518-H

Recommended Posts

I have a 518 -H 

That won’t stop if I push the brake  in as hard as I can it almost stalls the engine  

question is when you push the brake pedal down does it put the hydraulic system in neutral or is the brakes supposed to fight the hydraulic system??

The brake is SUPPOSED to move the hydro to the neutral position. There may be some guidance in an owners manual.

Yes, my 516H being identical, the foot pedal returns the go lever to neutral - provided it's properly adjusted - and then begins to apply the brake. Your brake is also adjustable and likely worn. I had to replace the lining before it would engage at all.

Welcome to the forum  @skibum

 

Gonna guess that not only is the motion control not centering, the parking brake isn't working either.

 

Had the same issue with a 518-H. The likely problem is that the part of the brake linkage that activates the motion control centering and lets you apply the parking brake is disconnected. It might be as simple as a missing/rusted out cotter pin. Depending on your mechanical skills and dexterity, the fix is relatively straightforward. Access to that place is not.

 

I've annotated the IPL so you can see what's going on.

As noted above, there is no washer to protect the cotter pin and the pin itself was very small. I drilled a new hole in the end of brake rod #7 for the cotter pin--slightly larger and leaving room for a washer and a slightly larger pin. A pair of very long needle-nosed pliers (some strong forceps would have been better!) let me reach down in there to insert the pin. Once reassembled, I lubed the heck out of it with Red N Tacky grease.

 

Good luck and let us know how you fare!

Outstanding and you are most welcome! Now you can readjust the brake and you'll be good to go mowing.
