  • Smaller tank for gas so refuelling will be more frequent and it is important not to allow the fuel to deplete completely.
  • Always make sure there is plenty of fuel in it and check the fuel level regularly
  • Some mowers had trouble with starting the engine after refuelling so again it is important to keep an adequate level of fuel in it at all times
  • Question marks of warranty’s being fully honoured.
  • Routine maintenance is required

  1. This is the best product review I have seen on the Snapper 21 inch mower. I especially like the comparison chart so at least I can compare this Snapper Front wheel to other models. Briggs and Stratton has the reputation of being the best as far as engines go. I own a Black and Decker mower which is quite old now and I have been meaning to change to Snapper for the last few weeks, this review as been a great help! Cheers for all the detailed information, plus the attractive prices – no need to look elsewhere. Keep up the good work Paul!!!!!

    • You are more than welcome and thanks a million for the compliment! Best of luck also with the changeover to the Snapper 21 inch mower – you wont be disappointed!

      Take care – Paul

  2. Good afternoon, at least where I am, I love snapper mowers. The one I own now, (don’t know what model but is a push one) i have had four 4 years. I’m in my 50’s and i don’t know if i have ever had a mower last more than 2 or 3 years. I would definitely recommend buying a snapper, in my case it wasnt more money, but if it was, looking back I would pay more money for this product… seriously for real….and the upgrade to the self propelled as I get older looks even more attractive
