Lawn Tractor -Starter?
Posted July 10 2006 - 07:22 AM
Was trying to be a nice guy on Saturday, and after finishing my lawn, figured I'd make 2-3 passes on my neighbors side of his driveway so he didn't have to drag his push mower all the way down from his house to do it.
The "grass" was long and wet, and the tractor bogged down. (I TOLD YOU LAWNS ARE EVIL!!!!)
Anyway, cleared the wet grass from the underside, but still couldn't get it to start. Turn the key, a few clicks, then nothing.
After pulling the starter solenoid, taking it apart, and cleaning up the contacts, I bench tested that and it works fine.
This AM I pulled the engine housing to expose the starter mower and fly wheel. The flywheel turns easily by hand, so I know the engine isn't seized.
Turn the key, and I get a click, the starter motor throws out to engage the flywheel like it should, and then nothing, and I lose power at the aft side of the solenoid.
So, starter motor shot? Is what I'm thinking. As to losing power on the aft side of the solenoid, I beleive that is becasue they are rated to handle only so much torque/amps, and then they automatically cut out.
If I jump power over the solenoid directly to the starter mower, it throws out, and when it engages the flywheel, it just stops.
Next step is to pull the starter motor and bench test it, but even if it works at the bench, am thinking some of the coils in it may be burnt, and it can only throw so much torque before it stops.
Does all this sound correct?

One question. You sure it's got gas?

i'd check the battery , had that problem with my mom's lawnmower ... battery solved it ....

Very similar symptons as I was having, throw the key and you here the solenoid click and the starter throw the bendix out, but no rotation. Put the new battery in turned the key, Viola. 2 dead cells in the old battery. Take the battery to your local auto parts store and have it Load Tested, it well tell you what's up quickly. Besides, the batteries easier to remove than the starter.

If that doesn't work, my neighbor has an old Craftsman tractor up at his place that is half taken apart....knowing Steve, it is just junk, so am sure I could cannabalize the starter from that one if it happens to match up....taking out the starter is fairly simple at this point, just four bolts....
Will let ya's know later, and thanks for the input....

Besides, even if it didn't, I'm way past that point in the diagnosis, and it wouldn't matter for what I'm trying to achieve.....

Jump started it, and the starter works fine.........
So.........guess it's off to get a new battery, but that can wait for now.....cause as long as I have the thing all apart, I might as well give everything a good cleaning to remove all the dust and debris and a general going over....new plug, new fuel filter, etc......but not today, it can wait, as the garden needs more attention right now, and I don't plan on mowing THAT EVIL THING for at least another week and a half......
Thanks for the input, and I should have thought of that to begin with....

Extra battery here... rebuilt Craftsman 11hp/engine rebuilt, lost the darn valve spring cover, so can't put on the card and intake yet (probably a $2 part)... tired of it. No brakes, who cares
Bulletproof hydrostatic Toro 14hp OHC like new, took 3 years to find a good one, paid good $$$, too late to sell, never cut my grass with it, don't need it for the new shack, no Sol'ers near by
Besides all that, catch any fish

Please check your battery and make sure there is air in the tires, more on the left side then the right side and have a beer or 3, and you should be fine.
Happens all the time, Trying to be nice.
Tomorrow is a mystery.All we have is todayand it is called the PRESENTbecause it is a SPECIAL GIFT!

Just took the battery to be load tested at my automotive guy's shop. He tells me it is fully charged, and putting out almost 300 amps under load (the tractor should only take about 60 amps, or so he said), and coming right back up to correct voltage.
The other day when I "jump" started the tractor, it wouldn't start with a traditional jump start, though it would sporadically throw out the starter to the flywheel, but wouldn't turn the engine.
But if I jumped it by by-passing the solenoid (car battery ground to tractor ground, car battery + to the aft side of the solenoid), it started right up.
That leads me back to the solenoid.....
Next, gonna try using the tractor battery on its own, and by-pass the solenoid, and see what happens......maybe a bad battery to solenoid wire?

If you have a good battery and starter, and your getting intermittant cranking, worth looking at the cables. Just a thought.
