Can't pull choke knob up on my riding lawn mower

All of a sudden, can't pull the knob up to engage the choke. It is like the wire inside the cable is fused. I have removed it from the mower and neither end, (the knob or the wire end that connects to the carborator) moves freely inside the outer cable. The arm that connects the cable to the carborator moves fine. Should the wire move freely inside the cable, thus allowing the knob to be pulled up engaging the choke? The mower is a Murray Ultra 46" cut 46403x8a with a Briggs & Stratton engine...Murray was baought by Briggs...

Take the cable off the mower and clean it in a pan with solvent or brake cleaner spray. you can coil it up to fit the pan while soaking. afterwards, let dry --- if you have an air compressor blow it dry to help clean and dry it --- then oil it up with a light oil or wd-40, wipe it off, stretch it out, and work the cable again before you remont it. the cable will stick if it gets too dirty and has no lubrication. may want to buy a new cable but they usually can be cleaned and lubricated.

    yes, the cable should move freely --- especially off the mower and laid out straight. after it is remounted there will be some resistance from curving the cable, but both resistance and curving should not be affecting operation of the choke.

How do you remove the choke assembly from the handle of the choke on the mower body i have disconnected it from the throttle

The Choke handle/knob is fastened to the dash of a riding mower either with a clip behind the dash or a nut and washer around the assembly. The clip can be removed with needle nosed pliers . The nut can be removed with a wrench that fits the nut and holding the cable with pliers as a back up. After this the cable will come out thru the dash.

What causes fuse to blow every time I try to engage blades?

To engage the blades is it a knob to an electric switch that you pull?
If so does the wire from the switch activate a electric clutch?
Is the wire damaged and shorted to the frame, is the clutch shorted. If you provide the brand name and model number I might be able to find a schematic for your mower.

Video shows an electric clutch but yours may be different but this should give you an idea of where to look. Riding Mower Electric PTO Clutch Won Engage When Hot Problem Fix

Belt. came off... pulling up blade engagement knob nothing seems to happen.....I have trackter up on blocks with blade cutting height at 1 with engine runnig the blade engagement knob switch ...

sounds like a bad PTO, that is the electrical gizmo on the bottom of the engine's driveshaft which engages the bottom pulley, running the deck. you might luck out and find the fuse is blown so follow the wire from the PTO back until you find the fat part in the wire. the fat part is an in line fuse holder with a fuse in it. if the fuse is bad and blows again, you need a new PTO

How do you start it?

what kind of mower is it?
For any mower you need to check that you have proper oil level, and that there is gas in the tank. If it is a riding mower there are a few things to know before you start. There are safety interlocks that have to be complied with before a start is permitted. The blades must not be engaged. Someone must be in the seat, and the brake must be fully engaged. Move the throttle to choke for starting (or pull the cable out if that be the case), start mower. Return choke to normal operating position.
For a push mower check your oil and fuel. Prime the carb. if necessary, push the button by the carb. until you are pushing fuel and then a couple more times. If it has a throttle cable put in choke position. Pull back on the safety bar. Pull cord to start. Throttle cable to normal running position, generally full throttle right before you start to engage the choke.

I hope this helps, if any questions just reply. Be sure you let me know what you did and what kind of machine it is.

If this is really helpful, please rate.

Lawn mower stays running on jumper cables but once disconnected it shuts down when choke is engaged

if it is already running and you "engage" the choke, you will flood the engine with too much gas and it will sputter and die. the only time you engage the choke is to start the engine when it is cold. if the mower dies when you remove jumper cables, and you leave the choke alone, you need to have someone look at your charging system.

When engaging mower blades speed drops or stops

Check throttle cable at carb and make sure you have full travel. Sounds like rpm is little to low. Throttle cables are usually held in place with 1 screw and a washer. Put cable at full throttle loosen screwand pull back until throttle at carb in at full then tighten screw.
