I hear ya. I did no trimming. To treat breathing and extreme heat/sweating ( and increasing weight on chest ) I did park the tractor several times to go sit in shop A/C before going back at it.
I tried to mow yesterday but felt like I had a truck parked on my chest after 5mins being outside so I came back in due to AQ messing with my copd. Thank God my neighbor has a bailer, I might need it by the time I get to it..
