HI, I am wondering what I should charge to mow a 29,835 sq. ft. field. I need a brush hog but do not have one. I am using a lawn tractor with a 46 inch deck. The grass and weeds are at least 1 foot tall and the ground is very bumpy. It took me 2 passes to cut it. 1st pass about 2 hours because of moving rocks and debris and length of grass. The second pass took about 1.5 hours. This time includes getting off of tractor to scrape clippings out of deck. I cant believe how fast and the amount of grass clippings that builds up under the deck. I was charging by the hour at $45/hr. So I made about $157.50. What do you all think.
