Gardenkeeper Lars Johansson is said to be the proudest Walker user in Sweden. He's been using the mower for seven years, maintaining Ostra Torsas Kyrkogardsforvaltning, a church and cemetery in lngelstad.

The Walker mower operated by Grimslov High School in Grimslov, Sweden, knows what it's like to mow. The seven-year-old, diesel-powered machine has logged 2,400 hours in just about any type of mowing condition imaginable. Sports turf, common areas, and small enclaves and gardens have posed little challenge for the mower. The small inclines and other hilly terrain that highlights much of the school's 30,000 square meters of lawn haven't either.

On the banks of Lake Zurich sits Schloss Au, a beautiful property with a long and rich history. This magnificent castle with a background of military generals, celebrities and philosophers from all over the world was built and named in the 13th century, and has undergone many facelifts since then. The property is now publicly owned by the county of Zurich and is maintained by head gardener Carmene Pacceallo.

Meet Erwin Jakober. Twelve years ago this phrase meant a single man and his Walker mower. Today, this phrase means a company of 120 full-time employees and the most recognized lawn maintenance company in Switzerland.

Mike Barbero, owner of Real Estate Maintenance Co. in Boise, Idaho, was introduced to his first Walker 12 years ago. He purchased two at that time and has since purchased another. Identical in configuration, the three are powered by 16-hp Kohler engines and have 42-inch GHS decks. They all have one other thing in common: They're still going strong.
