How to remove starter on Toro Z master with kohler 26 HP engine?

Check voltage at battery is >12.0VDC. Try jumpstart. Check battery cables and engine ground bond.

The B&S Vangaurd engine requires periodic valve lash adjustment (100 hrs by schedule). Overdue valve lash adjustment typically manifests with starter stall (starter engages, rotates engine, hesitates or stalls, and then spins/starts).

The keys are not dropping in the clutch fan. Lightly tap with hammer before attempting to start. Will need to replace eventually.

check to see if pto will engage if not check voltage at pto if non blown fuse if fuse not blown and power to pto bad pto jump the pto at pto with battery in mower does it start pto if does good pto have to check volts at switch check there start with that let me no what happened

OC is over crank failed to start. It will normally try 3 times before giving this error. You need to disconnect the battery and remove the starter motor, make sure it is free to move / spin. Either the starter has seized or the engine has siezed. Make sure the engine is free to rotate also, once you remove the starter you will see the engine flywheel there, removing the spark plugs will make it easier to rotate the engine. I would guess it is more the starter.

I think this is going to be like an automotive starter.
You will need to check 3 things.
The ring gear where the starter gear cranks the engine, the starter gear that engages the ring gear, and the overrunning clutch or bendix , which is the springy part that kicks the drive gear into the ring gear.
When you remove the starter from the engine, you will see the drive gear on the end of the starter that was inside the motor.
The drive gear is about the diameter of a half dollar or a silver dollar. it should not be chewed up, it should look like a good gear. Inside the place where the starter attaches, you should see a ring gear, with a flashlight, and those teeth should look good and not chewed up.
On the starter you removed, behind the drive gear and usually inside the starter is the bendix or overrunning clutch , which will push the drive gear into the ring gear when you crank the starter. These parts often fail every few years.
Some people fix them, most people replace the whole starter.
Be blessed.

The way them starters work is it is either engaged by a silonoid or a reverse plastic gear so when the starter is energized the gear comes up so. In other words u can buy a new starter or take it to a shop and have them rebuild it. If it is the plastic gear kind u can geta new gear for it

did the belt break or fall off?are the push control rods pulled out to push it ?

check for spark is the wire on the spark plug is the plug good check for fuel flow possible electrical short

try a little light oil on the starter shaft
