HARVEST TEC 477 John Deere Self-Propelled Forage Windrowers Owner’s Manual

HARVEST TEC 477 John Deere Self-Propelled Forage Windrowers

The Harvest Tec model 477 Acre Meter is designed to be installed on John Deere model 4890, 4895, 4990, and 4995 self-propelled wind rowers. The meter will monitor the Rate of cutting in Acres/Hr Acres cut by: field, last field, day, yesterday, and season. The 477 will take signals off of the wind rower for speed based on the tachometer input sensor located on the right-hand drive wheel of the windrower. With accurate input by the operator for the width of cut and tire size, the 477 will calculate the acre values listed. The sensor wire plug located by the brake disc will be tapped to provide the speed input. The meter will be activated, only when the head is engaged and in the down position. The meter will be de-activated when the head is lifted so that running time in the non-cutting mode will not be counted. Lifting the head a small amount for operation in rough fields will not deactivate the meter. Signal input for head engages and head raise and lower are all tapped at the plug linking armrest functions to machine devices, located at the back of the cab. Follow these instructions for setup and operation to assure proper function of the 477 meters.

INSTALLATION INSTRUCTIONS

1. Locate the meter in the cab, directly above the interior rearview mirror as pictured in figure 1. Note that the fit is tight against the cab’s ceiling so it is important to position the meter correctly. Hold the meter in place and mark the position for a 3/8” hole to accept the meter’s mounting stud. To drill the hole, remove the headliner and unbolt the mirror bracket for drilling. Bolt the meter in place with the 5/16” nuts provided.
2. Open the electrical panel access door on the front right side of the engine compartment. The meter harness will tap power and signals for head engage, raise and lower at this point. Drill a 1 1/4” hole in the back of the cab wall to run the harness to the meter. Use the 1 1/4” grommet provided to seal the hole into the cab and protect the harness.
3. Run the harness connection with the 9-pin round connector to the back of the meter. Secure the wire on the right cab post with the padded clips provided.
4. Connect the positive and negative power leads to the power terminals of the windrower. In the electrical access panel, the positive terminals are under a blackguard. The positive wire (red) should be connected to the top terminal so that the meter will power up with the ignition switch. The negative wire (black) should be grounded to the grounding terminal just below it.

1. Disconnect the 14-pin round connector coming from the armrest into the electrical panel. Connect the meters 14-pin connector between the male and female connector of the machine. Make sure all connections are tight.
2. Run the remaining lead to the speed sensor by the machine’s right-hand brake disc located right inside the right drive wheel. There is a wire disconnect attached to the speed sensor. Disconnect the wire and plug in the male and female connections on the meters harness. Make sure to use the tie wraps provided to keep this wiring assembly away from all moving parts.
3. The meter is now ready to use. Follow the start-up check procedure below to assure that installation has been completed successfully:

• Power the windrower up and check the screen display. It should display:
• Engage the head.
• Lower the head and move forward. The screen should come up with a rate in acres per hour.
• Raise the head and the screen should again display “RATE” ???

If this check-out procedure is okay, the meter is now ready for setup and use.

SET-UP INSTRUCTIONS:

Setting the cutting width

• PUSH THE SELECT KEY ONCE
• The display will read the set cut width

USE THE LEFT AND RIGHT ARROW KEYS TO SET YOUR CUTTING WIDTH.

Setting the tire size

• PUSH THE SELECT KEY ONE MORE TIME
• The screen will read the set tire radius

USE THE LEFT AND RIGHT ARROW KEYS TO SET THE RADIUS OF YOUR TIRE.

To determine the radius of the tire on your wind rower, follow these steps

1. Make sure that your tire is properly inflated. Make a mark on the tire and a corresponding mark on the ground lining up with the mark on the tire. Drive the windrower forward until the mark on the tire has completed one rotation (this should be done over a surface similar to a hay field). Make another mark on the ground lining up with the mark on the tire. Measure the distance between the marks.
2. Divide this distance by 6.28 and enter this as the tire size value.
3. For model 4895 after serial number E04895X 164201
4. Model 4990 after serial number E004990X 163101
5. Adjust the tire radius according to the following table

TIRE RADIUS/ ENTER

• 22 21
• 23 22
• 24 23
• 25 23
• 26 24
• 27 25
• 28 26
• 29 27
• 30 28
• 31 29
• 32 30

AFTER THE CORRECT CUTTING WIDTH AND TIRE SIZE HAVE BEEN ENTERED, THE 477 METER IS READY TO USE.

Common questions about the 477

The meter does not go back to “??” when the head is raised

The 477-acre meter is designed to start counting when it sees a signal that the head has been lowered. The meter will not stop counting or display “??” until it sees an up signal for more than three seconds or three to four bumps of the head-up switch. This is a common occurrence at the end of the field when turning around. Raising the head fully should correct this problem.

Meter does not go back to “??” when not moving forward

The 477-acre meter uses the same magnetic speed sensor that is used on the machine to calculate acres. This sensor is located on the right-hand wheel of the machine. The sensor works by counting the revolution of the wheel through holes in the brake disc. If the machine stops and the sensor is half on or half of one of the holes, it may still give a signal. Make sure the sensor is securely fastened to the machine. Raising the head all the way or disengaging the head when not moving will correct the problem.

The unit loses all inputs or memory or locks up

If the 477-acre meter has an extreme power spike, (i.e. jump start, short in power, overcharging of battery) it can cause the meter to reset itself. Keep track of the conditions that cause this failure. If this becomes a common occurrence your meter may need to be serviced.
