The GeoRipper 716, with Makita model EK7651H (Series 7) and maximum 16" digging depth (16), is the world's first 4-stroke handheld trencher.
The GeoRipper 716 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 GeoRipper FourStroke 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%. The GeoRipper 716 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 716 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 of the GeoRipper 716 make it a best-in-class handheld trenching tool and is ideal for landscapers, irrigation professionals, electricians and plumbers.
