How do you replace a brake cable on a Husqvarna rider 155

Did you disengage the brake. I sometimes forget to disengage the brake but when the engine starts to shut off i realize that I did not disengage the brake.

Depends on what model this is, if it is a centre rear discharge machine then either the collector bag is not on correctly ( micro switch is in the back panel and operated by a lever when the bag is connected) or the seat switch is not connected or faulty ( micro switch under the seat pan,

Most riding mowers have a kill switch wired to the seat. It kills the engine if the rider falls off or gets off the seat. Check to make sure this switch is not shorted or faulty. Replace if necessary.
Hope this helps.

I think it is in hex ( 494841 ) or (444 33d)in hexadecimal

take a look at the safety switch on the clutch/brake pedal jump it with a paper clip to test it

here are the manual for the rider 820-8

clean it down with engine degreaser and run it check for leaks again

did the drive belt come off

I would guess that you have a bad front brake light switch. The switch in located in the right handlebar switch housing. To get to it, you'll have to loosen the adjusters on your throttle and idle cables. Then take out the two screws holding the switch housing halves together. Disconnect the throttle and idle cables from the throttle sleeve and carefully separate the two switch housing halves. The brake light switch is the small switch located in the front of the housing. You will have to de-solder the wires from the switch, replace the old switch with a new one by removing the screw that holds the switch in place, then re-solder the wires to the new switch.

Lubricate the handlebar and the inside of the throttle sleeve with some thin grease and install it back into the lower switch half. Reconnect the throttle and idle cables and carefully reassemble the two switch housing halves being very careful not to pinch any wires. Slide the throttle assemble all the way up against the front brake master cylinder. Readjust the two cables leaving just a bit of slack in each one. Turn the throttle wide open and let it go. The throttle should "snap" shut. If not, readjust the position of the throttle assembly on the handlebars and the cable adjustment until it does.

Good Luck

Not an expert but have a rider 155. After looking at diagram on partstree.com, it does not appear to have a filter. Just a magnetic drain plug. This is the only site I have found for info and parts.
