Buying Advice Considering a YM2000 purchase

[deepNdirt]

Hi deepNdirt

Is the "overun clutch" you refer to - the same as the overun coupler?

I can see how the terminology could be questionable, However what I am talking about is the ratchet (Overrun clutch), I believe the coupler is the one that adapts one type of spline to another,

Note: the picture showing the PTO overrun clutch on top, the adapter coupler on the bottom,

and also if you are buying a package deal from Fredricks they will be sure the drive shafts are to the correct lengths and ready to go, Although don't be surprised if buying either one of these implements elsewhere you might find yourself having to size the shafts yourself, ( meaning ) cutting them down to fit your tractor,
I did on both of the 4 ft Brush cutters I've owned anyway,

284.... the 186d is 18hp.

The Japanese market machines are numbered according to PTO horsepower. The 186 has 18 engine horsepower and the PTO horsepower is 15. The Japanese market version of the 186 is the 1510. The YM2000 in US garb (YM240) is 24 engine and 20 PTO horsepower.

I should have specified what i meant more accurately. Thanks.

Hi kenmac

Yes, I'm considering their 5' ft finish mower, and 4'ft. brush hog.

I wouldn't consider a light duty cutter. med duty or heavy duty. If they still LMC brand cutters, they are made right up the road from them

I think we're all talking about the same thing here but 'overrun coupler' is confusing. 'Overrun ratchet' would be more precise but 'overrun clutch' seems to be the industry standard name for the device. At any rate it looks like deepNdirt's first picture and has the same function as 'coast' on a bicycle. It prevents the inertia of the mower from pushing the tractor forward.

Adding a Quick Hitch might move the mower back the same distance as the overrun clutch adds to the driveline length which would avoid cutting anything. But check all this carefully - you can damage the tractor's pto when you lift the mower if the driveline is too long.

I didn't notice if you specified whether you are already familiar with YM2000, or a true beginner like most of us started out. YM240 was the US version of YM2000 and its documentation is what you will want (unless you can read Japanese). You might like to look at the YM240 sales brochure etc linked from my sig at the bottom of this post.


Edit: Bah. I didn't highlight 'quick hitch' above, that's an unwanted 'site feature'. I'm not talking about that at all, I'm talking about this. (plus the special top connector that comes with Tractor Supply's version of the QH, or is telephone special order from HF). Although I suppose the Pat's accessory could work too. As for me, I like the added rear ballast that a Quick Hitch provides.

Bah again. Now I see quick hitch above isn't highlighted any more. At least for me.

These are originally rScotty's for the 186 brochure, and California's for the 240 brochure (What he has linked). I tried to add them to my earlier post, but couldn't upload them to TBN.

Thanks 284 for posting the spec sheets......I haven't seen those specific sheets before. Good information. :thumbsup::thumbsup:

Thanks deepNdirt! I contacted Fredricks and they've confirmed that all of their Yanmars are sold with the overrun clutch - I was Glad to hear that!:thumbsup:

kenmac:

Since I'm a newbe....a few dumb questions: Are the implements rated as light, medium, and heavy? Or do you just look at the overall construction/price to arrive at this?

Thanks for the info California.

Yes, I'm a newbe here and this YM 2000 will be my first utlitity tractor. I like the quick hitch method that you refrenced - I will now start to do some research on this.

Also, would like to get my hands on the owners/operators manual, and a repair manual on the YM240...as I'm sure I'll need this down the road.:thumbsup:

I would be surprised if Fredrick's doesn't supply an operator's manual. They likely sell the service manuals, too, but they are also available from a site sponsor here, Hoye tractor, LMTC, or from online auctions.

I don't know anything about the specific brands, but it's nice to find something that is popular and/or uses generic parts. For instance, Agrisupply sells rotary cutter gearboxes in an array of sizes and shaft types: Agri Supply - Search

If your cutter uses one of those styles, it will always be simple, in the unlikely event of a gearbox failure, to source a replacement, drop-in box that is compatible with your current PTO shaft and so forth. Similarly, they sell a variety of replacement blades. Buying a unit that is cross-compatible with other units is a wise decision, in my view.

Having the same blade form, length, and bolt hole size and pattern means if something goes wrong, you can find a replacement part easily. Rough mowers are not nearly as fragile as finish mowers, but still suffer from eventual blade damage in rough use.

If you get a box blade, the thicker and heavier the metal the better. I've never seen a box blade built too heavy. They may be too big for a compact tractor, but not too heavy. I always end up adding ballast anyway, usually in the form of suitcase weights, so any extra sturdiness or mass is always appreciated.
