NTA607/2007HD Contents Index Preparation and Setup This section helps you prepare your tractor and NTA607/ 2007HD Drill for use, and covers seasonal tasks, and task when the tractor/air drill configuration changes. Before using the NTA607/2007HD Drill in the field, you must hitch the air drill to a suitable tractor, inspect sys- tems and level the air drill.
Page 26: Hitching Tractor To Air Drill
Contents Index NTA607/2007HD Great Plains Manufacturing, Inc. Hitching Tractor to Air Drill Crushing Hazard: You may be severely injured or killed by being crushed between the tractor and air drill. Do not stand or place any part of your body between air drill and moving tractor. Stop tractor engine and set tractor parking brake before attaching cables and hoses.
Page 27: Hydraulic Hose Hookup
Only trained personnel should work on system hydraulics! Great Plains hydraulic hoses are color coded to help you hookup hoses to your tractor outlets. Hoses that go to the same remote valve are marked with the same color.
Page 28: Single-Line
Contents Index NTA607/2007HD Great Plains Manufacturing, Inc. Brake Hookup (Option) Two air drill braking (trailer braking) systems are avail- able: • Dual-line air system (Figure 6) with independent cable- operated parking brake (Figure 8), and • Single-line hydraulic (Figure 7) with independent cable-operated parking brake (Figure 8).
Page 29: Drill
Braking Hazard: Do not use the NTA607HD with a “single-line” air brake sys- tem. This drill is designed for transport speeds that require an air brake system to be “dual-line”. A single-line tractor sys- tem cannot charge the tank that powers the drill brakes.
