I got this tractor from a friends Dad for free. I got it started just by getting a new battery and cleaning the carb. I am not familiar with these engines or tractors. I did try searching this site for the problem but if it does exist I didn't ask the question right. Wouldn't be the first time. I had to put a new tension spring on the mower and I replaced both the belts. Got everything running and was looking forward to trying it all out. I pulled the tractor out, stopped, engaged the mower and then the tractor would no longer move. I disengaged the mower and it still wouldn't move. Turned the tractor off and restarted then it would move as long as the mower wasn't engaged. While waiting for the mower parts I was driving the tractor around and it seemed to have a similar issue when it just stopped moving. Turning off and turning it back on got it moving and I could not recreate the issue again. The mower issue recreates on demand. I checked the oil level in the hydraulics appears to be correct. Not sure what to check after that. Any help would be greatly appreciated.

Check to make sure the hydro is fully engaged. The knob in front of the seat should be turned fully counter clockwise. If that isn't the problem, I'd guess that the valves under that knob are sticking. They can be soaked in PB Blaster or similar over night to free them up. That usually works.

If that doesn't work we can look at the charge pump.

A serial would help figure if this the early or later 316. Possible drive shaft issue?

If the engine was cutting out when you tried to move it’s probably seat or pto switch related.

That's a good thought. The moving of the tractor and the mower deck are only really related by the motor. Each are separate functions.

Mike, what knob are you referring to.

Mike would be referring to the "free wheeling" knob...an 8 sided (??) star shaped knob in the center of the tractor (left to right) and just below/in front of the seat. Turning this clockwise pushes down on 2 valves allowing hydro fluid to bypass the drive motor. Full counterclockwise should allow the valves to pop up and fluid then goes into the drive motor and moves the tractor.

Sorry to jump onto your request Mike, but I just happen to be here! Bob

The knob right in front of the seat. It operates the pressure relief valves. Screwing it down, clockwise pushes the pins down allowing the pressure to bypass the valve.

It was my first thought because it seems every single time I haul my 300 somewhere the thing screws down some and the hydro acts Goofy and I start to worry about what's wrong and then I realize, duh, it did it again.:banghead: I've fallen for that more than once.

The engine doesn't start missing during this. At least not anymore than it was to begin with. It runs pretty well but there is still work to be done. May have to rebuild the carb. Certainly will replace the plugs.

Thank you for the response. Didn't get a chance to look in here yesterday and I am at work now. I don't recall this knob but will check for it this evening when i get home. Would be great if the solution is that simple!!

Only the 316 kohler has the knob. The 316 onan has a lever behind the right rear tire.
OK. This one has an Onan. Makes me feel a little better about not remembering this knob. A lever behind the right rear tire would be something I could have missed. Will check for that when I get home. Still a simple solution.

We keep rydplrs around to finish my thoughts. The onan would have the lever. Doesn't mean the valves aren't sticking so.

I can post this when I get home. It has an Onan engine (an no oil filter?)
Apparently I had plans when I got home. Managed to get a few minutes to look at it. As best I could make out the serial number B43E-GA016/4130A. I looked around the right rear tire and did not see a lever. Probably because I am not sure what I am looking for but nothing jumped out at me as the solution to my problem.

I took a few pics and if I get them to show up maybe someone can point out the lever I am missing?

More than happy to take more from better angles if it helps at all. MIGHT be able to spend more time crawling around it this evening. Maybe the lever we become more obvious then. Thanks.

Thank you. I found it. Unfortunately it didn't solve anything. I read my description again and realized it wasn't as clear as I thought. It doesn't just stop moving the instant the mower is engaged. I will stop. Engage the mower and start moving again. It will require the lever be pushed all the way forward and it will lurch but move. But it won't go very far before it simply stops moving. Turn it off. Wait a few minutes and then try again. Sometimes it has to be started and turned off a few times before it will start moving again.
