No offense, but your seller doesn't sound like someone I would want to take advice from, based on the product he sold you and the lack of support. If he put ROPS on the machines he sold, he wouldn't need to give bad advice about turning front wheels around as a supposed way to protect you from rollover. The spindles and axles were not engineered for the force that is put on them when the wheel is turned out. It's fine to turn the rears out, but not the fronts. However...we have wheel bearings for most grey Yanmar models, and spindles for some of the 2wd models, so we can supply the parts when they fail prematurely.

Let me say one more thing to all readers, and please read this carefully before replying to this post. I know that many have turned them out and seen no consequence to date. That does not mean there is not a cumulative effect of fatigue on the parts involved. If you want to turn them out, or keep them turned, by all means do so. What I am stating here is the result of our experiences with the tractors and with parts calls. I would not turn the front wheels out on mine. Nor would I rely on a 4" wider front end to protect me from rollover when OSHA approved ROPS are so available.

I agree with LMTC's comments regarding the front wheels. I have a ym2000 and ran mine with the fronts reversed for four years with no problems. Then last summer I was driving across flat yard with loader bucket full of soft dirt. Hit a small pothole, heard a pop and left front dropped to ground. The spindle had broken clean off. Was able to get replacement and repair rather easily but I do think that having the wheels reversed probably did add to early failure. I have them back in normal position now.

My personal opinion - here are some more reasons it is pointless to turn the front wheels out:

Wayne (LMTC) noted the increased risk of breaking a spindle, due to continuous increased stress.

It's not just the weight down, but also shock from running the tire into something stresses it front/back also. If you expect a turned-out tire to stop a rollover, that abused spindle will be stressed worse than ever before, just before the tractor rolls over. That would be a bad time for it to snap off. For myself I prefer to not turn the wheels out.

My second point is that the front axle is on a hinge. It doesn't resist tractor tipping until the hinge is at the end of its swing, and the tractor chassis has come down to hit the axle. And that side of the axle is probably on the down side of a slope.

By the time the chassis touches the front axle, the opposite rear tire would be far off the ground. I don't think the front axle can stop a rollover.

After considering all this I bought a ROPS.

Thanks again to all who have posted. Everyone's advice makes sense. Kind of makes me feel stupid for even asking. Should have thought it thru more I guess. But then, that is what this forum is for, right? :D
I hope to learn a lot more from you all without the hard lessons.
Thanks again,
Craig

Kenmac,
I'm thinking of turning my fronts around also. How long have you had yours turned? Anyone else have any problems turning theirs around?
Thanks in advance,
Craig

Mabe a year ? I didn't turn mine around to prevent a roll over.With the rears as wide as they will go, the tractor looked like a tricycle with the fronts in the factory position .If you can tell from my pic. I do have a R.O.P.S.& would recommend to all that have tractors to purchase a R.O.P.S.

Wayne,

Would you clarify the certification for the ROPS that are for sale for the Yanmars. I was under the impression that they were tested/certified for front to back "flip over" and not necessarily side to side "roll over". I hope they are as I will be purchasing one soon, but I do not want to have a false sense of security.

Thanks,
Steve

What I can say first hand is that the ROPS we sell are certified to OSHA standard 1928.52. Following is a link to the OSHA site for more clarification OSHA Link
One of the substandards under 1928.52 on that site reads as follows:

1928.52(b)(2)
Field-upset test. A field-upset test under controlled conditions, both to the side and rear, to verify the effectiveness of the protective system under actual dynamic conditions.​

Where did you hear this ?


I have never heard this.I was told that they were tested for side roll as well as back flip.
