Towed Scrapers:

Follow manufacturer's instruction in attaching and using scraper.

9030 Tractor/Scraper Application Guidelines:

IMPORTANT: Operating tractor with three scrapers requires tractor be equipped with hydraulic trailer brakes. Reference "Towing Loads and Transporting with Ballast" Section of Operator's Manual.

Scraper Operation Recommendations:

• Do not downshift or upshift transmission when in dig area.
• Limit depth of cut to maintain a loading speed higher than 6.4 km/h (4 mph). For maximum power performance with 9430 and 9530 tractors operate in

7th forward gear or above, and for 9630 tractor operate in 8th forward gear or above.
• Maintain minimum engine rpm of 1850 or higher.
• Ballast tractor correctly to maintain optimum wheel slip of 8-12%.
• Shallow cuts at higher speeds will extend drive train life and increase overall productivity.

• Use APS (Automatic Powershift) for transport mode, not during loading or digging.
• Use IMS (Implement Management System) to combine downshifts/upshifts, raise/lower scrapers or other functions when returning to dig area or to/from transport part of cycle. (See Implement Management Section.)
• Drawbar height should be set so scraper cutting edge hits the ground before the scraper bottom. See Scraper Operator's Manual.

• Load scrapers going downhill when possible.
• Disengage differential lock when making turns.
• Use of differential lock should be limited to tough spots or wet areas.
• Do not downshift below grounds speeds of 6.4 km/h (4 mph) when under load.
• When downshifting going downhill, do not exceed recommended engine rpm.
