Section 3: Adjustments

Speed Change Sprocket

The Overseeder is designed with two drive speeds to 
accommodate different seed sizes and dispersal rates. 
They are high range (fast speed) and low range (slow 
speed). Use seed charts beginning on page 26 t
determine which range is correct for the seed you are 
dispersing. Some seeds work with both ranges.

High Range Set-up With Gauge Wheel Drive

Instructions below change seeder from low to high range.

Refer to Figure 3-2 & Figure 3-3:

1.

Loosen flange locknut (#1) and remove drive 
chain (#2) from speed change sprocket (#3).

2. Pull down on spring idler sprocket (#4) and remove 

driven chain (#5) from speed change sprocket (#3).

3. Being careful not to lose the washer behind the 

19/35 tooth sprocket (#3), remove 5/8" bolt, lock 
washer, 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 tooth 
sprocket in front of 35 tooth sprocket. Secure speed 
change sprocket with flat washer, lock washer, and 
5/8" bolt (#6). Tighten bolt to correct torque.

5. Drive chain (#2) should be 66 pitches long and driven 

chain (#5) should be 140 pitches long. If drive chain 
has 74 pitches, remove 8 pitches from it and add 
those 8 pitches to the driven chain.

6. Replace 140 pitch driven chain (#5) first and then the 

66 pitch drive chain (#2). Make sure the spring idler 
sprocket (#4) is pressing against driven chain (#5).

7.

Retention drive chain (#2) by pressing down on its 
idler sprocket. When tensioned properly, tighten 
1/2" flange locknut (#1) to maintain that tension.

Low Range Set-up With Gauge Wheel Drive

Instructions below change seeder from high to low range.

Refer to Figure 3-1 & Figure 3-3:

1.

Loosen flange locknut (#1) and remove drive 
chain (#2) from speed change sprocket (#3).

2. Pull down on spring idler sprocket (#4) and remove 

driven chain (#5) from speed change sprocket (#3).

3. Being careful not to lose the washer behind the 

19/35 tooth sprocket (#3), remove 5/8" bolt, lock 
washer, and flat washer (#6).

Refer to Figure 3-2 & Figure 3-3:

4. Make certain existing washer is still on the idler shaft. 

Install 19/35 tooth sprocket (#3) with 35 tooth 
sprocket in front of 19 tooth sprocket. Secure speed 
change sprocket with flat washer, lock washer, and 
5/8" bolt (#6). Tighten bolt to correct torque.

5. Drive chain (#2) should be 74 pitches long and driven 

chain (#5) should be 132 pitches long. If driven chain 
has 140 pitches, remove 8 pitches from it and add 
those 8 pitches to the drive chain.

6. Replace 132 pitch driven chain (#5) first and then the 

74 pitch drive chain (#2). Make sure the spring idler 
sprocket (#4) is pressing against driven chain (#5).

7.

Retention drive chain (#2) by pressing down on its 
idler sprocket. When tensioned properly, tighten 
1/2" flange locknut (#1) to maintain that tension.
