Assembly Instructions for the Rolling Harrow and Reel



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

Mount the rear stand bracket [(71) 580-049H], if applicable, to the drag frame with 5/8x4x4 ¼

U-bolts, a lock washer and a nut as shown on figure 1. The rear stand leg [(70) 560-196H] should be
pinned in the rear stand bracket with a 3/4x4 ½ pin and retainer (805-081C).

Mount the reel arm assemblies (589-069L) to the drag frames, using the dimensions in figures 6-

10, using a 5/8x3x4 ½ U-bolt [(44) 806-183C] with a lock washer and nut. These bolts may be
tightened at this time. Assemble the reel sub-assemblies to the reel tube by U-bolting the reel brackets
to the correct tube with a 5/8x2 1/2x3 ¾ U-bolt [(16) UB0037], lock washer, and nut. See bottom of
page for correct reel assemblies. If you are assembling a 10’ or 12’ reel, do not install the two center U-
bolts as you will use 5/8x4 hex bolts (802-060C) with lock washers and nuts in this location as shown in
figure 5. Once the reels are attached to the reel bar, bolt the reel bar to the reel arm assemblies using the
dimensions in figures 1, 2, and 3. If you are bolting on a 10’ or 12’ section; by using the 5/8x4 bolts as
shown in figure 5 the reel will be in the proper location. If the reels between the center section and the
wing sections are closer than 4”, recheck the reel arm dimensions.
