thus causing

Likely a 42" deck with 2 Blades.
