So, I posted in another thread, but figured it would be better to post a new thread. I hooked up the RO30 to the mower with an overrun coupler. It was not a great fit and there was some slop in-between the coupler and the pto. When I started to mow the tractor died. This does not normally happen. I can use the six foot blade for hours. It is a five foot finish mower, btw. Any help is appreciated.

You getting fire at points? Do they need setting? 6 or 12 volt? Check and post info so
we can help.

It is converted to 12 volt. It runs well without the mower hooked up to the PTO.

Thanks,
Chris

check the fuel delivery - could be running out of fuel when it's asked to work - the pick-up can be obstructed in the tank with scale or whatnot, the screen/sediment bowl can be full, and there's a screen associated with the brass female fitting where fuel enters the carburetor that can fill up -

the mower turns freely, right?

Okay, I will check the fuel. I think it did have old fuel in it for a while. I sometimes have to hit the carb with a hammer. I put some stp in it a little while back. It is possible the fuel has not worked its way all the way through. Yes, the spindles move freely. I greased them all and raised the mower and turned them by hand and they move fine. Would the slop in the PTO drive cause it to die as well? I was thinking it might have to work harder, since it is not a tight fit.

Thanks for the replies.
Chris

'slop in the PTO' would not cause it to die - - you are aware that the yokes associated with the PTO shaft need to be synchronized (for want of a better word)? - most shafts will not go together incorrectly, but some do - I still don't think it would cause the engine to die, but it would be noisy at least and lock up at worst (only at a big angle)

Check your ignition. With the throttle closed as it will be when not under load the compression won't be real high and a poor spark can still jump the plug gap and ignite the fuel. Opening the throttle such as under load increases the compression and the spark can no longer jump the gap. Make sure it has a spark that can jump a minimum of 1/4 inch in air.

Would you mind to explain how to do that? Thanks, Chris.

This is probably the easiest way to test the ability of the spark to jump a gap. If you are daring you can just hold the coil wire away from the engine to see if it sparks but it might decide to spark to ground through you.

Is it possible there is trash (long grass a piece of rope or something else) binding in the mower? If the tractor works fine not using the PTO then
I would suspect the implement not running freely

Thanks for the link on the tester. I will pick one up.

IRT the mower, I raised it up with the tractor and spun all of the spindles by hand. They all turned freely. The mower cut about a 10 foot area, but that was with the tractor dying four times. so, I know it will cut. I just was not sure if I was putting too much of a load on the tractor with the PTO drivetrain sloppy, but it sounds like instead it is the tractor just not being able to work up to par. I plan on checking on the gas and spark plugs this weekend.

A couple of thoughts. I wonder if your blade loads up the engine as much as your mower. Do you have another implement such as a plow that you could really make the engine work, without the PTO, as a test.

If it still stalled, I would suspect insufficient fuel as well. Another possibility might be governor issues. Another way to test the governor is put it in 4th gear, medium throttle and slowly let out the clutch part way. Watch the carb linkage and see if the governor opens up the carb fully. Hold it a while and ensure that it does not stall. It should stay running loaded up to the RPM is near idle speed. (This also sort-of tests the fuel flow as well)

I am sorry, but I forgot the most important part. Make sure that you have your foot on the brakes. Exclamation Rolling Eyes

The idea is to use the brakes as your load to force the governor to work. Embarassed
