Snapper RE110 - Dies when Clutch is Released

#1

Good morning all,

I joined the forum to ask this question. I acquired a Snapper RE110 (28" 11.5 HP rear engine riding lawn mower - 7800950-00) in decent condition when I bought my home in late 2021. It needed a new carb because the old one was flooding so I replaced it and it had been working fine. Recently it started acting up again, it wouldn't crank at all. I found that when I pressed the clutch it was not depressing the switch near the rear axel so I adjusted the ferrules and the mower will now start up fine. However, it will die when I let off the clutch (in neutral or in gear) or try to engage the blades. I have already replaced the seat switch so it's not that. I think it may be the reverse switch, as I'm able to move the mower into reverse and when I let off the clutch it will die but then jerk backwards a tiny bit before completely shutting off. The reason I think it is the reverse switch is because the light is not coming on when I engage (turn) the switch.

Could someone confirm at what point that the reverse switch's light is supposed to come on or provide any other insight to this problem? Could it be that the clutch/brake switch needs replacing? If so, what do I need to do before flipping the mower on its back?


Also, the parking brake has never worked since I've owned this mower for 6mo if that's relevant.

Hey Mark - did you mean to link a particular site? That one is just a vague google search.

Are you sure it is electrical? Can the drive belt be easily removed so you can determine if load is killing it or electrical is killing it?

Thank you for the response! I haven't removed the drive belt but I'm not putting a load on it when I am in neutral and release the clutch pedal, so I would think it's electrical unless I'm misunderstanding something?

It will most likely be the seat switch

Dubya1886, See if you can locate your Operators Manual from above.

honestly i have 4 of those turtle mowers and 2 of them had endless kill switch issues, one would randomly shut off just when turning, and the other would just shut off when you hit a bump.

i cut the two purple wires coming from the key switch inside the harness under the seat next to the brake cables and then ran a new kill wire from them to the coil and that is the only way i got them running reliably right again.

it still wont start if blades are on, or if brake isnt pressed, and the seat kill switch still works, so i consider them completely safe from a safety switch standpoint

i love the turtle mowers but the electrical systems on them are complete junk and its the most common fault with them other then B&S made the rear axles weaker and prone to breaking

also, if you have the spring arm under the seat with the wheel on it, that is hooked to a cable that operates the deck spindle brake. if that cable came lose or broke, it wont want to let the deck spindle turn. its designed so the blades cant turn unless you are sitting on the seat so it chokes out the engine if its not pulled back to release the brake

this is really helpful, thank you. I plan to try this out - any chance you could send me some pictures of this mod?

first it only needs to be the one of those wires that goes to the kill wire for the magneto

i just seem to always pick the wrong one, so i just cut both to save time lol.

you are just eliminating the kill switch circuit on the mower and going straight from ignition switch to the magneto coil kill wire

raise the seat and look straight down from standing on right discharge side of the motor and you will see the purple wires there inside the wire loom

its still safe because the kill circuit to not let the starter solenoid work does the same job as the safety kill circuit so you are just eliminating one side of the safety circuit

damnit man you jinxed me, my dads turtle just did the same thing as yours was doing, no matter what you did, letting foot off the brake it just dies, whether in gear or not, blade on or off, it didnt matter. of 8 turtles i have owned, this makes 4 of them i had to bypass the safety kill switch circuits on.

so here is the fast and quick fix since its fresh in my mind.

remove battery, open wire harness loom by battery were it enters under seat after comes from the motor, find the purple wire and cut it as far you need to so you have enough room to work on it to connect a butt connector to it with a length of roughly 8" of black wire and add a butt connector on the end of that, then take the wire loom from key switch and locate the purple wire there and cut it in a spot you have room to smash the but connector on it and do that, then its done and tuck everything away as beast you can back in the wire looms and reconnect the battery. in short, you just connected the purple wire from key switch direct to the purple wire that goes to the magnito to kill the spark and eliminated the rest that went to all the safety kill switches on the mower.

your reverse switch and other kill switches will no longer work but the starting safeties still do, so it cannot start with the blade on, or the mower in gear, will still not allow the starter solenoid to work so its still safe as it needs to be in my opinion. key switch turned off is what kills the mower

hope this helps

it seems like they all do at some point. i dont like bypassing safeties but i never could resolve if it was the blade safety, deck safety, or rear axle safety or a combination of more then one that was the issue so i solved the problem my own way and it seems this is only an issue on the turtle mowers

Let's be fair keakar. Those junk mowers you speak of probably have mowed more grass than we've all seen. And of course have several decades of solid use on them. Little wiring repair for a 50 plus year old mower isn't out of line. "Come on guys!!! Brandon Biden"

Alright I got some butt connectors and wire, I just wanted to make sure I'm reading this correctly. Please see the image below and let me know if my interpretation of your writeup is correct. Thanks!

High quality image link.

sorry it took me so long to reply, i have been busy

there is a purple wire in the loom that goes out the hole towards the engine

all you need to do is cut that purple wire right around where the small red battery wire goes into the harness by that white plug and splice a new wire onto it and just leave the rest of the purple wire in the loom that goes into the main loom disconnected, it is harmless and will no longer connected to anything.

now grab the loom coming from the key switch and find the purple wire in it, cut that purple wire and splice the other end of the new wire you added to the one going to the engine (leave the rest of purple wire in the loom that goes into the main loom disconnected)

so you now have a direct purple wire from key switch running to the engines purple wire pretty much the way you drew that yellow line to show

you dont want to unplug or disconnect anything else but just those two purple wires

and thats it, you bypassed the ground side of the safety kill circuit so you no longer have those safeties

there are still going to to be ground safeties that disable the starter solenoid so it wont start unless foot is on the brake

and the blades are not engaged so its still safe, just not as safe as it was from the factory

in its simplest way to explain it, you ran a direct kill switch connecting the purple wire from key switch directly to the purple wire to the engine
so they are no longer connected to anything else but each other
