The GeoRipper GR16 Makita 4-stroke is the world's first 4-stroke handheld trencher. It uses the Makita EK7651H engine and digs up to 400 mm deep. It delivers several advantages over 2-stroke. No oil mixing is required, so contractors get simplified operation and no more engine failure due to improper mix. The 4-stroke engine eliminates the need for a separate mixed oil/fuel can. For easier starts, the automatic engine decompression valve is engineered into the cam gear to reduce pull-start force by 40%. This mini trencher also has lower noise at 92.7dB(A), smoother idle for continuous operation, and lower fuel consumption at only .45 gallons per hour. Additional advantages include a three-ring piston engineered for improved commercial engine durability, and reduced exhaust and intake carbon build-up for longer cylinder life. In addition, the GeoRipper GR16 Makita 4-Stroke has a five-stage foam-paper-nylon filtration system with Advance Direction Air Flow to provide cleaner air for improved engine durability.
 
The power and performance features make it a best-in-class handheld trenching tool and is ideal for landscapers, irrigation professionals, electricians and plumbers.
