How to fix uneven cut

[yooperdave]

I brought my 6 year old 54" Toro ZTR mower in late last Fall to get the blades sharpened, tune-up and a wash. I was moving 75 miles away and wanted to get the mower as maintained as possible before relocating. Starting the Spring mowing season, it was more than apparent that the mower was not cutting evenly. The grass was growing like crazy as we received more than 8" of rain beyond the average for April. I cut the lawn to at least get the grass under control. What suggestions do you have to level out the cut? TIA

Well, the last time I "fixed" a mower for this... The owner had one rear tire inflated to 40psi!!!! The other was the correct 8psi. Once I deflated the tire, it was fine.

It could also be an issue in the linkage that the deck is suspended from.

But, if it happened all of a sudden, while not in use, I'd be looking for a flat or over-inflated tire

Or a loose blade bolt.

It helps to have a good blade height gauge.

I'd measure the DECK height side-to-side. And also measure the BLADE-to-GROUND height side-to-side. If your deck is bent or tweaked, this should show it.

As mentioned above, first be sure all tires are at the same pressure.

Are any blades bent?

If all of that seems OK, then you'll look at the linkages that the deck hangs from. I'd be surprised if TORO doesn't have a pretty simple leveling system -- need to check the manual online. I have a 60" Cub Cadet where you adjust hangers on a threaded-rod -- sorta like a turnbuckle assembly. Your hardware will determine how to proceed.

Also wouldn't be surprised if one side is more adjustable than the other. Check it out. Often designed with more flexible / adjustable hangers on one side.

I can't even figure out how to use that guage!
How about just a tape measure?

All good suggestions. The JD gauge is cheap and easy to use (Except for David? ). That pattern is so bad, I would pull the blades and make sure one of them isn't loose or badly bent. If none of this helps,you may have to consider a bent spindle, although that is almost impossible.

The gauge tool looks really handy to me! Problem is, I'd never be able to find it when needed.
