Customer Question

I have a z225, 18.5hp briggs engine. Using it the other day, I cut about 1/2 of our 2 acre lawn. I shut it off to move something, not it won't start. The PTO is off, the parking brake is on, the steering arms are open. When I turn the key, the starter motor "clicks" but the flywheel doesn't turn. I removed the cover for the motor. I can see the starter gear engage the flywheel gear, but it won't turn.

Welcome to JUST ANSWER small engines, let me try to help you !! Can you turn the engine manually? What is the battery voltage? Has to be above 12.5 volts for starter to engage. Safety switches are working or starter would not click.

Yes i can turn motor by hand, battery is new, about a week old.

The starter engages, when the two gears meet, it just stops

No way to test battery voltage? Seems to be low voltage
Customer: replied 1 year ago.
12.55 volts
Expert:  Curtis B. replied 1 year ago.
Fully charged battery will be over 13 volts. What does it read when you engage the starter
Customer: replied 1 year ago.
voltage drops to 5.95 when the starter is engaged.

Battery voltage is too low to engage the starter!

Ok, didn't think to check it, it's a new battery & it started no problem & ran for about 2 hours. I'll get a new battery now, thanks

You may have a charging problem, but battery is dead!
