I am a part timer considering selling/trading my 48" Exmark Turf Tracer hydro walkbehind for a 52" Exmark HP or Lazer. I even considered the 48" HP. I am looking to buy a rider to increase productivity which will hopefully allow me time for more jobs, as well as be more fun to use. It should also allow me to take on larger yards. Other than the obvious difference in length, can anyone give me any reasoning that I should buy one over the other. Because of the type of jobs I have, anything larger would be too much. I have about 15 residential accounts and they are 1/4 to 1 acre in size with both flat and hilly terrain. I will probably always have residentials because of my limited amount of time. Give me your thoughts!
