18Section 3: AdjustmentsOS1548 and OS1572 Overseeder (S/N 166724+) 308-303M 2/29/12Table of ContentsSection 3: AdjustmentsSpeed Change SprocketThe Overseeder is designed with two drive speeds toaccommodate different seed sizes and dispersal rates.They are high range (fast speed) and low range (slowspeed). Use seed charts beginning on page 22 todetermine which range is correct for the seed you aredispersing. Some seeds work with both ranges.High Range Set-up With Gauge Wheel DriveInstructions below change seeder from low to high range.Refer to Figure 3-2 & Figure 3-3:1. Loosen flange lock nut (#1) and remove drivechain (#2) from speed change sprocket (#3).2. Pull down on spring idler sprocket (#4) and removedriven chain (#5) from speed change sprocket (#3).3. Being careful not to lose the washer behind the19/35 tooth sprocket (#3), remove 5/8" bolt, lockwasher and flat washer (#6).Refer to Figure 3-1 & Figure 3-3:4. Make certain existing washer is still on the idler shaft.Install 19/35 tooth sprocket (#3) with 19 toothsprocket in front of 35 tooth sprocket. Secure speedchange sprocket with flat washer, lock washer and5/8" bolt (#6). Tighten bolt to correct torque.5. Drive chain (#2) should be 66 pitches long and drivenchain (#5) should be 140 pitches long. If drive chainhas 74 pitches, remove 8 pitches from it and addthose 8 pitches to the driven chain.6. Replace 140 pitch driven chain (#5) first and then the66 pitch drive chain (#2). Make sure the spring idlersprocket (#4) is pressing against driven chain (#5).7. Retention drive chain (#2) by pressing down on itsidler sprocket. When tensioned properly, tighten1/2" flange lock nut (#1) to maintain that tension.Low Range Set-up With Gauge Wheel DriveInstructions below change seeder from high to low range.Refer to Figure 3-1 & Figure 3-3:1. Loosen flange lock nut (#1) and remove drivechain (#2) from speed change sprocket (#3).2. Pull down on spring idler sprocket (#4) and removedriven chain (#5) from speed change sprocket (#3).3.

Drive chain (#2) should be 74 pitches long and drivenchain (#5) should be 132 pitches long. If driven chainhas 140 pitches, remove 8 pitches from it and addthose 8 pitches to the drive chain.High Range Set-up with Gauge Wheel DriveFigure 3-1Low Range Set-up with Gauge Wheel DriveFigure 3-2Sprocket Alignment with Gauge Wheel DriveFigure 3-36.
