GRAIN DRILLS

SEEDING QUALITY

Sunflower Grain Drills

All-Purpose Grain Drills

 

For years Sunflower multi purpose grain drills, have featured a unique frame design and delivered unmatched flexibility and seeding performance in all field conditions.

The 9312 Series Grain Drills are ideal for pastures which require re-seeding due to drought or over grazing because this tough, compact grain drill can handle all of their conventional and no till seeding needs.

For maximum productivity, Sunflower developed the 9412 three-point mounted all purpose grain drill line.

The 9412 is one of the only mounted true no-till grain drills on the market. The 9421 multi-purpose grain drill features a narrow transport width compared to wide, rigid, mounted designs that are difficult to move between fields.

The Sunflower 9433 Grain Drill can be tailored to your operation and be your single source for conventional seeding right through no-til.

The Sunflower line truly is "Seeding Quality."

Engine

Engine

The Tier III Cat® C15 and C18 ACERT® technology engines supply significant power when compared to other tractors in its class. The real test of an engine is when it maintains power, while lugging through tough conditions and encountering heavy loads. The MT900C Series models have the built-in deep torque reserve that today’s farmers demand.

ACERT®

ACERT®

While most engine manufacturers resorted to other methods to meet Tier III standards, including exhaust gas recirculation (EGR), Caterpillar took a completely different path, developing its own unique technology. ACERT technology allows precise control of the combustion process ensuring emission standards compliance without sacrificing horsepower, performance, or reliability.

  • 923 cubic inches (15.2 L) and 1,106 cubic inches (18.1 L) displacement
  • 42% torque rise
  • Peak torque is reached at 1,400 RPM.
  • A more efficient fuel system achieves maximum fuel economy and lower emissions.
  • Mid-support of the cylinder liners decreases vibration, reduces engine noise, and reduces power lost by piston blow-by.

Transmission

Transmission

Built from the robust design of the Challenger track tractor transmission, the MT900C Series is equipped with a Cat Powershift transmission featuring push-button control for 16 forward and 4 reverse gears.

With eight gears providing a 4 to 9.3 MPH (6.5 to 14.9 kph) working range, the MT900C Series provides the responsiveness and productivity your applications need. Since getting the job done means being in the field, Challenger offers one of the fastest transport speeds of any articulating tractor at 24.6 MPH (39.6 kph) meaning more time in the field and less time on the road.

The CAT transmission and engine are continuously communicating to provide optimum productivity and performance. The transmission senses the load on the engine and adjusts to deliver smoother shifts and longer life for all components.

Power Management (PM)

The Power Management system is designed to get the job done faster and more efficiently.

This control coordinates engine speed with transmission gear to match an operator’s needs with field conditions. Maximum Power mode keeps the engine in the peak power range for heavy draft loads. Constant Ground Speed achieves an operator-designated ground speed while automatically controlling shifts and engine speed to maximize fuel efficiency.

Hydraulics

Hydraulics

Challenger MT900C Series tractors offer more flow, more versatility, and more efficiency than ever before.

Standard features include 4 remote hydraulic valves with a 5th and 6th valve available as an option. The MT900C Series feature a closed center, load-sensing, pressure- and flow-compensating system, a 43.5 gpm (164.7 L/min) pump standard, and a 59 gpm (223.3 L/min) pump option.

The operator can electronically adjust flow rates, timed detents, and individual valve operation with precision from the cab’s Tractor Management Center display.  The operator can also direct continuous flow of up to 36 gpm (136.3 L/min) through any one coupler. This is particularly important in seeding and planting applications where uninterrupted oil flow to hydraulically driven motors is critical.

Operator Area

Operator Area

One of the first things you’ll notice about the cab is its size. Leading the industry, it boasts 108 ft3 (3.06 m3) of comfort, convenience, and control. You’ll appreciate the 67.5 ft2 (6.2 m2) of usable glass area, the slim profile dash, and the short sloping engine hood which combine to deliver an unobstructed, panoramic view.

Additional comfort and convenience amenities include: 

  • An optional VRS semi-active, heated operator’s seat that provides continuous real-time automatic damping force in response to varying terrain.
  • An electronic dash showcasing all major tractor and engine functions, including the selected gear, engine RPM and machine hours.
  • The Surround-Flow™ ventilation system keeps you comfortable and productive with 12 vents strategically placed throughout the cab.
  • Optional Nightbreaker HID lighting provides clear definition of detail from a greater distance than normal halogen lights.
  • The largest and most comfortable instructor’s seat in the industry is standard, but can also fold down and double as a workspace to use your laptop.

Tractor Management Center (TMC)

Tractor Management Center (TMC)

Challenger’s unique Tractor Management Center (TMC) has an intuitive ergonomic design that puts all key functions at your fingertips including the all new ISOBUS TMC display. As the international standard for electronic communications used in agriculture, ISOBUS allows any compatible tractor to communicate with any compliant implement, no matter the manufacturer.

The TMC display allows the operator to monitor all tractor, engine, and transmission functions, as well as check and adjust hydraulic flow settings all from one single location. It can control all connected ISOBUS compatible implements - eliminating the need for additional monitors or control boxes in the cab. Simply plug and play for seamless operation.

Frame and Axles

Frame and Axles

The MT900C Series ensures a perfect balance of strength and agility. It boasts the heaviest, most robust frame in the industry which serves as the foundation for the machine. The driveline is one of the largest in the industry and connected to the largest standard diameter axles. The size, strength and weight help to efficiently put power to the ground without hampering the maneuverability of the tractor.

  • Tri-point oscillation provides up to 13 degrees of movement for even distribution of weight and power
  • 42 degree turn angle provides the best-in-class 16 ft (4.87m) turning radius on 710/70 R42 tires
  • Axle diameter is 5.7 in (145mm), largest standard on the market
  • Optional electro-hydraulic differential lock
