YM 2620D 4x4 broken?

[winston1]

The YM2610 vs. the YM2620 have different engines.

YM2610 has the same 3T80 as the YM2500 and JD850.

YM2620 has the 3T84 Series engine. It's the most popular engine in the YM series. One could take the YM3110 fuel injector pump and swap it in for more engine power from seeing how the same engine is scalable in Hp by the fuel injector pump.

There could be differences if I recall with dry vs. wet brake system too between the 2 models. In Japan, some tractors were made explicitly for rice fields and others for soil planting. With this said, the controls are setup as Winston pointed out for the applications the tractors would used in.

I did a search last night on the YM2620 and found the RS-1700 tiller ! I've been looking for any images on this tiller because it's part of the YM2610 part manual, but it's alluded everything I tried to find it. The nice thing is, there were a half dozen pixs of the unit. I'm very pleased now. Seems BOTH the YM2610 and YM2620 used this tiller.
All I need now are clear images for the RS1600 or the -01 or -02. There are minor differences and 1 major; 2PT vs. 3PT difference.

Wish there was a tiller understanding to figure out what the ending number meant. Maybe Ernie could answer that. Not sure.

bmaverick, you are correct about different engines. I had run across that before but forgotten. I am thinking in most cases the engines are the same in the 10 or 20 series engines.

Yes, you are correct with the models below the YM2500 using the same engines. This YM2610 & YM2620 tend to be an oddball difference. Why? Not sure. Only Yanmar would know those details.

It would be SUPER to have a model number matrix and understanding what was a common trend and also the uncommon (broke the rules) machines in a listing. I did take the Yahoo Excel matrix document and updated it much. It still has empty cells as info could not be found. I have to give credit to '284 International', 'Scotty Drive' & 'rScotty' for providing enough info for updates to the document in the past year. It's a work in progress.

I'll have to email you the file as Excel files will not attach here.
YANMAR-MODEL-LISTING.xls

There are tabs for the John Deere machines, YM machines, F & FX machines, US machines, and EU machines.

I tend to update this often and upload to the Yanmar Tractor Owners Group on GroupsIO.
