Can't find Neutral on Cub 105

[cadzag72]

Chances are on a hydro that your brakes are totally fine, you'll see once you have yours up and running that you really don't need them.

Hey thanks guy. I really appreciate it. I was looking to roll in with the motor off. I can honostly say i know nothing about hydro tractors. I did end up moving it by jacking the rear up and pushing on the jack. I am going to try to start ot and go from there. I was under the assumption that it was like a gear driven tractor and that it will move it neutral with the motor off.

Here's a picture of my 125 showing the lever that is moved to allow the tractor to be pushed a very short distance.

Yeah, I was able to push it a short distance with that lever. I now understand that Hydrostatics don't move when off and in neutral. I got it started and it shifted fine for the short time I was able to. I'm now having trouble with it staying running. It starts up fine ( full choke ) then dies after a few minutes. I tried playing with the choke to see if it will run in a different position but it just dies out, no spitting or sputtering. Full throttle to off. BTW this site and the help has been great.

Good luck with it, you've got a great machine. Plenty of help available here, too. Download the manuals, ask for help when you're confused, we'll take care of you here. Have fun with your 105!

By the way, sounds like a fuel flow problem. Something partially plugged somewhere.

I agree with a fuel flow problem. My gas mixture in every single gas can is a few ounces of Marvel Mystery Oil and Star Tron gas stabilizer.

The crap they sell as gasoline now doesn't have much of a shelf life. The MMO and Star Tron help a lot.

If it starts and runs for a few minutes and then dies (the choke may help, too) it's 95% a dirty carb. Remove the carb, disassemble and clean out the gunk in the bowl and all the passages.

I just did this with two of my tractors yesterday. sitting for a year with ethanol in them does not have a good outcome.

Little globs of gelatinous goo (phase separated ethanol) in the bowl and plugging up the passages.

If you have a rebuild kit, go ahead and use it. If not, as a temporary repair, you can go back with the existing gaskets, etc., but risk a sticky float valve, and a subsequent repair. In a pinch, just clean and re assemble.

Remember to turn the jet screws in until they seat, counting the turns, and then remove them. Upon re-assembly, screw them all the way in, and the unscrew the same number of turns as before. (NOTE--they may be wrong to begin with, so if in doubt, refer to the service manual).

It'll run like a champ afterwards.

You guys ready for this ?!? Man did I overthink this ! I drained the old gas in the tank, and removed the carburetor. I tore the carb down, cleaned it and reassembled it. Upon placing it back on, I attempted to start it, but this time it just wouldn't even start. It just turned and turned. I then looked at the fuel bowl attached to the tank. I took that off, and cleaned it. While looking at it, I noticed that the little screw was all the way in. I unscrewed it, and noticed that it was a fuel shut off valve. WELL...... I put it back on, fill it up, opened the valve, and low and behold the tractor starts right up. I then sat down,cracked a beer and started to laugh.....

The good part is it was something simple. I'm sure every single one of us has done something similar.
