Keep your lawn green with well-maintained equipment.
To keep blade balanced, make same number of stokes on each side, maintaining original cutting edge; unbalanced blade won’t spin properly.
Clean cut of sharp blade can keep grass healthier.
Some lithium-ion batteries now product as much power as gas mowers, 56 volts; they can charge in half an hour; one charge can last up to 45 minutes, enough to mow 1/3 acre.
If the same type battery is in other lawn equipment, recharge the second while mowing with the first.
