How to Disable Reverse Implement Option RIO on 2012 John Deere 1 Series SCUTs 1026R 1023EBy
CAUTION: Disabling any feature that is intended as a safety device can subject the operator of the modified equipment and those in the immediate vicinity to an increased risk of injury or death. Please use your own best judgment when performing any safety modification to your equipment. Note: The photos shown here are of a John Deere 1026R with a serial number beyond 210000.
You will need the following tools:
- 10mm open end wrench
- Socket wrench
- 8mm socket
- 10mm socket
- Small allen wrench
- #3 Phillips head screwdriver (#2 will work as well)
Remove the lower kick panel from the operator’s station
- Remove the deck height adjustment knob by pulling straight up on the knob. It is friction fit; there is no set screw.
- For 1026Rs, loosen the set screw on the rate of drop dial using an allen wrench and slide the knob off of the adjustment rod.
- Remove the 10mm bolt and washer from both sides of the operator station kick panel. These are the top bolts located just below the seat on both sides. Be careful not to lose the metal spacers. When you pull the bolt out it should be sitting in the well where the bolt was just removed.
- Remove #3 phillips head screws and washers from the bottom portion of the kick panel. You’ll find these in the recessed holes on both sides of the operator’s station.
- At this point you should be able to wiggle the kick panel free. Note that the top of the panel is tabbed and rests underneath the plastic panels on each side of the operator’s seat. The middle of the kick panel rest underneath the seat mounting platform. Set the panel aside.
- Optional: Take a moment to note just how dirty your machine gets in the places you cant normally see or get too.
The Reverse Sensing Switch (RSS)
In the photos below, you’ll see the switch that lets the control circuits of the tractor understand when the reverse pedal has been pressed. The lever action is such that when neither pedal is being pressed, the RSS is depressed. When the forward pedal is pressed, the RSS is depressed. When the reverse pedal is pressed, the RSS is released and the switch is deactivated. I used a circuit tracer (hey, use what you got ) to run some traces on the contacts. This demonstrated to me that the two left terminals (from referencing the third photo below) are normally connected to complete a circuit. When the switch is depressed these terminals are opened and the two right terminals are closed completing a circuit. It is also worth noting that if you disconnect the switch and switch the ignition to START, the LCD will display REVERSE SENSOR ERROR. The tractor knows to look for that switch during POST!
How to override the RSS
In theory, you could just jumper the two mating terminals on the right (from reference in photo above and the red and blue wires in the second photo below) and call it a day. However, I wanted to be able to leave everything connected and make the switch stay depressed. Here is where you can get creative. Below is what I did to accomplish the task.
I had an old piece of angled aluminum from an old garage door sensor mount. I modified it by cutting off the excess and drilling two mount holes that matched the dimensions of the screws used to mount the RSS to the bracket. The screws are 8mm with 10mm nuts. Once everything was mounted back up, the angled bracket kept the switch depressed.
I jumped up on the seat, started the tractor, activated the mid-PTO, and pressed the reverse pedal. SUCCESS, the mower stayed running!
After a little more testing, I put the kick panel back on in the same manner in which it was removed. Looks factory original, and all I have to do to enable the “safety feature” of the RSS is remove my angled bracket.
I’d like to thank an anonymous contributor that helped point me in the right direction to look for this switch. PLEASE, be careful anytime you are using your tractors and be aware that disabling any safety feature puts the responsibility on you to perform in its stead.
