Yanmar - Model Cover Pages

The other Tractor from Spalding was a YM2500. I liked it! Fell right in size wise in between the 2000 and the JD. 5103. Wasn't or didn't care for the PTO. at all on the 2500 which I was told could be changed rather easily. Was worried with It belonging to my church and people not knowing how easy it was to shift into the wrong gear. They found a guy to keep up with it and never heard any problems but 1 time. Small Hyd. leak. Steve asked me to see if I could check it out which I asked my son to drive me over. Looked as though the Hyd. Lock was turned and left on and may have tried to lift the mower. No big deal just tightened the line at the pump and it quit. I think the JD 850 was just 1 gear PTO @ 540. And of course this one was UTDA.. Which is just the way he likes it apparently.

YM2610

Why a long pause since the last model? Well, it's sort of hard not to be very bias on the model one owns and loves.

With the YM2500 just mentioned, why wasn't this next model called a YM2510 instead? They both have the same 3T80 engine and both are related to the JD850, JD900HC and JD750 with the same 3T80 base engine construction.

Keep in mind there is no YM2600 either. There is a void of sorts created purposely by Yanmar.

Here's a UTDA YM2610 on the lot.

Here's a UTDA YM2610 in my yard. (Wait, they are both the same machine. )

OK, I got my Fandom out of the way.

Like the YM2500, the Tach and PTO multi-speed gauge is very much the same.

The dash and controls are very basic.

Like a few other YM models, both US import and gray market, the YM2610 can use the fuel gauge with cap arrangement.

A YM2610 and a JD850 both UTDA restored.

Both the YM2500 gear and the YM2610 PowerShift share enough components with the John Deere 50 Series for parts availability, modifications, and attachments. A FEL from the JD850 or JD950 would fit like a glove. The John Deere service and parts manuals are all in English and other languages making these tractors easy to figure out.

The tractors made on the same production lines in Japan.

YM2620

It's a tad of an upgrade over the YM2610.

Models ending in -20 were often with a wet brake rear system. Adjusts were a bit easier unless moisture got into the drums and a bit of rust happens.

The YM2620 has one of the popular engine series, the 3T84. The 3T84-NC exactly.
This engine series is seen throughout the YM US & UK domestic machines and in the wonderful Gray Market machines. This offers more parts and options.

Like the YM2610, the YM2620 comes with the PowerShift. Likewise the -10 & -20 share the same engine panels, hood, fenders and other body parts. However, the grill is different, usually a black-charcoal gray and the floor boards are wider and broader in length.

From this stance, it's hard to notice if this is a YM2500, YM2610, YM2620 or a YM2820.

When the engine side panels are on, then it becomes a bit harder as with this UTDA restored model.

With the -20 models, the dash and gauges are more modern than the -00 and -10 models.

As made by Yanmar with all the panels even around the seating. Likewise, between the two images, it does have the same multi-speed PTO as the YM2610.

With the panels removed, it has the making of the YM2500 & YM2610.

It's hard to if this was a model with 'draft' control for 3PT attachments. I do see the lever next to the 3PT lift lever like the Yanmar made John Deere 50/55-Series.

Behind the seat is a rear wall. Great for a toolbox or ability to have an enclosed cab.

YM2700

The YM2700 is the bigger sibling to the YM2200. It's the last of the models ending in -00 with a 2-cly engine. As mentioned before the YM2500 broke the ranks with a 3-cly engine.

The YM2200 engine is the 2TR22
The YM2700 engine is the 2TR27

The YM2200, YM2700, YM2700I, YM2700L and YM2700R share a slew of parts from Yanmar's earlier YM 3-digit models sold only in Japan. These are the YM176, YM177 and YM273. The Parts Manual does show the YM273 being nearly the base of both models.

The looks of the two models are nearly identical.

These models have strange attributes from it's YM273 parent. To drain the hydraulics, there is a top drain and a bottom drain. These must be emptied first before pull the cover off with the suction line before getting to the filter.

YM2820

Much like it's sibling, the YM2620, the YM2820 has a mere 2Hp more. No other models are to be had between these two numbers. Missing are models in the YM2801, YM2802, and YM2810. For some reasoning Yanmar just skips ahead with fewer offerings.

Fredrick's lists the YM2820 as a rare machine, being it's harder to find even in Japan. Low production run of this model with many neat features. The engine is the widely used 3T84 found also in the YM3000, YM3110 and YM3220. What is interesting with this engine, the YM3810 and the YM3000R has the same 3T84 engine with a turbo. Reading some of the tractor forums in Asia and the EU, people would slap on a turbo to their lower model Yanmars with the 3T84 engines.

Since the YM2820 is a rare machine, the body style relates to the YM2620 and the engine like the YM3000 without the turbo. Being rare, it's a bit of a challenge finding images of this certain model.

We'll start off with a very clean looking YM2820 as a UTDA restored machine.

A really nice one from the eastern EU with it's original tiller.

Floor controls are just a grab near your feet.

The dash is very plush with 6 symbol indicator lamps, temp gauge,
fuel gauge, and rpm gauge. The PowerShift is up on the column. This makes for an spacious open cab to walk thru either side.

These models typically came with Power Steering.

The 3PT controls and draft controls were standard equipment.

Like many of the YMxx10 & YMxx20 models, the 4 position multi-select PTO controls are standard as well. At a constant RPM, the PTO speeds would increase in value per the machine specification in the Parts Manual, However, if used in combination of various RPM speeds, one can hit the 500/540 RPMs in any of the selections, thus at high engine RPMS or banding down to lower RPMs to save on fuel, reduce engine wear and reduced noise.

Since the Part Manual hasn't been found ... yet, please refer to the YM2620 for functionality and to the YM3000 without turbo for the engine Parts Manual of the 3T84 in the model ahead.

Up till now, the attached PDFs with most of the YM Gray models listed have parts diagrams and part numbered charts. The trouble is, other than numbers to reference the balloon callouts to find the part number, the rest seems a bit unknown, that is until now.

The Parts Manual Rosetta Stone has been located. It is simply this.

There are still a few more models to cover coming up.

YM3000

This model breaks tradition in the Yanmar model number system. It's the second model ending in -00 to have a 3-cylinder engine, just like it's related YM2500.

What's so special about the 3T84 engine? Well, it has US domestic models with the same engine.

When did the YM3000 arrive on the scene? It was an early bird.

Here is a nice UTDA Fredricks restored model of how this machine looked in it's day.

The YM3000 came in an options package as well. The YM3000R. To some, they thought it meant the machine was a tractor-pull event machine or even a tractor racer. We can see Robin with his YM3000R model.

It took several months to understand that the R after any YM model was indeed not a racer machine. Upon research in the Yanmar Tiller manuals, the R simple meant the machine had all the options to work in the rice paddy fields. Thus one could say, they own a Japan Ricer machine. Back in the 1980s, as Japan vehicle imports hit North America, people called those small cars, rice burners. Funny how the pun can be applied here.

The YM3000 model is greatly admired in Vietnam. There are many instances of seeing these machines in action on video sharing sites.

A nice one out of Poland.

I think 3T84 engine (YM3000) is based on the two cylinder YM2000 or YM2210 engine with another cylinder, no?

When looking at the Parts Manuals, matching the cylinder diameter size from one engine to another will show this.
Yanmar engineering thought thru all of this ahead of time. Likewise those engine rebuilt kits are somewhat universal with gaskets that align to a few engine variants easily.

The YM2500 & YM3000 Parts Manual really shows how the 3T80 and 3T84 shares many parts. Likewise, those 3T72 and 3T75 engines are likely the same way.

Recently, many of us understood that the YM 4-digit series brought over to North America is considered Gray Market. However, there is indeed a twist. A website down under in Australia shows a few of the YM 4-digit machines as true imports from Japan and sold that way.

One example, the YM3000 came with the normal 3T84, then there was a YM3000T with the 3T84T TURBO engine. The Parts Manual is all in English and includes the YM330DT with TURBO as well. See below.

Likewise there is a YM4300 imported to the English world too.

I was surprised to find a YM500 with the 3T95 engine as well.

Down Under got the special treats from Yanmar.
