Attaching Mower-Conditioner

1. Carry out following procedure for attaching mower-conditioner properly.

Attaching to Three-Point Hitch:

The mower-conditioner can be attached to any tractor with a three-point hitch conforming to category II or III. See your John Deere dealer to adapt the features of your tractor to those offered by the machine.

a. Reverse tractor until hitch points are approximately in line.

b. Attach the draft links to the lower hitch pins (A) and secure with quick-lock pins (B) if necessary.

IMPORTANT: Make sure jackstand (C) stays on the ground.

c. With both jackstands (C) on the ground, attach the center link (F) to the upper hitch point (D) so that with machine fully raised, the main gear case input shaft is parallel to the ground then secure with quick-lock pin (E) if necessary.

NOTE: Adjust length of center link (F) to carry out this adjustment.

2. Setting Machine Frame to Correct Operating Height:

For field operation and road transport, the machine frame requires to be set to a certain distance from the ground.

a. For Transport Position: Set position control so that lower hitch pins (A) are at a distance (B) of 500 mm (19.68 in.) from the ground.

b. For Working Position: Set position control so that lower hitch pins (A) are at a distance (B) of 600 mm (23.62 in.) from the ground.

IMPORTANT: Depending on tractor type with the 388 mower-conditioner in transport position, it may be required to set the machine frame below 500 mm (19.68 in.) to maintain the 4 m (13 ft 1.44 in.) road transport height limit.

NOTE: Refer to the tractor basic Operator's Manual to set hitch height correctly.

4. Connecting Load Sensing Hose to Tractor With Load Sensing Port or Power Beyond Module:

Connect Load Sensing hose (A) to the Load Sensing port or to the Power Beyond port of the tractor (if equipped).

Make sure that connector (B) is connected to the Load Sensing valve (C) on the mower-conditioner hydraulic block (D).

If this is not the case, it means that the mower-conditioner has previously been attached to

a tractor without Load Sensing. In this case, the mower-conditioner hydraulic block MUST be configured for Load Sensing connection. Proceed as follows:

1. Disconnect connector (B) from the by-pass valve (E) and connect it to the Load Sensing valve (C).
2. Turn red screw (F) on by-pass valve (E) fully clockwise.
3. Measure and record length (X) of adjusting screw (G) on relief valve (H).

4. Unscrew lock nut then turn adjusting screw (G) fully clockwise.

causym CAUTION: Maximum working pressure of the mower-conditioner hydraulic hoses is about 20000 kPa (200 bar; 2900 psi).

IMPORTANT: Do not attempt to connect the hydraulic hoses of a machine configured for Load Sensing in the same way as those of a machine not configured for Load Sensing.

The distance (X) corresponds to a relief pressure setting of 20000 kPa (200 bar; 2900 psi). Do not use the machine with the adjusting screw (G) set to a different length.

5. Connecting Load Sensing Hose to Tractor Without Load Sensing Port or Power Beyond Module:

DO NOT connect Load Sensing hose (A). Keep it plugged on its storage support.

Make sure that connector (B) is connected to the by-pass valve (C) on the mower-conditioner hydraulic block (D).

If this is not the case, it means that the mower-conditioner has previously been attached to

a tractor with Load Sensing. In this case, the mower-conditioner hydraulic block MUST NOT be configured for Load Sensing connection. Proceed as follows:

1. Disconnect connector (B) from the Load Sensing valve (E) and connect it to the by-pass valve (C).
2. Turn red screw (F) on by-pass valve (C) fully counter-clockwise.
3. Set adjusting screw (G) on relief valve (H) to specified dimension.

IMPORTANT: Do not attempt to connect the hydraulic hoses of a machine not

configured for Load Sensing in the same way as those of a machine configured for Load Sensing.

6. Connecting Hydraulic Hoses to the Front Mower-Conditioner:

Two additional hydraulic hoses are provided for the front mower-conditioner. The front mower-conditioner is controlled by the control monitor (see "Operating Control Monitor" Section) and must be connected as follows:

  • To control raise and lower of the front mower-conditioner, use the upper coupler (A).
  • To control floating of the front mower-conditioner, use the lower coupler (B).

7. Tractor Electrical Connections:

IMPORTANT: All electrical equipment installed on the mower-conditioner is designed for use on 12 Volt electrical systems with negative ground.

Attach warning light plug to tractor (if not equipped, RE17282 kit for 7-terminal auxiliary outlet is required on tractor).

Connect machine wiring harness connector (A) to the control monitor (B).

8. Adjusting Telescoping Hook-Up:

Make sure telescoping hook-up length is correct.

  • When the telescoping hook-up is in its maximum extended position, a minimum tube overlap of 250 mm (10 in.) must be maintained.
  • When the telescoping hook-up is in its maximum overlap position (retracted), tubes should not butt against the yokes. As a safety measure a clearance of at least 10 mm (0.4 in.) must be maintained.

If this is not the case, reduce length of both half drive lines (A) and their relevant shaft guards (B) by the same amount.

IMPORTANT: Never operate telescoping hook-up at too great an angle (30 degrees maximum).

NOTE: Once cut, round off all sharp edges and remove burrs, particularly on the inner face of the outer hook-up half. Lubricate inside of outer hook-up half.

9. Connecting Telescoping Hook-Up:

causym CAUTION: Never attach telescoping hook-up while the tractor is running. Never use a steel hammer to connect or disconnect the hook-up on PTO shaft.

IMPORTANT: Keep hook-up and PTO shaft splines free from paint, dirt, chaff and burrs.

  • Make sure that telescoping members are assembled so that joint planes are in proper position as shown.
  • Refer to the basic telescoping hook-up Operator's Manual to properly connect telescoping hook-up to the tractor PTO shaft.
  • Make sure hook-up is firmly latched to tractor PTO shaft.
  • Reinstall all shields, if removed.
  • Secure telescoping hook-up shield by hooking safety chain to any tractor/machine anchor.

10. Attaching Transport Latch Rope:

causym CAUTION: Avoid personal injury and/or machine damage. Do not attach rope to operator's seat or other locations that could cause snagging. This could result in the machine position changing.

Attach the transport latch rope (A) to a convenient location near tractor centerline. This will reduce the possibility of tractor tires snagging the rope.
