What is the best cost effective lawn mower for a teenage business?
I don't think the push reel mower will work or a corded one since I wouldn't want to ask for an outlet while doing a lawn if I don't know the customer.
If you're going to be mowing for hours every day, it would be worthwhile to get a self-propelled model. If you want to get a workout as you mow and the lawns are relatively flat, you can save money by getting a non-propelled.
A used mower may be good to start with, just make sure it's reliable so it's less likely to foul-up your mowing schedule if you have a breakdown.
I would say a basic mower (such as MTD or Yardman brands in the US) with mulching and bagging options and easily adjustable deck height would work well. Briggs and Stratton is a common engine brand on these types of mowers -- good and reliable.
Check the engine oil level often and change the oil regularly. Keep the air filter clean and the blade sharp. It's a good idea to invest in a spare blade so you can switch them and be right back in business without having to sharpen the blade immediately. (always remove the spark plug wire before changing a blade)
Good-luck
