The 7700 is the bigger, heavier and faster version of the 5700. With many similarities and the rugged professional standards, it is designed with more weight band built to remove difficult material; while still using National’s industry leading battery configuration. The 7700 includes a 6700 series dual lift hydraulic slide plate. This adds weight to the front of the machine and allows the operator to easily adjust the height and angle of the slide plate without turning any wrenches! This precise angle adjustment of the cutting head with hydraulic control, keeps the operator safely seated while increasing blade life and adding 15 – 25% productivity. The unique handle design and valve system allows precise and accurate control of the machines movement and speed.
