I recently purchased a Fastrak SD 23/48 and am still getting the feel for how it responds to different terrain. I have a hill in my back yard that I need to get up and down so I can mow the flat area at the bottom of the hill. The grade on the hill is approximately 23 degrees with weeds and small rocky soil. Would I be foolish to try and drive my mower up and down this type of slope? Will the mower flip over backwards even with the wheels on the back of the bumper or will it just rare up and lose traction? My gut tells me it will go up and down the slope but my mind says don't try it. If anyone has experience or insight it would be greatly appreciated.
