3rd Season with WR147 and still very happy.
This is my third year with the same WR147 Landroid (M) after 3 years with a WR140.
A lot of people on here have complaints about their mower, but mine have been really solid - especially the WR147 with two front wheels. When I upgraded, I installed the Worx ToughTerrain wheels that added the right amount of weight to the unit which really reduced the amount of traction issues I experienced previously. I also ran new boundary wire (solid copper 18-gauge) that has eliminated wire missing errors for the past 3 years.
This year I made some minor modifications to our flower beds by adding metal edging which keeps the mower inbound.
I am keeping a close eye on the new AWD model, but so far I am very happy with my 3 year old unit. I have almost 400km on my WR147.
