Query: Too Small, Too Fragile

I purchased this mower for a very small yard which is not level. The mower would not roll easily over rough places in the yard, would not cut high grass without bogging down & shutting off. At one point when traveling over a rut in the yard, one of the back wheels flew off even though they had been tightened when the mower was put together. The mower might work well for trimming where grass is short & ground is very flat but is too light weight for anything more.
