1026R - shuts down in reverse with blower engaged

[Jtschnel]

I bypassed the RIO on my 1025r. Makes it much better. Not sure if there is a write up on here but there are write ups on the net.

I did see a couple of methods where folks had bypassed, or effectively bypassed, the RIO. Not sure if it was here or GTT. One dealt with modification to the reverse switch under the deck. Another jumpered one of two pairs of connectors of the PTO dash switch. If all else fails I'll probably try the later=, but I'd much have it operate as its supposed to.

The service manager did stop at the house to take a look. Thanks to diagrams supplied by kennyd I was able to determine it does have the correct shaft assembly with the sensor. The service gent took a quick look at the wiring and it appears to be hooked up correctly. Since there is no adjustment to the sensor location, he's going to order another one. Hopefully, this will be all it takes.

kennyd, I'm assuming the serial number range you've given are the last 6 digits of the full number. If that assumption is correct, than I should be OK. The machines I have are 222913 and 222594 ... not sure which is which but both in the range you listed.

Will follow up when the new sensor comes in.

Thanks all.

There's no adjustment to the sensor location, but the gap spacing appeared quite sensitive to me. I spent a fair amount of time ensuring the gap I set was accurate - and the thing is hard to adjust assembled too.

I put it on app. 2 weeks ago, & mine works fine (can reverse w/o snowblower or engine cutting out).

Good luck!

any chance your raising up in the seat when pressing the reverse pedal and thus activating a safety switch. Had that happen on a ford mower i used to own because of the reverse pedal having too stiff of a spring .

At around 290 lbs, unfortunately no. ;-)

Can someone clarify how the Hall Effect sensor works? I thought the sensor detected changes in a magnetic field. So here was my train of thought.

For example, if a shaft had a magnet embedded in it and as it rotated past a sensor, the sensor would be able to detect changes as the magnet passed it. So being able to detect when the magnet passed and the time between passes, you could figure out rpm, or just the simple fact the shaft was turning.

If that's correct and there is no magnet embedded in the pto shaft (hard for me to get down there to look but I didn't see one), could the shaft at the sensor location area be magnetized with the shape of the shaft at that area (pentagon?) providing varying distance from tthe sensor as it turns. If the sensor "tripped" when a high point went past, the circuitry could tell when he shaft was turning.

Assuming any of my thoughts are valid, could it be possible that the shaft was an earlier version with no magnets or not magnetized?

Sorry about the wandering thoughts ... Late Friday after a long week, maybe a couple of beers shouldn't be mixed with problem solving ... :confused3:

Hall effect interrupts a beam of light. It's used for timing on some older Fords.

Sorry, that is 100% incorrect sir, see this link: Hall effect sensor - Wikipedia, the free encyclopedia

You are right and I learned something new today. Thanks. Now i wish I could remember way back to where I started thinking that.

This morning I used the 1026R with the rotary brush to clean a light dusting from last night. After becoming extremely frustrated the RIO disable function not working (replacement Hall Effect sensor not in yet), I decided to do the Jumper Method of bypassing the RIO function. I installed a switch under the hood similar to post #55 in the GTT forum thread. This link is a good resource for bypassing the RIO function:

I've got a Tektite cab on my 1026R which made access a real pain in the butt. A few scrapes, bruises and knots on my head, but got it done.

I'll disengage the jumper when they bring a front quick hitch replacement sensor in an attempt to get the RIO disable function to work, but now I'm ready for more snow!

I'll follow up when they replace the sensor and let you know if it fixes the original problem.

A bit of rewiring is in order here..
