My opinion only but I don't think it's anything you're doing but the design of the mower with that fat tire on the outside flattening out the grass is going to cause that problem no matter what you do. On my old New Idea mower the wheel is on the inside of the frame running on the area already cut, I'd consider bringing it back and get something with a better design. I think Vermeer makes good stuff but think that's really poor. Good luckHi all,
I just received my (new) Vermeer TM610 hay mower. Everything about it is working excellently, except that I'm having an issue with an un-mowed strip at times (inconsistently, though often the same spot in the field), seemingly no matter how much I overlap.
It happens on the left-hand side of my current pass, with some grass that was mushed forward by the far-right of the mower on the previous pass.

(I would think 12" was more than enough overlap?)
I'm still messing around with floatation and cutterbar height (I'm in New England, with small, hilly, sometimes rocky fields) - so can't figure out if maybe it's set too short or the floatation is too heavy (maybe both/either of those meaning the right side of the mower has too much down-pressure and is mushing the edge of un-mowed hay?) - though on the hillier, rockier field (not pictured), I was getting some inconsistent and high stubble height, so didn't feel like I could afford to back either of them off more. (And the problem also happened on that field, so doesn't appear to be field-specific.)
I am operating at 540 rpm. Not sure of mph, but so far I've used low-range 4 on a Massey 275. I've double checked that blades are correct orientation as well.
I did find that actually using a very minimal amount of overlap, rather than a lot, might have helped (not perfectly) - something to do with where the first disc is impacting the mushed strip of grass. But that kind of precision driving only is practical on the straightaways - of which a lot of my fields aren't 😅
Anyway, I'm all ears for advice here - whether it be Vermeer specific or not. I have used side-pull mowers before, but for the last 10 years have had a 3 point mower - so there is definitely a learning curve (no pun intended) on switching to a side-pull. Fully willing to admit there's something I'm doing wrong, just can't figure out what.
Thanks for any ideas!
