The Willows have moved out to a somewhat remote house with a fair acreage. Derek misses his friends at his old home, and wants to get a train ticket and go visit, but money is tight. When the family lawn mower dies, Derek and his brothers and sister find an old rotary mower in the shed and start to tackle the huge job of mowing. It's much easier when they find that the mower is magic, and it happily drags them all over the yard, as well as over some hedges. Can Derek keep the lawn under control so the family doesn't have to buy a new mower, and he will have enough money for a train ticket?
The second in a series (Hamster Magic is first) this was a fairly amusing Stepping Stone book vaguely reminiscent of the work of Ruth Chew. Since I have a rotary mower, I had to read it.
