I too just bought one these and had the same thing. I used it twice to pull some logs around the house the first time and light was still yellow. A few days later I used to mow a section of the yard (had to try it even though there isnt really any lawn yet) and used for about 1 hour. When I parked it the light was green but went to yellow the next morning.
