4 stroke = separate petrol and oil reserves
99% of all lawn mowers are four stroke
If you have a flat/level lawn to mow, then get yourself a 4 stroke.
quiter, smoother, more torque, less fumes, not as smelly, longer lasting
oil dip-stick to check oil level.
2 stroke = petrol and oil go into the same reserve.
need to mix in 2 stroke oil to the petrol before you can use it in the mower
If you have a slope, then you probably need to get a 2 stroke.
