Description
Handheld string trimmers cause backaches and vibrate hands numb when operators clear miles of fence lines and overgrown ditches. The DR Power Equipment 22 in 163 cc Manual Start Gasoline-Powered String Trimmer rolls across rough terrain on heavy wheels to eliminate carrying strain. It clears a 22-inch swath. Steep ditch banks require firm two-handed handlebar guidance.
A heavy-gauge formed steel unibody frame provides a rigid platform that withstands violent ground impacts and rock strikes. The cutting spindle is machined from high-tensile alloy steel and spins inside greaseable cast-iron pillow block bearings protected by labyrinth dust shields. Power comes from a Briggs and Stratton 163 cc overhead-valve commercial engine with a cast-iron cylinder sleeve and mechanical governor.

Combustion Engine Load Bench Telemetry
Chopping through dense waist-high weeds drops engine speed to 3180 RPM while fuel consumption measures 0.42 GPH. Spindle bearing housing temperature rises to 132°F after one hour of continuous fence line clearing. Cutting cord impact drag requires 3.6 Horsepower from the engine governor. Sound output measures 88 dBA at the operator handlebar position.
Rough Terrain Bounds Care Directives
Ranch caretakers, orchard managers, and municipal utility grounds crews clear rough fence perimeters fast using this wheeled trimmer. Do not operate this machine on steep 30-degree slopes because gravity oil starvation can damage splash-lubricated engine internals. Never use steel wire or cable in place of commercial nylon trimmer line.
- Check the spindle bearing housing and pump grease into the zerk fitting every 25 operating hours.
- Clean weed fibers and wrapped plant stems from the spindle shaft hub after each work shift.
- Inspect the engine air cleaner sponge and change crankcase oil every 50 hours of field service.
