Rear Finish Mower Finish mower not cutting right

[IslandTractor]

I saw a neighbor having the same problem with a JD riding mower. All the belts seemed tight and the blades were OK but the grass was very tall (12-18 inches) and I think he was just mowing too fast.

Another reason to get a flail mower! (You can bog a flail down but you don't get these uncut areas even if the grass is too tall).

When my finish mower does this, it means I've picked up a piece of plastic bale twine and its wrapped arround one of the spindles. Its comes and goes as it winds around and can get ejected.

I did some tests on it in a field we have. It did the same backwards or forwards. I was inspecting the blades, and I can push them in separate ways slipping the belts fairly easy. I don't know if that's right or not. Also could blade sharpness be an issue.

I'll try it on normal lawn height grass today. It did cut a lot better when I mowed at about .2 miles an hour or less. It's just unbearably slow when there's 6 acres

Just finished mowing on a lwan. the grass was pretty short, and it mowed better, but some parts on that right side it still leaves a little strip. And when the grass was a little higher in an area it left a strip. I went slower and that helped. I think something like the belt might be loose, from my previous post. But I don't know enough to make a final judgement

You found the problem, belt slip. You will need to adjust or replace the belt if badly worn. If the belt slips it will ware faster than normal.

If you're leaning toward blade slippage, why not just tighten it up (or tighten the tension, assuming there is a spring) and try some more?
