No More GASOLINE! 48V Riding Mower Helps With Homestead Chores
For years I used a 48V Ryobi ZT480e zero-turn mower converted to LiFePO4 to mow my grass. But after I moved to a new 35 acre homestead property, I really wanted something cheap with a normal steering wheel (not lap bars). The zero-turn had a trailer hitch, but for transportation, pulling small trailers and other…
