I am no expert with lawn mowers. Having moved to a house with a pretty big lawn, I got a ride on mower which broke down (and I was not very happy with it anyway as it did not collect the grass). Chose this for the roller, large capacity collector and variable speed.
The roller is good, and it mows brilliantly, not so sure yet about the benefit of variable speed but only used the mower twice so far, again not so sure about the grass-collector (comparatively in litres to others, this was one of the only one in 70's).
Starting is good, no problems so far. What else can I say? It does the job well, I cant think of any negatives.
