|
| This heavy duty driver is
ideal for rolling terrain where vertical alignment needs adjustment for
almost each post. The models HPD-16 SHC , HPD-20 SHC and HPD-24
SHC heavy duty design allows the operator to quickly align post and
reduce tractor shock. The positioning pivots are built to withstand
shock loads drivers produce during operation.
Fast and easy alignment is accomplished by two large 3" x 6" hydraulic cylinders. A separate two spool valve is easily accessible to the operator. One valve operates the fore and aft positions and the other operates the side to side positions. This valve operates on either open-center or closed-center hydraulic systems to match the operators tractor system, too. The "SHC" driver has stabilizer legs as standard equipment. The stabilizer legs are made of 2.5" x 2.5" tubular steel. They have independent height adjustment to allow for differences in terrain. The legs help to dampen the tractor tire bounce and reduce the hitch lift arm movement. |
