2.
The top center link typically is adjusted with the 
upper clevis pin vertically above lower hitch pins. as 
shown in Figure 3-3.
3.
With gloves on, carefully rotate each blade tip to the 
position shown in Figure 3-2.
4.
Measure distance from cutting tip of blade to ground 
surface. This distance is the cutting height.
5.
If desired cutting height cannot be obtained by 
adjusting the lower 3-point arms, then readjust 
tailwheel height. Se“Tailwheel Height 
Adjustment”
 on this page.
6.
Repeat steps 1 to 5 until desired cutting height is 
achieved.
7.
Set tractor’s 3-point hydraulic control stop at this 
height.
Center 3-Point Link Adjustment
Figure 3-3
Center 3-Point Link Adjustment
Refer to Figure 3-3: 
1.
Lower cutter deck to the nominal cutting height.
2.
Typically the center 3-point link is adjusted so that the 
upper 3-point clevis pin is straight above the lower 
3-point hitch pins. This arrangement allows for 
optimum ground contour following performance.
3.
Lock center link in this position once correct length is 
achieved. Adjustment on center 3-point link can be 
made depending on customer’s preference.
NOTE:  Customer may adjust center 3-point link to 
his or her preference. Lengthening center 3-point 
link allows more movement while going over raised 
surfaces. Shortening the link allows more movement 
while crossing over ditches. Also, shortening center 
link allows the cutter to be carried higher while 
traveling. Never length center link to where the 
cutter is carried too low.
Tailwheel Height Adjustment
Figure 3-4
Tailwheel Height Adjustment
Refer to Figure 3-4:
The deck slope should be adjusted so that the cutting 
blades are slightly lower at the front of the cutter than at 
the back. If they are not, the tailwheel must be adjusted 
up or down until the deck slope is correct.
1.
Make sure instructions for setting the “Cutting 
Height Adjustment”
 ha
ve been followed before 
continuing with adjusting tailwheel height below.
2.
Use tractor’s 3-point hydraulic control to lift tailwheel 
off the ground.
3.
Remove 3/8" carriage bolts (#1) and flange nuts (#2).
4.
Adjust tailwheel as follows:
To lower blade height at the rear, raise tailwheel.
To raise blade height at the rear, lower tailwheel. 
5.
With tailwheel adjusted to the correct position, 
replace 3/8" carriage bolts (#1) and whiz nuts (#2). 
Draw whiz nuts up snug, do not tighten until after 
rechecking deck cutting height.
6.
Recheck deck cutting height. Refer to instructions for 
adjusting the “Cutting Height Adjustment” on page 
15
.
7.
After the deck cutting height and tailwheel height are 
adjusted correctly, tighten whiz nuts (#2) shown in 
Figure 3-4 below to the correct torque.
