TYM T494H or Yanmar YT347

[Sawyer Rob]

The Kukje is a Cummins A series with a couple small changes. Cummins sold them the rights. The A series was originally made by Onan, then Cummins bought it. Some people will argue that it's not a real Cummins engine, but they seem to be pretty reliable so it kinda does not matter.

I believe that engine was "originally" a Kohler design, then handed down and had design changes along the way.

It originally was a "wet sleeve" engine and it's too bad they didn't keep that design!

This is what I found on kukje:

Kukje was founded in 1968 as Korea Agricultural Machinery Co., and changed its name in 1978 to Kukje Machinery Co. In 1980, Kukje signed a technological agreement with Yanmar of Japan. In addition, Kukje has manufactured/distributed some John Deere tractors since 1987.

Interestingly enough that link is the dealer I was talking to that no longer are carrying the TYM line due to lack of TYM customer/parts support....at least for the time being.

Yanmar USA. being local to me here in Ga.. And rumor has it Yanmar sales are doing extremely well. My guess the TYM., Cub cudet etc. will still have Parts Available but are focusing more on a direct line of Yanmar tractors and now Equipment. The line of ATV. is starting to rank up there with the tractors. Very nice!

Interestingly enough, TYM just opened a big new campus in Bloomsburg, where they plan to store parts, tractors, service training and more.

They also announced some sort of partnership with Yanmar a couple months back where they would supply tractors to Yanmar.

And some sort of partnership with Iseki as well.

Yanmar does makes good tractors, no doubt, but I feel their main focus is more towards construction equipment rather than agricultural equipment. In my country, we have access to amount of tractors sold per brand and their most popular sold model. With Yanmar, I can count with all my 25 fingers the amount of tractors they sold in a year.

Regarding TYM? I'm more fond of the former Branson built models. Just overall better built, heavier duty build all around, sturdier controls, and more. What will happen in the future with these models after TYM merging? I don't know. At one point they will release new tractors, probably combining the best of both brands.

I really like the YT series and may in fact buy one but One thing I don't like is that they are normally aspirated ( as is the T494 from what I could find). I am only at 3500 ft and would probably see a 10% power loss, at 7000 it would likely be double)
A turbo loses about 1% per thousand, NA about 3%.
If my numbers are wrong, someone please correct me.

I also would look at the ex-Branson tractors- the xx20 series. Along with the build they have a 4 range transmission which folks seem to love. They are supposed to be a tiny bit more austere. I have read that a regen helps in cold climates.The comparable one to the T494 is the 4820, which is also NA. Moving up to the 5520 gets you a turbo.

Just for fun I did some quick and dirty math using 1%/1000 loss and 3%/1000 loss.

T494 pto hp 37.2 becomes 29 at 7000ft
4820 pto hp 38.4 becomes 30 at 7000ft
5520 pto hp 44 becomes 41 at 7000ft

The comparable one to the T494 is the 4820, which is also NA. Moving up to the 5520 gets you a turbo.

The Branson 4815 is closer to the T474 than the 4820 is, the 4820 is more comparable to the T494 and the 5520 is closer to the T574. All have the same engine with the 5520 and T754 being the turbo version. The xx20 series and T5xx series are the heavier 6' wide chassis while the xx15 and T574/494 series are the smaller lighter 5' wide chassis (number approximate there..). The T494 and T574 share a lot of the front end with the T474 but they made it wider so there's a lot more leverage on it and the wheels on that T series are held on with just a circ clip, a number of the T494/T574 machines seem to have lost their front wheels while in operation as a result. The xx15 and xx20 machines use actual nuts to hold things together and don't seem to have the same failures.

The most common complaint I've seen on all of these is sloppy assembly, tighten everything and maybe add a little blue locktite. Some of the components are annoying on the xx20 (the pin on the loader seems to interfere with the hydraulics so a lot of folks either pull the grab handle off or replace the pin with a shoulder bolt & nut). Overall I have seen very few complains on the xx20's after some months of reading on them.

Tym does seem to be making a decent push into the US market. I admit to being a touch concerned about Yanmar's commitment (past performance no indication of future .. so fingers crossed.. they are nice machines). Years ago I had a grey market YM1500D and it was a very nice little machine, the older ones I reckon have a lot of historical parts availability just because so many grey market ones came in.

I have a 5520H on order to compliment my "big lawn mower" tractor (a little B2601), time will tell if that was a wise decision or not. I had a line on a moderately used L4740 that I'm still second guessing myself if I should have bought instead but I go skeeze vibes from the seller so.. I also priced out a new MX5400 and... yikes... In some ways the Branson is actually a nicer tractor (in how it's outfitted) compared to the MX, and the rear end actually looked beefier, the proof is of course in the pudding (and material quality and weld and fitment... which I won't know for sure until I've had more time on the machine).

I think you are confused. I have a T574 and studied these in some detail. The T494 and 4820 are the non-turbo versions of the T574 and 5520.

The T474 is closer to the 15 series. Focus on the weight of the machines. The T494/574 have a larger front end than the T474. They have similar design, but not the same.

Go to TYM website. The 474/15 models are series 2.

The 494/574/xx20 models are series 3.

The T754 is series 4 and uses a Deutz engine. Significantly bigger than the T574/5520.

The 474, 494, 4820, 5520 and 574 all use basically the same engine. 48HP non-turbo or the 55 HP turbo version.

No T595 exists.

The xx20 is a little heavier duty, but has fewer features standard than the T494/574. Both are great tractors.

I've read some postings citing dealers dropping TYM due to warranty support and parts avail.
Are these major concerns or just local issues?
Anybody heard anything about turbos coming to the YT series?

Thanks

Hadn’t heard anything about Yanmar moving towards turbo’s. Looks like they make power the old fashioned way with displacement. However, the Yanmar engines in quite a few John Deere’s are turbocharged. Go figure.
