That's sounds like a nightmare to troubleshoot but good job finding it.

the small 16"ers dig into the mud, and the rear tires doesn't seem to have enough traction, they have like a turf tire tread pattern

Your trans is a Hydro.  I bet it was getting a bit overheated there at the end, maybe also a little moisture in the fluid when it was hot. That could have been the cause of the slowdown and maybe harder to move.

yeah, thoes 16" tiers suck for steering in mud, and thoes 35" tiers suck for gripping in the mud. long video with more problems coming soon. but this big tractor is a joke compared to dinky.

think i should cut every other tread out like people do to turf savors?

probboly, but i also think i might not have enough fluid in it, on the drive there after i basically left my yard i was going in pulses. when i was heading back, when i stopped at the gas station i noticed oil dripping in the front and back of the tractor, back side seems to be comming from were that hydric line goes to the blade deck, front was coming from the motor, motor went from topped off on oil to just blow the minimum fill line. i think my red RTV crank case gasket failed there.

btw when i got out of that mud hole, (did not think to touch trans) the pump was hot, but not somthing i cold not hold hot.

when i eddit the video you guys will see it as soon as its done, theres even fun stuff like me having the camra rolling while getting partaly run off by the 990.

the motor on this is a keystock sheering mashine. this tractor is dead till i find stronger keystock, have stronger key stock made, or just weld the damn fly wheel on as a last resort.

So what I have done to prevent a shearing was make sure the crank shaft keyway is tight, check the flywheel and make sure there's no slop, then I put a thin layer of in weld on the mating surfaces and torqued that "Female dog "down. Hadn't had any issues till the block blew up.

I mean, if the flywheel is out of balance (which it will be), it's no mystery that it's gonna shear the key constantly no matter what ya do. What did you torque the flywheel nut to?

it shears when it misfires usealy on a start. its never sheard while running. and torqe? i just use a pipe wrench and bash the handle with a hammer untill it stopps getting tighter. i cant turn it by hand and even get it snug.

Your threads are most likely messed up. It should go on smooth until snug.

ok, this things alive agin, i welded the fly wheel on and i messed with the governor its it has way more speed and power and dose not bogg down any more because the governor properly brings the throttle up under a load.

i would bet that im done with fly wheel problems for the rest of the motors life unless for some reson i need to take it off. you said i could not weld the fins back on the fly wheel, and not one i have welded on has came back off.

also i played with the govonr setup and that part of it runs GREAT now. i have so much power. at the moment that motor is my best running single and it runs better than it has ever ran since i had it. i dont even have to choke it to start it with the governor working right.

oh, and both the motor and the trans oil leak has slowed down immensely since i started using the thing alot. to the point i have gone 2 weeks and haven't noticed the motor or trans oil level drop.

I cannot stress this enough. The flywheel key is nothing more than an alignment tool. It does not stop the flywheel from turning. It's not supposed to.

The thing stopping the flywheel from turning is the torque on the flywheel nut. If the flywheel nut is not properly torqued, then the flywheel will spin and shear the key.

If you put a steel key on that crank you will tear the keyway out of that crank, and potentially crack the flywheel as well.

its been dealt with and wont be a problem any more. the motors never ran better. i do on the other hand need to see if i can find a new belt for the startor. or remove the starter and make it were i can pull start, witch i would like more. well id really like both.
