why tym tractors loader lift rateings so much better than jd?

when your in the line of work that Art and I are, you quickly see that all equipment is not created equal. Somehow that impression is being lost on the internet. Owners of mediocre products will defend its virtues so their personal thinking that they made the right choice stays intact (lots of studies on this) and you end up with a 'everything is good, everyone wins' consensus so no one is offended.

Yes, the good and the bad combine in time to become the mediocre.

One reason may be that different generations value different things - & that's probably as it should be.
Half a century ago, quality was the most important consideration because quality implied durability and repairability. If the price was too high, people either repaired something used or went without.

But my young friends today place their primary emphasis on initial price. Quality has become less important. That's right for them because as they see it, the durability and repairability mean nothing if they can't afford the item in the first place. And they simply do not have the same option to repair things that the older generation had. Both our culture and our manufacturering companies have worked hard to reduce the average owner's ability to repair their products.

What happens when you over load a FEL ? I just purchased a used TYM T273, FEL seemed strong, I tried to lift too heavy of a box, now loader won't lift any weight, any ideas ?

Is maybe the relief valve stuck open?

What happens is generally that it just won't lift it. If you rev up to full throttle and try then what usually happens is that the hydraulic relief valve makes a loud squalling sound as it provides a bypass path for the fluid. Then if you let off of the lift lever and the noise stops then the relief valve is simply doing what it is supposed to do. It can repeat that a lot of times with no damage to itself or to the hydraulic system.

Now if you should somehow manage to get tricky enough to get way too heavy of a load a foot off the ground and set off across the pasture at speed .... and then hit a bump or dip that causes the loader to bounce violently then you could blow some internal seals. It rarely happens but it's possible. Blown seals could even be the O ring type seals in the cylinders. So if that happens, then the usual result is that the won't lift as much and wants higher revs to do it....but it still lifts a bit.


I can't imagine what would cause it to completely quit working other than Slim's stuck relief valve or maybe a sheared pin in the hydraulic pump drive shaft.
The stuck relief valve would cause all the symptoms you are seeing, and depending on how it is stuck it might not make any noise. They are cheap, so start there. You could even try adjusting the spring on the relief valve. Some systems have several relief valves but there is almost always a main one right on the loader control valve.

Just for more info, does your loader have a separate pump or does it use the same pump as the 3pt hitch or power steering? Some tractors have several pumps and others use one large pump. Try the 3pt hitch. See if it works.

The load was never too heavy for the relief valve to bypass, the load was too heavy and awkward for the tractor. Originally it lifted no problem but tractor would start to tip. So I kept it 6 " off the ground and moved it several hundred feet. Then that is when I found it would not lift. Latter that evening the loader seemed to be working, is it possible hydraulic fluid got hot and broke down to the point that it failed? I don't know the history of the tractor, 460 hours, don't know when fluid was changed or if it even had been changed, looks clear amd clean. Tractor does have two pumps.

Hot fluid will not lift as much as cold fluid, but it can be very very hot and still lift OK. Same for dirty. Doubt it's the fluid.
On mine I put a 5000 psi pressure gauge inline with the fluid pressure hose to the loader valve. Right where I can see it. Total cost less than $20. That lets me get an idea of how the system is working.

Kubota is one of the only companies that engineer and manufacture the whole tractor top to bottom, including the engine. They are most certainly not assembling parts as you say. Wheels/tires are the only major parts they sub out. They even make their own loaders and buckets.

Kubota, Yanmar and Iseki (MF GC1700 Series SCUTs) are the only 3 who develop and build complete tractors (engines, hydraulics, transmissions, etc.) that I discovered. Features/specs for dollar, we went with a Massey GC1725M TLB. Even JD uses Yanmar engines and other parts produced by various companies. In the end, I wanted a SCUT that was engineered and built by primarily one company, and it came down to Kubota, Yanmar and the MF GC1700 (Iseki) series.

Just an update. I did buy a kubota. TYM came off the table mainly because the dealer was a guy out of his garage and didnt want to deal with that. Almost bought a kioti but kubota ended up only being 2k more and I got AC in the cab.

FWIW i said to the dealer well at least Kubota is made in the US, he laughed, then I said well at least most of the parts, he laughed again.

Yes, on any given day today it's hard to figure out what tractor manufacturers are emphasizing quality vs. which ones emphasize profit first.

The distinction used to be more obvious, and companies a lot less shy about showing what their goals were.

One way is to go look at & talk to the dealerships. There you can begin to see the company culture. Maybe even get a chance to look around in the service dept. If you do, ask if the company sends their mechanics to factory service school on new models each year. Take a look at the factory service bulletins, manuals, & specialized diagnostic software. There's a lot to be learned in the service dept.

The best way I know of is to patronize companies that make a lot of their own parts in house rather than sending out designs to be made all over the world & assembling the results.
Japanese companies figured that out a long time ago. It's part of what makes their products so consistently high quality.

Frankly I wish I could say the same for US industry. We used to be able to. There must still be some few manufacturers in the US that emphasize quality first, but that type of industrial philosophy doesn't have the backing here it once did.
Luckily for us quality nerds the Japanese are holding on.

Kubota is a Japanese company, same as Yanmar and Iseki. Assembled in the USA is about as good as it gets.
