There’s a lot that’s different about the original DR from the current models. The originals had big wheels with spokes, while we now use sealant-filled lugged tires. The older models also were designed such that the blade spun counter-clockwise and debris was discharged to the left. Now, the blades spin clockwise and discharge debris to the right. Older models also weren’t equipped with operator-presence safety switches — a requirement for power equipment today — that only allow the engine to run when an operator is at the helm.
Dennis, a DR Service Technician, says that it’s pretty common for older Field and Brush Mowers to come in for routine service. Though finding parts is sometimes a challenge, they are almost always in great condition and only in need of oil changes, belt replacements, or installation of current safety features. Original DR Trimmer/Mowers are common as well. DRs are built to last, even 25 years or more!
