Granular Chemical Attachment

|
The granular chemical attachment can be used to deliver one or two different granular chemicals. The granular hopper (A) holds 32 kg (70 lb) of one type of chemical or 16 kg (35 lb) of insecticide and herbicide using a dual chemical hopper with divider (B). |
The application rate is determined by:

Turn knobs (A) on rear of granular meters to adjust the opening size. There are 80 increments which indicate the relative application rate. The delivery rate will increase from 1 through 79. Setting 00 closes the opening completely. A fluted roller or CHEMMIZER ™ meter delivers the granular chemical to the adjustable opening. The granular chemical flows through a given opening size at a nearly uniform rate regardless of rotor rpm. Therefore, SPEED has the greatest impact on application rate and resulting chemical concentration in the row. EXAMPLE: If planting speed is reduced from 10 km/h to 5 km/h (6 mph to 3 mph), chemical concentration will nearly double, since the delivery rate through the orifice remains nearly the same, while distance traveled in a given period of time has been cut in half. Therefore, twice as much chemical is placed on the ground due to the decrease in ground speed. Rotor rpm will not change the chemical meter delivery rate unless the seed population is changed significantly (± 25 percent or more from the original setting). The rate charts in this section are approximate and based on a planting speed of 8 km/h (5 mph). They are to be used only as a guide to determine a starting point for the meter dial setting. Always check rate of application as outlined in this section to confirm desired rate. |

To engage insecticide and/or herbicide drive, rotate knob (A) until spring-loaded knob engages spring pin in insecticide/herbicide drive shaft.
Most insecticides and herbicides readily accumulate moisture and may damage the granular attachment if allowed to remain in the hopper when the machine is not in use. Even during periods of operation, deposits of insecticide may build up in the hopper and interfere with working parts. Therefore, the hoppers should be checked every day for any material buildup and thoroughly cleaned if the machine is not to be used for a period greater than two days. See Service-End of Season section in machine operator's manual for cleaning instructions. IMPORTANT: Because the available chemical materials vary widely in consistency and composition, their "flow-ability" is affected by temperature and humidity conditions. It is important to calibrate each individual meter to the particular chemical being used. NOTE: Application rates greater than 227 gm (8 oz) per 305 m (1000 ft) at 10 km/h (6 mph) require installation of the high rate fluted roller in meter. Follow chemical manufacturer's application rate and meter setting recommendations as a starting point for the meter dial setting. If meter setting is not available from chemical manufacturer, use the charts in this section as a starting point for meter dial setting. |

CAUTION:
Agricultural chemicals can be dangerous. Improper selection or use can injure persons, animals, plants, soils, or other property. BE SAFE: Select the right chemical for the job. Use rubber gloves and respirator and apply the chemical with care. Follow instructions of the chemical manufacturer.
