Old Tom wants some money to buy a toy, so Angela suggests he work for it - as a gardener. She lends him her old lawn-mower, and he soon has a job mowing the next door neighbour's lawn. However, mowing is hard work, so Old Tom attaches Lucy's remote-controlled toy to the machine and turns it into a remote-controlled lawn-mower. This is much easier, until he accidentally switches controls with Billy - then the mower zooms off out of control, with Old Tom holding on. The mower and Old Tom zoom around town, cutting a zigzag maze through the town park - but the Mayor, far from being angry, is delighted with the new feature and pays Old Tom for his work. Old Tom rushes off to the shops, but instead of buying the toy he wanted, buys a new mower for Angela.
