TINE TUBES AND TINES
Fig. 3: Lift arms and tine tube assembly – 4-Rank
Assemble tine tube and S-tines to lift arms as shown in Figure 3. Secure tube bushings in place with
four 7/16” X 1” bolts, lock washers and nuts. See Figure 5 for section sizes and Depth Chart (page
5-1) for vertical adjustment.
NOTE: There are two lengths of S-tine mounting tubes (except where noted). The long tubes (170”)
are used only on 15’ sections along with six lift arms. The short tubes (110”) are used only on 10’
sections with four lift arms.
Beginning at centerline of machine, space tines as shown in Figure 5. All measurements shown in
Figure 5 are to centerline of lift arms and tines. Tine tubes will have to be slid one way or the other
to get correct spacing. All S-tines are spaced 20” on center.
Fig. 4: Hydraulic cylinder lever location
When section tines are spaced and secured, install tube clamps to prevent tubes from moving side
to side. Install and secure connecting levers and links. Secure connecting levers with 1/2” u-bolts.
Secure connecting links with 1/2” X 2-1/2” bolts and lock nuts.
Refer to Figures 4 and 5 (pages 5-10-11) and position hydraulic cylinder levers and plates, secure
with four 5/8” X 4” bolts, lock washers and nuts.
IMPORTANT: S-tine mounting tubes and S-tines must not contact tires. To check clearance,
raise hinged wing support tires slowly to determine if tire contact will occur before travel limit
is reached. S-tine spacing may have to be adjusted to prevent interference.
