Great Plains Manufacturing, Inc. Table of Contents Index 9 Index 403-362M Operating Instructions This section covers general operating procedures. Experience, machine familiarity, and the following information will lead to efficient operation and good working habits. Always operate farm machinery with safety in mind. Pre-Start Checklist Perform the planter pre-start checklist, and the following steps before transporting the YP24/YP40 DF/seeder planter to the field.
10 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Transport Loss of Control Hazard: Ensure that the towing vehicle is adequate for the task. Using an inadequate tow vehicle is extremely unsafe, and can result in loss of control, serious injury and death. 21 The planter can weigh over 15 000 kg (33,500 pounds), depending on configuration and material load. The tractor unit MUST be rated for the load.
Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 11 Loading Materials Seed and fertilizer may be loaded manually or via auger. Walkboard/ladder details, and auger height requirements are shown in the Operator manual. Before ascending the ladder for loading or auger outlet control: • Check that the walkboard is closed and latched. Although the YP40F walkboard has a side extension, the latching is identical to the standard walkboard.
12 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Loading Fertilizer Check that calibration and clean-out doors are closed at meter (page 35). Refer to Figure 4 1. Lift the handle U-bolt shackle 3 until 5. the hook 2. Inspect the strainer basket clean as necessary. 6 4 releases from the for debris. Remove and Confined Space Hazards: Leave strainer in place for all routine operations. Do not enter hopper for routine operations. Risk of entrapment and rapid suffocation.
Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 13 Changing Seed Box or Hopper This topic in the Operator manual does not generally apply to the YP2425F-2470, YP4025F-1630 and YP4025F-1670. Using a standard 82bu hopper requires substantial disassembly of the planter seed cart structure, and modifications to the air system. Using a 150bu hopper or dual 200 gallon liquid fertilizer system further requires removal of the entire fertilizer ground drive.

18 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Fan Circuit Operation Refer to Figure 7 Three hydraulic hoses serve the fan, and must be properly connected for the fan to operate in the correct direction 1 , at recommended speeds, and without damage. See “Hydraulic Hose Hookup” in the 401-406M (YP24) or 401-571M (YP40) Operator manual. 1. Always connect the case drain line 2 2 3 4 first. This line protects the outer shaft seal of the hydraulic motor.
Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 19 Fan General Operating Information Adjust the fan rpm and butterfly valves to provide sufficient air flow for consistent transport of seed and dry fertilizer. Suggested values are shown at right. Fan rpm is controlled by the tractor circuit, and reported by the seed monitor. Always start the fan with a low flow setting. Gradually bring fan up to the target rpm.
20 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc.

Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 23 Setting Material Rates Setting Seed Rate Seed rate setting for the YP2425F-2470, YP4025F-1630 and YP4025F-1670 planter is identical to the standard YP24 or YP40 planter.
24 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Setting Variable Rate Gearbox The variable rate gearbox allows an infinitely variable meter drive speed to attain a wide range of application rates. The ratio of gearbox input speed to output speed is controlled by the position of a gearbox control arm. The control arm has an indicator that points to a scale marked in degrees. The Fertilizer Rate chart shows the rate for each five degrees of arm rotation.
Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 25 Meter Calibration The fertilizer rate charts are based on a representative 11-52-0 dry granular fertilizer. Many factors affect meter rates including fertilizer density, granularity, texture, adhesion, humidity and field conditions. 2 Great Plains recommends calibrating for the exact material being applied.
26 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Row Sample Calibration This method requires 16 or 24 containers each with a capacity of about 1% of a hectare or acre, and a scale capable of precisely weighing the heaviest empty container plus the sample size (or all the containers at once). 7. Turn on the seed monitor system. Although not used for calibration, you need the monitor to display fan rpm. 8. Weigh the empty sample containers (the “tare”). Refer to Figure 12 9.
Table of Contents Great Plains Manufacturing, Inc. Index Adjustments 27 Meter Sample Calibration 18. Weigh any container(s) required to hold the sample on the scale. Refer to Figure 14 19. Place a tarp under the fertilizer meter. Support the corners or edges so that no material can spill. Refer to Figure 15 20. Open the meter calibration door. The calibration door is the rear door, furthest from the DRIVING gear. Material Loss Risk: Do not open the (forward) door under the DRIVING gear.
28 YP2425F/YP4025F Table of Contents Calibration Adjustment Once a sample has been taken, two steps remain: a. Calculate the current rate. b. If needed, calculate and apply an adjustment to the gearbox setting. Calibration: Rate Calculation 30. If not already done, weigh the metered sample. This is the gross weight. 31. Subtract the weight of the empty containers (the tare) from the gross weight.
Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 29 Coulter Adjustment The frame-mounted coulters standard on the YP2425F-2470, YP4025F-1630 and YP4025F-1670 are configured for “zone” application: 5cm offset from seed furrow, and 5cm depth, or “2x2”in. As blades wear, or under unusual field conditions, you may need to adjust the coulter depth. If the depth is adjusted, the applicator needs to be adjusted as well. 4 Coulter Height Adjustment Refer to Figure 17 1. Raise the planter.
30 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc. Frame-Mounted Coulter Force In normal operation at target running depth, the spring is at full extension or only slightly compressed. It compresses briefly as obstructions and denser soil are encountered. Coulter springs are set to 181 kg (400 lbs). In normal operation at target running depth, the spring is at full extension. It compresses briefly as obstructions are encountered.
