Description
Explore the engine deck of the New Holland CR10 and CR11 combines, including the CR11's 775-horsepower Cursor 16 engine. This technical walkaround explains the inline powertrain, reversible CVT drives, cooling airflow, machine balance, auxiliary PTO, and daily fluid and service checkpoints.

2:15 Efficient power flow to the rotors and feeder
2:46 Cooler box, rotary air screen, and engine-deck airflow
3:57 Right-to-left weight distribution
5:00 Inclined engine and oil-sump design
5:40 Engine service access
5:54 Rearward weight placement for header balance
6:46 Grain tank and air screen as noise insulation
7:22 Auxiliary PTO and belt-driven systems
8:39 Coolant, fuel, and compressed-air service points
9:28 DEF, hydraulic oil, and sight-glass checks
10:33 PTO gearbox oil and final daily checks
11:12 Rearward cooling-air discharge
Common questions covered in this video:
Why is the engine mounted lengthwise and at an incline? Its crankshaft, PTO, rotor gearbox, and feeder gearbox align closely with the systems they drive, reducing changes in power-flow direction and improving driveline efficiency.
How are rotor or feeder blockages cleared? The CVT drives allow the operator to reverse and then advance the rotors or feeder using a display procedure or console controls.
How does the cooling system keep the engine deck clean? Three fans draw relatively clean air from behind the grain tank through the rotary air screen and radiator system, then discharge it rearward across the engine deck.
Why is the engine offset to the right? The offset helps balance the large unload-auger assembly mounted on the left side of the combine.
Why are heavy components positioned farther rearward? Their placement relative to the rear axle helps counterbalance heavy front attachments, including 16-row chopping corn heads and an FD2 61-foot draper.
What does the auxiliary PTO drive? It powers belt-driven systems such as the unload auger, chopping system, and cleaning shoe, and it supports the feeder-drive hydraulics.
How should the hydraulic-oil sight glass be checked? Follow the operator's manual and decal; the video recommends checking with the engine off and the feeder house lowered because raised feeder cylinders hold oil and affect the reading.
How should PTO oil sight glasses be read? The combine should be level and should have been shut down long enough to obtain an accurate reading.
