Hello all and greetings from Michigan.

 

My tractor is giving me issues, money has been tight and I've been try to bandage this thing together this mowing season.  My tractor has been out of commision on and off now for the past 3 weeks.  With the amount of rain we've received, my lawn is less than desirealbe. 

 

So here is my goal, A- get mower running, knock down the grass, mow again, and probalby mow a 3rd time.  Take the tractor in and have a professional look at it.

 

So here's my problem.  It's electrical.  I'm sure the solenoid is bad, I've been able to jump start it a couple of times but now it just barely turns over, the other day it started right up with a jump (of course murphy's law- flat tire), so some days I can jump it, other days I can't  When I do jump it I'm going from my runnning car to the neg post on the tractor, pos to the starter.

 

Any ideas on why it's so moody?  Any help would be appreciated!

 

Thanks

What kind of mower and how old? Charge the battery. Check to see if the ignition switch is working properly. When jumping the battery you need to do it the same as you would a car or truck. Positive to positive and negative to negative. If the battery is no good it wount start thr tractor.  Lets start there. Roger.

Step TWO-  Clean your main cable connections!

Does your tractor have a OHV Briggs & Stratton Intek engine in it?

 

 

Reason I'm asking is,the valves get out of adjustment on Intek OHV engines and it disables the compression release.All you will end up doing is cooking the starter if you jump start it.

First off let me welcome you to GTtalk.  Please give us some more details as to the make, model, year of the tractor and what engine is installed.  Pic's are always a good idea so we can get a visual of what you are talking about. 

 

Jumping from the car to the starter is not a good idea, as mentioned you will burn up the starter.

Step TWO-  Clean your main cable connections!

 

At BOTH ends! (Especially the neg-ground/frame connection and check to see if the cables are still "cable" inside the insulation.  Battery corrosion does funny stuff inside cabling.

Thanks for all of the comments, I believe I've answered everything that you've stated.

 

The tractor is a Huskee 18/hr with a B&S Intek engin.  I have charged the battery, cleaned the ground to the frame, wire brushed the terminals.  I'm wondering if it is compression related?  I know a lot of guys here on the forum do that themselves, but that's way over my head.

 

I was really hoping for one more start before taking it in...

Forgot to welcome you aboard yesterday Sparty!  

 

Load test the battery as you've gone through the wiring connections..  New ones out of the box have been bad at times.  

 

If that's OK, and it still cranks slow-  Try turning the motor by hand..  I drive belt hanging up or something mechanically making the engine hard to turn will cause your trouble.

 

Someone above asked if it was an OHV engine which it is..  It may be as simple as a valve adjustment..  There are how-to videos in youtube how to do that..

 

Lastly, I'd remove the starter and bench test and clean/lube it up..  Also many videos on YT..

 

All I got..

 

Good Luck!

Sounds like what you and the members said is what I would have done so far. At this point I would put a volt meter right at the starter stud and the starter case and see what reading your getting while trying to start , , if you have battery voltage there and the starter doesn't work maybe a bad brush or other internal starter problem , get it a little tap with a hammer just in case it's just a brush maybe you'll get lucky. If the voltage drops you'll have to see if it's the engine mechanical or a bad starter ,  try turning the engine by hand it if moves ok might be a bad starter , they there are other ideas and am sure you'll hear them

Set the Intake Valve lash to .004-.006 Set the Exhaust Valve lash to .006-.008.

 

I've set them both at .004-.006 before but carbon build up on the exhaust valve will burn off and close up the gap to much and you'll end up burning up the exhaust valve.

I can't remember if the B&S Intek engine has the starter solenoid as part of the starter or separate.  I'm thinking if you are jumping it with the positive lead at the starter then you may be bypassing the solenoid in which case that could be your problem.  Do like ALC suggested and take a voltage reading at the starter connections while cranking. If you don't have voltage then check to see if you have voltage at the solenoid wire from the ignition switch. If you don't have power on that wire then it is probably the switch and if you do then the culprit is probably the solenoid.  Also like suggested earlier do a load test on the battery, as a rule of thumb you need 12.8 volts to kick that starter over.
