John Deere 1050C - Manual (Page 4)

Three-millimeter perforations in the hood and side shields act as a “first
filter,” preventing entry of most airborne debris.
Variable-speed fans run at speeds appropriate for operating conditions to
preserve power and precious fuel.
1. Five-fin-per-inch radiator core resists plugging. Inline core tubes
make clean-out easier.
2. Hinged front grille allows easy access for maintenance and cleaning.
3. Corrugated screens and hydraulically driven fans take the heat away
from the transmission oil and engine coolant. Reversing fans engage
automatically every 30 minutes to blow away refuse and help prevent
plugging. Fans can also be operated manually from the seat as needed.
