super A won't turn over

My 1950 Super A won"t turn over. Went to start it and it fired then died. Then could only get an occasional ruuh, if anything. Had the starter rebuilt and have cleaned grounds and by-passed everything and tried different batteries. No luck. Can turn gear wheel with long screw driver and hear tappets, but apparently it"s too tough for the starter. Can anyone suggest what might be the problem?
 
There must be a problem with the starter is didderent batterys wont turn it over. Will the starter run if its out of the tractor.
 
If you have a voltmeter put the black probe on the negative CABLE--not the post, on the battery. Attach the red probe to the positive CABLE at the battery--again- not the battery post. See what the battery voltage does when you try to start the engine. If the voltage drops to less than 4 volts when cranking, your terminals are probably not clean/ tight on the battery posts. Other possibility is a bad cell in the battery--unlikely with a new batt.
If voltage remains high while trying to start the engine, the starter needs attention again, or switch/ solenoid problems.
 
Assuming it is 6 volt, are your cables good, and big enough? 0 gauge? Sometimes they'll look nice on the outside, and be pretty cruddy inside, and not let enough juice to the starter.
 
thanks for the input. I've tried 3 batteries and by-passed the cables and attached directly ot the starter and the starter works good on the bench.
 
You should install new 00 battery cables and don't have them any longer than necessary. Solder the lugs on the cables. Then clean all the lugs until shiny & the battery posts. Clean the area where your battery is grounded too as rust & paint are good insulators. Hal
 
Thanks. I think that's my best bet right now. I'll clean at the ground connections, since I think I've covered everything else.
 
I would crank it by hand, and if it is free but will not start, I would pull start it. If it is an engine issue, fixing the starter will not make it better. Pull the sparkplugs and see if that allows it to crank easily! JimN
 
You've definitely got a bad connection somewhere.

I'm assuming you bypassed the battery cables with jumper cables? That really doesn't tell you much because even top-end jumper cables won't carry enough current to start most engines on their own. There simply isn't enough contact area on the toothed clamps. That's why you're supposed to wait a few minutes after making the connection before you attempt a start... It's to charge the dead vehicle's battery a little. Jumper cables are only really "booster" cables.
 
you could have a problem with one of your cables if starter motors good when bench tested,double check grd connections also clean starter to bell housing surfaces, get a good cable try replacing one cable then the other, if this doesn't work check starter switch if it is pull type,if it uses a sol. bypass it by removing one cable from sol.terminal and touch it to the other,don't forget that the cable from sol.to starter could also be bad, BE SURE TRACTOR TRANSMISSION IS IN NEUTRAL be patient it is something simple
 
A few years back I was pushing snow with my cub and suddenly the tractor stopped dead (died) in it tracks. Wouldn't turn over with starter. I discovered that the fan bearing had suddenly frozen up and stalled the tractor. To get it back to the shed, I cut the fan belt which allowed me to start the tractor using the starter. I replaced the fan bearing and belt and was good to go.
 
Will do. I believe a tractor expert is coming over in a few days to have a look. I'll let this forum know what comes of that.
 
TURNS OUT USING JUMPER CABLES DOES NOT WORK. ATTACHED NEW BATTERY TO PERMANENT CABLES AND TRACTOR STARTED. SO IT WAS THE BATTERY.
