I have tried pushing brush, trees, rocks, dirt, all with the front wheels off the ground. If it starts to veer off course, I just gently let the front end down and approach it again, not a big deal to me. I would have the best use of brake steering for my jobs in mowing, since my yard is about 10 acres. In the hot weather we have here, getting done faster is better. However, I guess it does not save a whole lot of time even at that. Was thinking more like the time saved with a zero turn mower. It may just be a relative thing as well.
