without stopping or shutting off the mower. How many consecutive hours have you mowed on a Z? I just spent today mowing a field for 4 hrs straight. I have no idea how many total acres I mowed but his total prop is 23. I sure got a lot of acreage covered in those 4 hrs using my 05 Toro Z Master. Best of all no trimming at all because they use gallons of roundup. I had a blast and made decent $$ too. Wide area mowing is fun.
