Most of the jobs I get for tractor bush hogging are 10 acres or less and usually have quite a few trees with low hanging branches that I need my small tractor to mow around, I use a 6' mower for those jobs with a 35 hp tractor and can mow all day on less than 10 gallons of diesel. If I get any bigger I am going to have to buy a batwing mower, but I really prefer the skid steer work and I may need to go up on my rates, I am just going to have to sit down and run all the numbers and see , but so far it is working out.
