PRE-STARTING CHECKS

Do the following each day before start-up:

CAUTION:

1. Clear the area of other persons, pets etc. Keep children away from machinery. Walk around the windrower to be sure no one is under, on or close to it.

2. Remove foreign objects f rom the machine and surrounding area.

3. Wear close fitting clothing and protective shoes with slip resistant soles.

As well, carry with you any protective clothing and personal safety dev ices that COULD be necessary through the day. Don’t take chances.

You may need:

- a hard hat

- protective glasses or goggles

- heavy gloves

- respirator or filter mask

- wet weather gear.

4. Protect against noise. Wear a suitable hearing protective device such as ear muffs or ear plugs to protect against objectionable or uncomfortable loud noises.

5. Check t he machine for leaks or any parts that are missing, broken, or not working correctly.

NOTE: Use proper procedure when searching for pressurized fluid leaks. See "Hydraulics" in Maintenance/Service section.

6. Be sure tractor and windrower are properl y attached, all controls are in neutral and tractor brake is engaged.

7. Clean all lights and reflective surfaces on the machine. Check lights for proper operation.

8. Perform all Daily maintenance. See Maintenance/Service section.

OPERATION

OPERATE CORRECTLY

CAUTION:

1. Follow all safety and operational instructions given in your tractor Operator’ s Manual. If you do not have a tractor manual, get one from your dealer and read it thoroughly.

2. Never attempt to start the tractor engine or operate the windrower except from the tractor seat.

3. Check the operation of all controls in a safe clear area before starting work.

4. Do not allow riders on tractor or windrower.

5. Never start or move the machine until you are sure all bystanders have cleared the area.

6. Avoid travelling over loose fill, rocks, ditches or holes.

7. Drive slowly through gates and doorways.

8. If cutting ditch banks, use extreme caution. If the windrower hits an obstruction, the front of the tractor will usually swerve towards the ditch.

9. When working on inclines, travel uphill or downhill when possible. Be sure to keep tractor transmission in gear when travelling downhill.

10. Never attempt to get on or off a moving tractor.

11. Do not get off the tractor while the windrower is in operation.

12. Stop tractor engine and remove key before adjusting or removing plugged material from the

machine. A child or even a pet could engage the drive.

13. Check for excessive vibration and unusual noises. If there is any indication of trouble, shut down

and inspect the machine. Follow proper shutdown procedure:

- engage tractor brake

- disengage PTO

- turn off engine and remove key

- wait for all movement to stop

- dismount and engage cylinder stops before inspecting raised machine.

14. Operate only in daylight or good artificial light.

ENGAGING THE P TO

DANGER: Be sure all bystanders are clear of the machine before engaging the PTO. Never leave tractor seat with the PTO engaged.

• Engage the PTO slowly, just before the windrower is moved up to the standing crop.

• Be sure tractor PTO is running at correct rpm before starting to cut. (540 or 1000, as equipped.)

• Disengage the PTO when not operating the windrower.

OPERATION

LIFT CYLINDER STOP (RAISING AND LOWERING WINDROWER)

WARNING: To avoid bodily inju ry or death from fall of raised machine, always engage lift cylinder stops before going under windrower for any reason.

To engage cylinder stops:

1. Raise machine to maximum height by activating remote cylinder control valve in tractor. NOTE: Hoses should be connected so that moving control lever (A) back header.

2. Remove cylinder stops from storage pos ition and install in engaged position (B). Secure with clevis pin and hair pin.

3. Lower machine slightly so stops take some weight.

To lower windrower:

1. Raise machine to maximum height to take weight off stops.

2. Remove stops from cylinders and store in position (C). Secure with clevis pin and hair pin.

3. Lower m achine by activating remote cylinder control valve in tractor.

OPERATION

STEERING

Steering the windrower is controlled by the tractor remote hydraulic system. This steering system allows the windrower to follow directly behind the tractor, make a full cut to either side, or any position in between. NOTE: To allow hitch to swing, latch rod must be in field position (D). If rod is in transport position (A), pivot rod retainer (C) up to allow moving rod from (A) to (D).

NOTE: Hoses should be connected so that moving tractor control lever (E) forward steers the machine to the right and moving the lever back steer s the windrower left.

The control is operated m omentarily for steering and must be returned to OFF or NEUTRAL position as soon as the windrower reaches the desired path of travel.

The center pivot provides the operator the opportunity to move the windrower into field position easily, allows right angle turns in either direction, steering around obj ects on both sides and straight line field cutting on either side of the tractor. NOTE: Before steering the windrower, the header should be raised enough that the skid shoes clear the ground.

180q TURN

When cutting back and forth on one side of the field, approximately 50 ft. (15 m) is required at each end of the field to make a 180

Proceed as follows:

1. Beginning at position (A), the tractor is guided away from the uncut crop while the windrower is guided straight ahead until cutting through the end.

2. As soon as the sickle cuts through, raise the header to lift the skid shoes clear of the ground, and steer the windrower to the extreme direction away from the uncut crop.

NOTE: For ease of operation, both lever s can be ac tivated with one hand and held until steering cylinder completes its stroke.

3. At position (B), start turning the tractor back towards the uncut crop.

IMPORTANT: When turning, take care that the inside tractor tire does not contact tongue of windrower.

4. In positions (C) and (D), continue turning towards the uncut crop, (with the windrower steered towards the outside of the turning circle), being aware of tongue-to-tire clearance.

5. At position (E), the tractor com pletes the cir cle and the front wheels are turned to s traddle the last cut windrow. At this point, steer the windrower to line up with the edge of the uncut crop.

6. At position (F), lower header to cutting height and begin a new cut through the field.
