Replacement seat for my 135D??

[gbart14]

I need to replace the seat on my 71 Yanmar 135D. Are there any original style replacements or what would you suggest?

Hoye probably has the chineese replacement seats for them?

There's one model seat everybody including Hoye and Ebay have for a reasonable price. But in my experience that seat crowds you too close to the steering wheel - and I'm not very tall. On a tiny Yanmar (my first YM186D) it was a real nuisance, so tight it was difficult to dismount.

Now on my second YM186D, the one I found with a loader, I retained the original Yanmar seat even though it was bare metal. I had to weld some minor cracks, now a couple of years later it has held up fine. I glued in a layer of foam mat plus have a removable cushion on top of that. I like this better than that 'universal' replacement seat, there's considerably more space measured from the steering wheel to the seatback.

I just noticed your photos. Is that seat original? It looks considerably more spacious than that universal replacement seat. If you like it, take it to an auto upholstery shop and get it recovered.

I managed to get one that has the slide on it for adjustment on my YM14.

That is interesting California, I have that same "universal" one that everyone has. I would like if I could move back some from the wheel. But this is all I have known and I guess closer to the wheel gives me more leverage on the steering wheel.

California, thanks for your input. I am pretty sure based on the look of it and the pouch on the back of the seat back that it is original, remarkable as it seems. If I cannot find something close, I will do the reupholster route. Would be great to find something like it, though.

Mine sits pretty well back. The seat back is fairly thin. I am fairly big guy and have plenty of room to get on and off. The seat bottom is loose with broken plywood that was part of the seat and needs to be redone. I'll post some pics of the structure under the seat later today. If I had to replace it completely, I would want to get something adjustable like Neat 1500 has. Say, Neat 1500 don't you guys need a seat belt to keep from falling out because you are all upside down -
yes?? Hah!! Thanks, everyone.

FWIW...20 plus years ago the seat on my 187D broke... I went down to my local boat dealer and bought a "BIG MANS' boat seat. Installed it easily and it's still on my 'little mule'. Pure comfort. Geo

This sounds like the best solution of all.

I am pretty sure that is not an OEM Yanmar seat.

Do you have any photos or links to an original 135D seat? Thanks

If we closer I have the original seat off my 147D you could have. Don't know if it fit. It was in good condition just wanted something "new and improved" .

if there is plywood its not original. The originals had a metal pan under it with upholstery/vinyl and foam. Had a low curving back.

And I should have mentioned this but my replacement seat that came on my tractor has a tear in it, starting at the drain hole and going to one of the sides. The thing never sits out in the sun. The little bit its in the open I tilt the seat forward and usually will tarp the drivers area, gauges and the hydraulic top of the tractor. And I have only put 120 or so hours by the yanmar gauge on it in the last 9 years.

OK, dug around on the seat and took the attached photos. It tilts forward and looks like the frame was adapted from something else. Or, if the frame is right, the seat cushions were adapted from something else. You are right, it is not original. It is old but not original. Does anyone have a pic of an original seat and also the seat support? Is my frame original? This frame was set up for a two piece seat with the back being able to pivot to the back for convenience. If not, I think I will buy a new seat bottom for now and install it and enjoy it. Comments?? Thanks

I think that seat is at least as good as what came on there, and it's worth rebuilding as needed.

What I have seen on Yanmars is that hinge pin across the front of the seat, and the seat pan supported only by springs directly beneath your hips. (springs attached on top of the differential, not attached to the seat pan). Then just a simple curved one-piece seat pan/back. I think the littlest Yanmars had a low rise seat back no higher than your jeans pocket, maybe including this model? All that other structure you have under there seems to be something a previous owner fabricated.

Was that '71 model' a typo? It's around 1979-81, that external air cleaner on the left wasn't used before then.

135 seat.

That seat frame , although cobbled together, looks very serviceable. If mine I would just rebuild it, otherwise you would have to re re-invent the wheel. to accomodate another seat. Looks like they had to bend the 3ph lift lever to make it fit.

yep no doubt about it that thing is NOT original, not with all that's going on in there! It must weigh a ton with all that 2" square tubing and stuff! But I agree, id get some new wood and 4" dense foam or whatever works and some outdoor sunbrella fabric and a new piece of treated ply or normal CDX if you keep inside and bolt the wood and glue the foam to it and stretch and staple your fabric onto it. Even the Chinese seats would not come out any cheaper than that. and would not be near as comfortable as what you have.
