Need help with a Yanmar 1300

[Paulboyrenishaw]

Good evening

Have just joined this forum after buying a Yanmar 1300 compact with a yanmar 1000 rotovator, it decent nick and at a decent price.

Not this machine doesnt have linkage from what the guy was saying, which is fine i can get hold of that for a relatively cheap price as i want to buy a single furrow plough

However i need to work out how to detach the powered rotovator from the tractor as the connection looks complicated and i cant work out where i need to undo it.
It looks like its connected straight to the machine, the is no exterior drive shaft (if that makes sense)

I have one picture which doesnt really show the setup that well

However the setup is NOT like this https://www.google.co.uk/search?q=ya...80;640;480 it seems like quite a close connection

If anyone can see what i need to do or please let me know, otherwise i can take another pic

Ive just seen another picture of the attachement which is here: https://www.google.co.uk/search?q=ya...3;1000;750

Now once ive detached this , is the a plate of something i need to put over the box thing when the four bolts are removed?

The setup on your YM1300 is actually quite simple, though it is a bit of a pain to attach compared to a traditional 3 point attachment. There are 4 studs on the back of the tractor around the PTO output shaft. The tiller has an articulation that allows it to pivot up and down, and a female PTO connector inside a more or less square box that makes up one side of that joint.

Remove the 4 nuts holding that box onto the tractor, and the lifting links. Then pull on the implement and it will eventually slide off the studs and PTO shaft. It can be fairly difficult to remove; it has probably been on there for 30 years or more. Just be careful, as the implement needs to be forced off all at once, but it's not a bad system really: It produces an extremely compact unit of tractor and tiller, so is very user friendly.

Thank you 284 , that is a very straight forward and easy to understand reply. Have got some one with some long bars (socket set) to undo the nuts!. It looks like it has some new nuts and threads

Am thinking would it be good idea to raise the tiller place it on two pallets, undo the nuts, links etc and then drive the tractor forward, does that sound like a good idea?

Is the any risk of doing this?, or when it comes to reconnect it ?, i understand it may be hard to undo the unit as you say it certainly looks like it has been attached for a long time. I assume the PTO shaft inside will then need undoing?

Have been looking for second hand attachments, but they dont seem to be easy to come by here in the UK. Used the machine today on untouched ground and it really went through. Impressed with it!

Yours may very well come apart more easily; mine would not have come apart had I not tethered it to something solid the first time. The tiller isn't extremely heavy. You could probably lift one side of it at a time onto a pallet to keep it off the ground once it is removed.

I'm not trying to frighten you off from removing it, but mine is markedly harder to connect than a conventional 3 point tiller, mostly because the splined connections have to match up, but rolling the tiller back and forth also spins the the shaft, so it can be annoying to connect.

The PTO shaft doesn't have any retaining device. It simply slips into the female portion, and the entire apparatus is located and retained by the 4 studs.

You know your needs best, but especially with the tractor being 2 wheel drive, I am not convinced you will be happy trying to use a real plow. I don't know any UK store brands, but you may have some success buying and adapting a garden tractor sleeve hitch type plow: Sears.com

I envision a modified drawbar on your tractor with a sleeve hitch on the other end. Lift chains or links should be straightforward to adapt. The YM1300 is very light and lacks traction compared to even tractors a half step bigger or 4 wheel drive, but it will far outdo a garden tractor built on a lawn mower chassis. It is difficult to find implements that are properly matched.

Thats a shame, although from what i had read this tractor is at the bottom end of the power scale for use with a plough.
COMPACT TRACTOR SINGLE FURROW PLOUGH | eBay is what i had in mind (similar to yours)

However may rethink the plough idea as you say it is a light tractor!, however rotovator will have to come off for storage into a shed

You may have saved me some money

Not much to add, just wanted to say hi! Nice to see another small Yanmar, especially in the north of England.

If you do fit a three point hitch, id be interested to see how you attach the lower arms as I don't think the mounting bracket will be there. Mine were attached in a wholly inadequate manner by the seller. I ended up teaching myself to weld so I could make my own lower link bracket.

Also, if you discover any parts suppliers I'd be grateful of the details.

Hens Teeth come to mind talking about parts/equipment for this tractor

Service items are ok, you just need to spend a bit of time cross referencing filters. Most other things are impossible to find this side of the Atlantic.

"Used the machine today on untouched ground and it really went through. Impressed with it!'

That will not be the case with any type of plow on your 2wd ultra-compact. They are just too light to get traction, and if you manage to find traction the front end will be off the ground. I would stick with the rotovator.

Good advice.

Where these things come from, the little ones are basically just portable horsepower for turning a rice paddy tiller. Stick with the rototiller for cultivation.

If you really want a 3-point kit for the back to run standard Category 1 implements, Hoyetractor dot com in Texas has the kit. But shipping and tariff costs to UK might be prohibitive. Is a similar kit available to buy over there?

Seems to me the kit salvaged off any junked small tractor could be adapted if you can find it. All 3-point fittings are pretty much standardized and interchangeable within each Category (size). You would probably want to cut and shorten the horizontal arms and the uprights.

Or use this 1300 for tilling and buy a larger Yanmar for implements. Don't ask how I know that. (click on my sig link, below).

I think i am going to take peoples advice and not bother with the plough!!
However managed to get the rotovator off nice and easily Luckily Partners dad has a garage so brought a lot of tools along and in the end it came of really well

thanks again 284 for your detailed advice

You're very welcome, and I hope your tractor provides long and useful service to you.

If any plow is going to work on that tractor, the one you linked to very well may be the one. It is an 8" plow, but appears to be well built and sturdy, and has enough mass to probably work, and the coulter will help, too. It will be much better than the Sears product I linked to earlier. However, as was mentioned, these tractors are really designed to power the tiller and transport it. If your conditions are suited to plowing, though, it may be a good match.

You may already know about them, but there is a Belgian company providing compact tractor parts for the EU. They are known for producing PTO reversers for the few non-standard rotation compact machines, but also have many other products on their website. I know nothing about them except what I have shared. Your online store for Kubota, Iseki, and Yanmar micro tractor spare parts and manuals.

They do offer conventional lift arms, top and side link kits, etc for these types of machines, but you will probably need to fabricate or find a top plate to use as a tractor side top link bracket.

You may decide that by the time you are 425-odd pounds into adapting the tractor and buying a plow, it's not worth it, but you are the only one who could make that decision. Let us know how your projects go!
