Section 1: Assembly and Set-up

Driveline Minimum Length

Refer to Figure 1-4:

1.Start tractor and slowly engage 3-point controls to move lower arms until the gearbox shaft is approximately level with the tractor's PTO shaft.

2.Slide inner yoke of driveline over the gearbox shaft and secure with locking collar.

3.Slide outer yoke of driveline over the tractor PTO shaft and secure with locking collar. Skip to "Driveline Maximum Allowable Length" if driveline fits.

4.The driveline will require shortening if it does not fit between tractor and mower. Shorten driveline as follows:

a.Raise or lower 3-point lower arms until mower and tractor PTO shafts are approximately level with each other. Securely block Flail Mower frame in this position.

b.Set tractor in park, shut tractor engine off, set park brake and remove switch key.

c.Pull driveline apart into two sections as shown in Figure 1-4. Attach outer driveline universal joint to the tractor PTO shaft. Attach inner driveline universal joint to the gearbox shaft. Pull on each driveline section to be sure universal joints are secured to the shafts.

d.Hold driveline sections parallel to each other to determine if they are too long. The inner and outer shields on each section should end approximately 1" short of reaching the universal joint shield on the adjacent section (see “B” dimension). If they are too long, measure 1" (“B” dimension) back from the universal joint shield and make a mark at this location on the inner and outer driveline shields.

e.Cut off inner shield at mark (“X” dimension). Cut same amount off inner shaft (“X1” dimension). Repeat cut off procedure (“Y” & “Y1” dimensions) to cut outer driveline half.

f.Remove all burrs and cuttings.

Driveline Maximum Allowable Length

Be sure to check driveline minimum length before checking driveline maximum allowable length.

Refer to Figure 1-5:

Driveline maximum allowable +length, when fully extended, must have a minimum overlap of profile tubes by not less than 1/3 the free length with both inner and outer profile tubes being of equal length.

Driveline Maximum Length

Figure 1-5

1.Measure and record driveline free length.

2.Apply multi-purpose grease to the inside of the outer driveline profile and reassemble the two profiles.

3.Move driveline halves together until profile tubes overlap by 1/3 the free length. Measure and record maximum allowable length shown in Figure 1-5.

4.Attach inner driveline yoke to gearbox shaft and outer driveline yoke to tractor's PTO shaft.

5.The driveline should now be moved back and forth to insure that both ends are secured to the PTO shafts. Reattach any end that is loose.

IMPORTANT: The two supplied safety chains must be attached to outer and inner driveline yoke shields and to the mower deck and tractor to keep driveline shields from rotating.

6.Hook one driveline safety chain in the hole on the outer driveline yoke shield and the opposite end to the tractor.

7.Hook the second driveline safety chain in the hole on the inner driveline yoke shield and the opposite end to the mower.

8.Start tractor and raise Flail Mower just enough to remove support blocks used in step 4a.

9.Slowly engage tractor’s 3-point controls to lower mower. Check for sufficient drawbar clearance. Move drawbar ahead, aside or remove if required.

10.Raise and lower implement to find the maximum possible extended driveline length. Check to make certain that the driveline has not extended beyond the maximum allowable length recorded in step 3 of this section.
