Assembly Instructions for the Rolling Harrow
Your initial action is to locate the correct drag frame [(61) 589-107H through 589-116H]. Bolt
the drag frame to the rear drag plates located on the rear of your Great Plains Turbo Till, using 5/8x1 ½
hex bolts [(43) 802-051C] with 5/8” hex nuts [(25) 803-021C] and 5/8” lock washers [(26) 804-022C].
The rolling harrow gangs shown in figure 4 will come to you partially assembled. To finish assembly,
refer to the table in figure 4 and assemble accordingly. Start by locating the correct rolling harrow tube,
center it over your partial assembly on the bearing hangers [(52) 589-142H], and mount the tube using
5/8x3x4 ½ U-bolts [(44) 806-183C] with a lock washer and nut. Your next step is to locate the ball joint
assemblies [(59) 589-064H]. Figure 4 shows you the dimensions to mount the ball joint assemblies on
the rolling harrow tube. Count the number of each assembly in figures 1-3 and assemble accordingly.
Mount the rolling harrow brackets [(60) 589-057H] to the under side of the drag frames
according to the dimensions in figures 1-3, using a 5/8x3x4 ½ U-bolt [(44) 806-183C] with a lock
washer and nut. You may tighten the U-bolts on all the brackets that are closest to the rear of the
machine. Leave the front brackets loose to slide until the rolling harrow assemblies are hung under the
frame. Use the 1x4 hex bolt and 1” nylock nut through the harrow brackets (589-057H) and ball joint
assemblies [(59) 589-064H] to hang the rolling harrow assemblies under the frame. Be careful to put the
proper gang in the proper location and be sure that the assemblies are oriented correctly as shown in
figure 4. When all gangs are hung under the frame, tighten the remaining U-bolts.
