Mowed first hay this year last week and after baleing it today I think i may have cut it to low. Although we used this mower all last year I never ran it. this year its all me though not sure if it was just the steep hills I was trying to mow or if it is cutting to low. I'm pretty sure there is not much u can do but just drop it and go? There has been nothing done to it at all from last year to this year and last year everything seemed fine. Most spots seem to be about 2in maybe 3in in places tall but a lot of spots on hills or turns it literally cut right into dirt.
