Will a John Deere 1050 ROPS fit a 336D?

[Rameck]

I just recently bought a Yanmar 336D with front loader, backhoe and scraper but no ROPS. Would like to put one on before I move it to my property up in Washington in about 5 or 6 months. Also, looking for a used one, if anyone knows of one. I know they have new ones but I am not ready to spend $800 for one yet.
thanks,
Ralph

I am confident that I can design, build and install a ROPS or alter an existing one on just about any style and model tractor. I've done this a few times in the past. Keeping in mind that the new structure has to incorporate controlled deformation and flexibility in a side roll-over or end-over incident that includes the attachment points it's not too difficult to make. Even allowing additional materials for strength for the back hoe attachment.

By the time someone acquires the materials or alters an existing one, builds, modifies and installs the unit there are some very serious implications for NOT taking on the task. In the event of an accident, injury or property damage your insurance carrier will not cover your loses (if you're honest and have disclosed the information). Should you sell, trade or give your Yanmar away, the liability for any injury or property damage will forever remain the builders responsibility unless you remove everything related to that ROPS.

IMHO, it's just wiser to acquire the correct ROPS designed for your model if available. And if it's not within the budget it's safer to operate without the correct unit until one is affordable.

Understand the legal liabilities but if John Deere made a ROPS for the 1050 and it's interchangeable with the Yanmar 336 then it would be just as safe on either tractor. My understanding is that Yanmar built tractors early on for John Deere and that is why some parts are interchangeable and maybe this was one. The best thing to do at this time is see some close up pictures of a JD 1050 ROPS and how it's mounted on the tractor to see if they are designed the same. If anyone has a JD 1050 with ROPS, would appreciate closeup pics of the ROPS where it's attached to the tractor.

thanks,
Ralph

Ralph, this company made the rops for my Yanmar 140D.

Custom Products of Litchfield

Did a nice job, compared to some other aftermarket ones I've seen.

Good luck with your project.

That's the firm who builds the ROPS offered by most of the gray market dealers you see here.

See: http://www.hoyetractor.com/ROPS 4 instructions.pdf, which shows Custom Products as the manufacturer.

My theory is that Custom Products dusted off the blueprints for the ROPS they provided to YanmarUSA 20+ years ago and went back into production, this time to fill an order placed by Fredricks. C.P. may have blueprints for a YM336 ROPS. Getting them to resume production is another matter.

I think this illustrates that parts offered by these dealers are first class!

That is not at all what occurred in the process. The ROPS for each grey market model was designed specifically for that model, and tested on them. SIGNIFICANT expense was incurred in design and testing of these new ROPS.

No intent on my part to flame, just to set the record straight. I'd use a bunch of smileys, but I really prefer to just openly state my intentions (or lack of same).

I don't know the following for fact, but I'd suspect the prints/rights to the ROPS for domestic Yanmars belong to Yanmar, not Custom, as Yanmar surely would have paid the R&D costs.

LMTC, do you know if there is any interchange between the ROPS for Yanmar made JD's and Yanmars? Or other parts for that matter?

Kubota seems very determined to make ROPS available for older units. I don't understand Yanmar's approach to the tractor market, much less what Yanmar is doing to make ROPS available.

I do not....but I do know that unless a ROPS is designed & tested for a specific unit, it's not going to be OSHA approved for it. Simply fitting is not enough. Remember, the compacts Yanmar made for JD may share some parts with grey market Yanmars, and in a very few cases be very similar, but they are not the same exact tractor.

Thinking about that last sentence, that makes sense. Yanmar wouldn't want the liability associated with re-releasing their designs so C.P. would have had to start from scratch.

I should have stuck to my intended point: these present ROPS should be as good as OEM because the distributor had them designed and manufactured by the same specialist that Yanmar used.

I'd say you're right...and they are all folders, which is convenient and usually costs more, and there is a XX extra-rotund seat belt extension available (which I need) at nominal cost.
