  • #1

Almost two year old Toro SS4225 Time Cutter with 22.5hp commercial engine has started to become impossible to start since last fall. Turn the key to start and starter solenoid clicks rapidly, notice the fly wheel cover starts to move but nothing.
1. Checked the battery voltage, 13.4v+/-
2. Check starter solenoid, listen and fell for clicking noise
3. Check voltage at the input side of solenoid, 13v
4. Check voltage at side connected to starter with key turned to start position, 12.8v
5. Even though solenoid seemed to be ok tried shorting the voltage across solenoid, same results starter engages but does not turn flywheel at all
6. Removed engine flywheel shroud/cover and turn engine over by hand, some resistance most likely compression
7. Tried to start again, same results
8. Repeated turning engine over by hand and try to start again, this time started.
9. Let engine run a few minutes to charge battery up a little and then shut off
10. Turn key to restart, no issues started up fine.
11. Replace engine flywheel shroud/cover and park in building
12. Two days later try to start and same issue, have to remove shroud/cover and repeat process
13. Purchased new solenoid and battery just to rule out and same issues.

Why must the engine be turned over by hand when cold, is the starter that much of a POS, I had it bench tested at a Toro shop and was told it was ok.

if you take the spark plug(s) out, will it crank over?
i'm suspecting the valves are out of adjustment. however, i think if you can turn the engine by hand, the starter should be able too.
Did the toro shop test the starter under load? you may have to take it to parts store like o'riellys and ask them to test it, FREE.

I have not taken spark plugs out to try, the bench test was done in back to where I could not see but I did hear it working and as fast as he had it working I would say it was without load. Is it normal to have to adjust the valves on this type engine? Once I have it started and its warmed up the starter has no problem re-starting it after shut off many times, its only after it sits for couple days that seems the starter can not fully turn flywheel over as you can see it slightly moving before starting to make clicking noise.

Valves are usually adjusted periodically at X hours depending on the manufacturer.
but since it runs good when it starts. it is probably not the case.
try cranking it with the plugs out.

I believe you have a 3 yr warranty , can not a dealer figure out what is wrong with your mower, I have the same exact mower, any problem’s, the dealer has taken care of it, I do not have too worry.

Regardless of what your voltmeter says, your battery is DEAD. You can only test a battery with a Load Tester.

Put jumper cables on it from another battery & re-test starting. But if yours is under warranty, be careful what you attempt at home.

Battery taken out was tested at autozone and found to be good, even so still bought a brand new battery with same results.

FAQs

What would cause a zero turn mower not to turn over? ›

Check your filters

If it's not fuel or spark plug related, chances are it'll be related to the carburetor. Directly linked to this are your air and fuel filters. Dirty air filter - to make the engine run the carburetor needs air so if it's dirty or torn it may not be letting in enough air for the mower to run.

Why does my zero turn make a clicking sound when trying to start? ›

The clicking noise comes from a part called the starter solenoid. The solenoid connects the battery to the starter motor when the solenoid is energized. The key switch and the safety switches in the starter circuit combine to energize the solenoid. If the solenoid is clicking, the circuit that triggers it is working.

Why is my mower not turning over? ›

Your Mower Won't Start:

If you have last season's gas in your mower, drain your fuel tank and fill with fresh gas. Other possible causes include: Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace.

Where is the ignition switch fuse? ›

The fuse box is usually located under the hood of your vehicle near the steering wheel. In some vehicles, the fuse box is located in the glovebox.

Where is the starter solenoid fuse? ›

Most often, a true starter relay is a small black cube plugged into an electrical fuse/relay box in the engine compartment, whereas a starter solenoid is (in most cases) attached directly to the starter on the engine (although it is sometimes located elsewhere in the engine compartment).

Why is my mower clicking but not turning over? ›

If your riding lawn mower engine clicks when you turn the key but won't turn over, there's a pretty good chance your mower could have a bad starter solenoid. Other problems, though not as frequent, include a bad starter motor, a wiring failure, a weak battery or a locked-up engine.

Why is my engine clicking but not cranking? ›

This clicking noise is usually caused by one of five things: a dead battery, loose wiring, faulty starter motor, faulty ignition switch or corroded battery terminals. In this article we will look at each of these issues and discuss how to diagnose and fix them.

Why does my starter solenoid click but not turn over? ›

If you hear a clicking noise, but there's no power at the solenoid, there's a problem with the starter control circuit. Because the clicking indicates that the relay is working, you'll want to focus on the portion of the circuit between the relay and the starter.

Does Toro have an electric zero turn? ›

Electric Zero Turn Mowers | Flex-Force 60V Max Battery | Toro.

When I turn the key on my lawn mower, nothing happens.? ›

Check the Battery

A dead battery won't power up the starting system and will prevent the solenoid coil from clicking. To see if the battery is dead, measure voltage across the battery terminals using a multimeter. If it measures less than 12 volts, the battery is weak or dead and you've likely found the problem.

How do I know if my spindle is bad on my zero-turn mower? ›

A bad spindle can produce grinding, rattling, or squeaking sounds, which indicate that the bearings are worn out or the spindle is bent.

How do you know if the starter or solenoid is bad on a riding lawn mower? ›

Bridge the gap between the posts with your insulated screwdriver. If the starter spins when you make contact, the solenoid is bad; if the starter does not spin, the starter is bad.
