Whether you have just noticed that your tractor has developed a problem when reversing or if it was slowly building up with time, I\u2019ll try to walk you through some troubleshooting and possible fixes of the issue in this article.<\/p>\n\n\n\n
You might find yourself in a situation where you attempt a backing-up maneuver with mower blades engaged, and your tractor just shuts off all of a sudden. That is just a sign that your RIO safety system is working correctly.<\/p>\n\n\n\n
RIO or reverse implement option is a safety system built into your tractor that insures riders’ attention when backing up with an engaged mower deck. <\/p>\n\n\n\n
It\u2019s extremely important for the rider to be as attentive and alert as possible when backing up the tractor with engaged PTO\u00a0 to insure the safety of little kids or animals that could be around. <\/p>\n\n\n\n
Backing up is a more dangerous maneuver as the visibility to the back is limited due to the rider\u2019s position and since the mower deck is placed closer to the back axle and tractor sides: the blind spot of the rider, it poses an additional danger.<\/p>\n\n\n\n
An RIO system is made up of an electrical circuit that includes the RIO key switch position, the RIO switch sensor, the PTO sensor, the reverse drive sensor, and the ignition cutoff electrical breaker.<\/p>\n\n\n\n
The job of the RIO system is to cut off the ignition or turn the engine off whenever the rider starts backing up with an engaged mower deck to insure the maximum safety of those around.<\/p>\n\n\n\n
However, you can execute the backing-up maneuver with engaged mower blades, you just have to let the system know that you are paying maximum attention and are fully engaged by moving your ignition key switch to the RIO position and holding it there until you have finished your backing-up motion.<\/p>\n\n\n\n
We will start from the easiest problem and move progressively to harder issues.<\/p>\n\n\n\n
First of all, as it\u2019s always a great idea to keep your equipment clean, take a brush and cleanse the whole linkage system that linked the pedal to the transmission and lies underneath the right foot-weld. Note if there isn\u2019t something stuck in the system.<\/p>\n\n\n\n
Also, check if some piece of debris hasn\u2019t stuck between the pedal itself and the body of your tractor.<\/p>\n\n\n\n
You should also inspect the integrity of the linkage itself.<\/p>\n\n\n\n
If your pedal has a limited range where you cannot engage forward or reverse mode to the full extent, your travel pedal linkage could be bent or deformed. In such a case, you should replace the linkage. <\/p>\n\n\n\n
In case only the revere mode range is limited, you should inspect the reverse pedal plastic boot integrity. Take a look if it hasn\u2019t fallen in. If so, inspect its integrity. Normally the boot shouldn’t be cracked or deformed in any way, and it should sit tightly on the metal pedal.<\/p>\n\n\n\n
If there is some sort of problem with your reverse boot, you should replace it. But a temporary solution can be implemented, you can fix its position with a bolt and a washer placed inside the boot’s square hole that would prevent the boot from slipping down the metal pedal rail.<\/p>\n\n\n\n
If you have found yourself in a situation where your tractor shuts off when you back up with the key in the RIO position, you have an RIO sensor problem.\u00a0<\/p>\n\n\n\n
In a vast majority of Husqvarna riding mowers, the RIO switch is implemented into the ignition key switch as an additional stage. It also usually plays the role of an RIO sensor. All in one, so to speak.<\/p>\n\n\n\n
To test it, take your ignition switch out and test the corresponding pair of contacts with an ohmmeter (for continuity), when the key is in the RIO position.<\/p>\n\n\n\n
First, let’s start with the easy problem. It can be a worn-out input shaft pulley that has worn-out splints. Typical symptoms are loss of power and immobility.<\/p>\n\n\n\n
As we\u2019ve established earlier, bad oil is the usual suspect with the vast majority of transmission problems.<\/p>\n\n\n\n
Bad oil can damage the drive shaft and input shaft seals which could cause oil leakage. The insufficient oil level will fail to provide adequate oil pressure inside the hydrostatic system, and it won\u2019t be able to transmit the energy. The typical symptom is winning, complete immobility, or severe loss of power.<\/p>\n\n\n\n
Differential and reduction gear-set gears as well as bearings can get damaged by excessive metal filling in the system. The process rapidly spirals as chipped pieces of gears cause even more destruction. Typical symptoms are insatiable mobility, slipping, and grinding noises.<\/p>\n\n\n\n
But the most common problem is, worn-out pump and motor pistons and their ports. Again, the premature wear of these is typically caused by bad oil that is full of metal fillings. The typical symptoms are loss of power, slipping, and whining noises; usually, the symptoms get worse as the transmission and the oil inside warm up.<\/p>\n\n\n\n
For detailed transmission troubleshooting, it first should be removed from the tractor and taken apart. Only then the differential, reduction gear set, center case, shaft seals, and bearings can be examined and changed.<\/p>\n","protected":false},"excerpt":{"rendered":"
