There are three different types of snowthrower drives available: auger, wheel and track. With an auger drive, the auger (the snow gathering component of the machine) propels as the user pushes the snowthrower. With a wheel-propelled drive system, the user depresses the handle and the auger spins. Like a propelled lawn mover, the wheel system helps propel the snowthrower. With a track drive, the wheels of the snowthrower are replaced with rugged track treads, like a tank. It is great for maneuvering through heavy snow, because slippage is virtually eliminated.
If you don’t have a soil moisture probe, some simple guidelines can help you decide when to water. Water when grass changes from a green to a grayish blue color, when grass leaves begin to roll, when the grass stays down after being walked on, or when you can’t easily push a screwdriver down into the soil a half foot or so. Apply 1/4 in. of water and then check to see if the soil is wet down to 6 in. If it isn’t, make another application just so the soil is moist, but not wet or sticky.
