Model H7 - Tree Digger
GK's H7 Bare Root Digger has proven itself year after year, in field after field as the backbone of GK's product line and the premier bare root tree and shrub digger in the industry. This workhorse gets the job done fast and efficiently, and it's extremely easy to operate and maintain.
- With a very low center of gravity, the H7 maneuvers well in all kinds of terrain and ground conditions.
- The H7 has the power needed to make tough digging jobs easy - it puts out just over 440 lbs. of torque at 1,500 RPM.
- Designed to straddle rows, the H7 has “on-the-go” track width adjustment while the tunnel offers a full 9’ of vertical clearance.
The H7 travels at 6 miles per hour, covers an area of 12’ 6” and will pull the ½” thick sold steel U-blade for a complete length of 21’ 6” – all while carrying 80 gallons of diesel, driver and blade. The variable speed oscillating shaker arm efficiently removes soil and debris from the root structure for a fast and efficient operation.
