TORQUE SPECIFIED IN FOOT POUNDS - This chart provides tightening torques for general purpose applications when special torques are not specified on process or drawing. Assembly torques apply to plated nuts and capscrews assembled without supplemental lubrication (as received condition). They do not apply if special graphite moly-disulfide or other extreme pressure lubricants are used. When fasteners are dry (solvent cleaned) add 33% to as received condition torque. Bolt head identification marks indicate grade and may vary from manufacturer to manufacturer. Thick nuts must be used on grade 8 capscrews. Use value in [ ] if using prevailing torque nuts.

Assembly Instructions
It is very important that your new 2131 Wing Coulter Chisel be properly assembled, adjusted and lubricated before use. Illustrations to assist with the assembly process are provided in “Standard Specifications” on page 2-1. They show proper shank and light mounting bracket spacing. Illustrations in this section show proper assembly procedures. Remove paint from grease fittings. Replace any grease fittings that are damaged or missing. Be sure to return screws, clips, etc., to their original locations.

To insure alignment of assemblies, leave the nuts loose until completion of final assembly. Use lock washers or flat washers as specified. Spread all cotter pins. After completion of final assembly, tighten all nuts evenly to prevent misalignment, distortion or binding. Tighten all screws and nuts to the recommended torques (See Table 2-1 and .See Table 2-2).

Landoll 2131 Hitch Installation

1. Attach the hitch weldment to the front of the frame using hitch pins, 1-8 hex lock nuts, and 1/2 x 2-1/4 slotted spring pins (See Figure 3-1.)
2. Move the jack to the forward mounting tube and rotate to parking position to support the front of the hitch.
3. Insert a 3/4-10 x 10-1/2 hex head cap screw into the hose holder tube on the right side of the hitch from the bottom side so the threads point upward. Hold in place with a 3/4 prevailing torque flange nut with the flange pointing upward as well. Do not tighten this cap screw, so the hose holder bracket may pivot freely in this joint.
4. Slide the hose holder bracket over the screw and secure with another 3/4 prevailing torque flange nut.

Landoll 2131 Depth Stop Tube Assembly

1. Attach the depth stop mount plate to the shank lift using 3/8-16 x 1-1/4 hex head cap screws and hex lock nuts.
2. Lay the depth stop tube assembly on top of the center frame. Insert a 5/8-11 x 2-1/2 hex head cap screw in the rear hole of the tube assembly from the left side (See Figure 3-3.) Install a 5/8-11 hex lock nut on the screw. Do not over tighten, as the depth stop must pivot on this screw.
3. Insert 90o elbow fittings in the back of the limit valve and a straight adapter in the side nearest the center of the machine.
4. Using 5/16-18 x 5 hex head cap screws secure the front end of the depth stop tube assembly to the top of the frame mount with the depth stop guide, slide pad, and 5/16-18 hex lock nuts. Attach the limit valve to the bottom side of the center frame mount using these same screws.

Landoll 2131 Tractor Preparation
The Landoll 2131 Wing Coulter Chisel is designed to be pulled by tractor equipped with a double lip or clevis type hitch. If your tractor is not equipped as such, you need to purchase the hitch from your local tractor dealer. Before attaching the Wing Coulter Chisel, prepare the tractor as follows:

1. Inflate the rear tractor tires equally and add ballast according to the tractor operator’s manual.
2. Lock the tractor drawbar in the center position.

Landoll 2131 Variable Ratio Adjustment
The leveler is equipped with a variable ratio adjustment. This is located at the rear of the hitch and at the center of the wheel lift where the leveler tube attaches. Connect the leveler tube to the top hole in the center lift and the bottom hole in the tongue for normal operation. This will cause the rear of the machine to raise higher than the front increasing transport height. The lower hole on the center lift provides an increased leveler ratio, which will cause the Coulter Chisel to become more level in transport. The lower hole should be used when a rear tow hitch is needed to reduce the height of the rear tow hitch during transport.
