Page 12: Setup Of Bait Box
Using Your Gopher Getter 1) Setup of Bait Box Your gopher getter is already setup for use with Elston gopher bait (milo w/0.5% strychnine). If you are using other types of poison such as oats or cracked corn or products with a lower amount of effective ingredients, you will need to replace the factory seeder slide with a seeder slide with a larger (7/8”) opening (Part # G4-208A). -
Page 13: Depth Of Coulter Blade
Using Your Gopher Getter 3) Depth of Coulter Blade The best depth is just deep enough to do the job. If it is too deep, it will be more difficult to get the gopher getter into the ground. If it is too shallow, roots will catch on the knife and tear up the ground as shown in Figure 8. -
Page 14: Angle Of Torpedo Tube

Make sure the coulter will not hit the frame as it runs though the soil and the hub of the coulter will not run though the dirt. - Page 15 Using Your Gopher Getter To avoid extensive damage to your machine, Never backup or turn while the machine is in the ground • Always replace the shear bolt with an identical grade 2 bolt. • Never over tighten the one inch bolt attaching the knife to the frame or the shear •...
