Speed Change Sprocket
The All Purpose Seeder is designed with two drive
speeds to accommodate different seed sizes and seed
dispersal rates. The two drive speeds are high range
(fast speed) and low range (slow speed).
High Range Set-up
Refer to Figure 3-4:
1. Loosen 3/8" flange lock nut(#1) and drive tension
sprocket (#2). Remove drive chain (#3) from speed
change sprocket (#6).
2. Remove 5/8” nut (#4) and 5/8” flat washer (#5).
3. Pull idler sprocket (#8) away from driven
chain (#7) and remove driven chain.
4. Rearrange speed change sprocket (#6) so that the
larger 35 tooth sprocket is behind the smaller 19
tooth sprocket as shown.
5. Secure sprocket with 5/8" flat washer (#5) and
5/8" - 11 nut (#4). Tighten nut to correct torque.
6. Drive chain (#3) should be 65 pitches long and driven
chain (#7) 101 pitches long. If drive chain has 73
pitches, remove 8 pitches from it and add those 8
pitches to the driven chain.
7. Replace 101 pitch driven chain (#7) first and then the
65 pitch drive chain (#3).
8. Make sure idler sprocket (#8) is pressing against the
driven chain.
9. Retention drive chain (#3) by pressing down on idler
sprocket (#2). When tensioned properly, tighten 3/8"
flange lock nut (#1) to maintain that tension.
Low Range Set-up
Refer to Figure 3-5:
1. Loosen 3/8" flange lock nut(#1) and drive tension
sprocket (#2). Remove drive chain (#3) from speed
change sprocket (#6).
2. Remove 5/8” nut (#4) and 5/8” flat washer (#5).
3. Pull idler sprocket (#8) away from driven
chain (#7) and remove driven chain.
4. Rearrange speed change sprocket (#6) so that the
larger 35 tooth sprocket is in front of the smaller 19
tooth sprocket as shown.
5. Secure sprocket with 5/8" flat washer (#5) and
5/8" - 11 nut (#4). Tighten nut to correct torque.
6. Drive chain (#3) should be 73 pitches long and driven
chain (#7) 92 pitches long. If driven chain has 101
pitches, remove 8 pitches from it and add those 8
pitches to the drive chain.
7. Replace 93 pitch driven chain (#7) first and then the
73 pitch drive chain (#3).
8. Make sure idler sprocket (#8) is pressing against the
driven chain.
9. Retention drive chain (#3) by pressing down on idler
sprocket (#2). When tensioned properly, tighten 3/8"
flange lock nut (#1) to maintain that tension.
