Highline NT78/NT60 rock picker
Rock Pickers & Rock Rakes
Highline are the industry leaders in rock removal with the NT78/NT60 Rock Picker designed to be extremely durable and features a high-lift design of up to 2m so rocks can be unloaded directly into a trailer. Combined with the RR4300 Rock Rake, rock removal is even simpler as rocks can be raked into narrow rows prior to picking.
For over 60 years, the Highline Rock Picker has proven itself as a machine that delivers year in, year out. Designed with few moving parts, as well as extremely durable components, the Highline Rock Picker remains rock solid.
Exclusive to the industry, the Highline coil spring provides uniform loading over the reel operating range combined with the most compact mounting. This ensures that the spring mechanism is protected from rock damage, resulting in years of service. Replacing the springs just got easier with a simple threaded bolt to apply or remove tension to the spring.
The Highline Tine
The Highline rock picker tine is designed to follow the reel; this aids in raising rocks while allowing dirt to fall through. As well, the tines are extremely durable as they are hard surfaced on both the top and bottom leading edges to ensure hours and hours of operation.
Highline uses an industry exclusive gearbox that stands the test of time. The hydraulically driven gear case ensures large oil bathed gears set the reel at the desired speed. The hydraulic drive provides the flexibility to turn on, turn off, and reverse the reel from your fingertips.
Two Position Hitch & Box Frame Construction
The Highline hitch design moves the rock picker fully into view of the operator and the entire picking width is outside the tractor tracks. The hitch also advances the rock picker to a new level of transport convenience with a self-locking hitch. The self-locking design doesn’t require any pins or wedges; when you get to the field, the transport lock is required to be opened manually, returning to transport position engages the lock.
Highline is the only rock picker with a box frame construction. The front frame is built high to let rocks in, yet ensure the structure is strong enough to withstand the most difficult rocks that are removed from the field.
The Secret is in the Guided Reel: It is as simple as 1, 2, 3!
- The bogie wheels follow a special track to guide the reel for improved picking action. When the guided reel travels parallel to the ground surface, it pulls the rocks toward the apron rather than pushing down on the rocks.
- The guided reel lifts the rocks onto the apron.
- The guided reel delivers the rocks to the centre of the bucket and because the reel is guided it follows the same contour as the apron.
Not A Conventional Picker
Conventional round reels have only a few inches of positive picking action. When the round reel contacts a rock on the downward cycle, rather than sweep the rock towards the apron, it pushes down on the rock, 8″ and smaller rocks are often missed because the round reel buries the rock.
The High-Lift design feature provides options for operators to get rocks out of the way or off the field.
The High-Lift minimises wasted space from low flat rock piles by allowing higher more compact piles , or rocks can be transferred directly to a trailer for removal.
For fast and convenient rock removal, Highline rock pickers have a standard dumping height of 2.13m.
