Hello everyone, I've gotten into a little problem with my Murray 405000x8c. I was cutting the grass as usual and I hit a tree root that was under the grass. So, to make a long story short, it jerked everything really good, bent the mower deck, loosened a belt and more. After I had fixed those problems it started up, but when I put it into gear it wouldn't move. I'm figuring it's a spring that fell off, but when I look in the manual I'm not really sure what I need and can't pinpoint it. I have two riding mowers right now with issues... Any help would be great. Thank you !

Murray/Scotts 405000X8C

Might have thrown the drive belt off the engagement idler pulley or the transaxle pulley. It happens with worn belts and sudden stops.

Belts seemed to be ok, the belt under where the battery goes came off, and I put it back. How can I tell for sure about the things you've mentioned. Thanks !

Pull the deck off, et under the mower and grab the transmission belt
If al is connected properly if you push & pull the belt ( on each side ) you should be able to turn the engine over

Hey guys, I've finally got to the tranny belt and things went a lot smoother than I expected, except for just one thing. I put everything back the same way, or at least I thought I did, but when step on the brake to start the mower, it is extremely tight and the brake won't go down enough for me to start up the engine. I mean I can't understand what I did wrong. Do you guys have any suggestions on what I should do. Thank you !

Did you check the belt length old to new ?
Other than that the belt routing is probably wrong
Very easy to do this because it is not quite as obvious as it looks

Hi , yes the belt length is the same. I bought the original Murray 37x87 I'm not seeing how I routed the belt wrong though...

It is pretty straightforward. Get on the ground and watch, while someone moves the pedal.

I definitely will, thank you. I'll let you know how it goes

It is possible the OP put the belt on the wrong side of the idler pulley and now instead loosening the belt as he/she clutches they tighten it.

Maybe I did put it on the wrong side... Hopefully I'll get to it tomorrow and take a picture of it. It's such a simple belt layout, I don't see how I could screw that up. Maybe I had one too many when I did it, lol

Easily done
I can confess to doing it a few times myself
The trick is to get under and watch which way the tension pulley moves when you put your foot on the clutch / brake pedal
The pulley has to take pressure off the belt when the brake pedal is down

Lol,Thank you I'm working on it now

I took a shot at it again today and I'm really not seeing what I did wrong. The belt is not overly tight, it has some slack and everything else looks right to me, I mean all I did was take the old belt off and put a new one on, so this is definitely baffling me. I did forget to pull on both sides of the belt and start it, but I didn't have an extra set of hands though.

Okay is the side frames in following image label correctly? IF so you have the belt routed incorrectly because the belt is on the idler incorrectly. And this would explain the brake/clutch pedal depressing problem.

remove belt
loosen pulley
depress bake & lock pedal in park position
Run the other ( RH side ) of the belt through the pulley
The back of the belt runs against the pulley and the root of the belt goes towards the belt keeper tab

Hey guys, finally got a chance to reroute the belt, and just wanted to show you guys before I put the deck back. It's definitely a little trickier than how easy it looks in the manual. Thanks

My wife keeps telling me to take pictures before hand on removing parts, belts, etc. if not sure. I keep telling myself I can figure it out, until I can’t, then I waste time.

Lol, I hear you and I usually take pictures of everything before hand, but it looked so simple and I said to myself "I don't need any pictures of this" lol, now look.
