You did a good job on the write up for information regarding the Massey Ferguson MF650 tiller for the MF10 and MF12 garden tractors Doug. :D

Good Job on the article Doug

Thanks for your time on this project. GREAT Article

Just picked up one of those 22" tillers.
Have to let you know what I have when we have it sorted

Great write up! I got both styles of tillers, splined and square drive. But both gear boxes on the tine axle are stripped. I was wondering if anyone has a box or just the gears for in the box. I'd like to show how will they till when I am at the little guys show in Manchester, Pa
Very well written Doug! I know next to nothing about Maseys, but I have a theory about the extra shaft on the newer gearbox. Could it have been for a front PTO shaft to drive a snow blower for instance?
Great article Doug

Sorry for taking so long to get back, 1 month late, the front shaft that comes out of the gear box lines up with the bottom of the front axle and is really close to it, 2" or 3" I think. This is why I don't know what it's for, you couldn't put a drive shaft on it it would hit the front axle

Great info, Doug. I was looking for a rototiller and found a guy that had a Mf garden tractor and I assumed an MF650. He didn't know the size of the garden tractor. He inheritted this setup and had never used them together. The tiller looks complete. The tractor is very rough and I coudn't find any identification on it. I found a model stamp on the engine, HH70, which translates to 7hp, so I assume I have a MF7. In reading this article, it sounds like the MF650 only fits MF10 and MF12. Is there a tiller that fits a MF7? Is there a way to identify the exact tiller I have? Just yesterday a nice MF14 came up for sale reasonably priced. Now I am wondering if this tiller will fit that? I think the MF14 needs a MF550, but am unsure.
To summarize:
1) How do identify the model of my tiller
2) What tiller models fit what garden tractor models? MF7/8 - ???, MF10/12 - MF650, MF14 - MF550

Thanks in advance for your responses. If the tiller I have fits the MF14, I need to move quickly to purchase it

There is no tractor driven tiller for the MF7s, 8s, you should be able to modify ans use a self powered tow behind though.
If the tiller you have looks like the ones in this article, shaft driven then it's a MF650, some are wider, used on MF10s, 12s.
MF550 is belt driven fits MF14, 16s
Whatever you buy make sure it has everything you need to hook it up and make it work

Thanks for the info!

Well, then it definitely is the MF650 and it is complete. The only piece maybe missing is the extension, but it sounds like that is not necessary. I got looking at this tractor a little closer. I don't think it is a MF7 even though it may have the 7hp on it. I think this is really a MF10/12. This tractor and it's parts mower are in ROUGH, but solid shape. No other identification. I think it was a decent deal though. 2 tractors, but only one with a motor. Wheel weights, dozer blade, and tiller for $200. The spare tractor has a slightly different front end. It looks like a dynamark front end. It very well could be based on the production history of these machines. Also, it looks like maybe it was once painted blue. I am wondering if the old 7hp can handle a tiller? I will try to post a picture soon. No laughing.

When trying to do some research I came across I think another good deal. I am trying to figure out how to buy this without the wife freaking out. MF14 original owner with dozer, snowthrower, and deck for $800 in good shape. Does this sound good? Sounds like finding a MF550 is next to impossible. I am really only needing something with a tiller that is usable and this is the mess I am getting myself in. This stuff is fun!

I don't think you will find the 7hp sufficient enough for a tiller, it might work but you will definitely have to watch how deep you go with each pass. That would be a good deal on the MF14. The addiction won't stop there either LOL
I need to replace the pulley on this gearbox. Any ideas on what replaces this and where to get it? Thanks!
I believe it's a 4" pulley, just find a 4" pulley that fits the shaft and it should work

Thanks, Doug!

Happy Easter everyone!

I finally was able to spend a little time today hooking up the tiller. I drilled out and mounted the lift spring bracket. Then I removed the mower deck and attached the tiller. I found out why everyone has a different tractor for each implement. :smilewink: This was more of a bear than I expected. It really wasn't too bad, but I had to attach the tiller all at once. When I bought this, the Drive shaft was already connected to the gear box and tiller. I read that these should be connected to each other via a shoulder bolt, but on mine there was some sort of pin. I was unable to tap out this pin and didn't want to break anything. It obviously is in there good as no one would ever want to attach, dettach, or store it as one piece. I think it would have been much simpler to mount in 3 pieces than it was in 1 piece. Lugging around 140lbs to line up and mount bolts was harder than it should have been. But I had fun and got it all ready to go. Well, all but one thing....

I bought this Gates#2360. This is a 36" belt. I didn't try to actually run it, but I am really don't think this could be the correct belt. It has to be at least 2 inches too long. (And yes I checked this with the PTO in the engaged position. In the disengaged position the belt could fall off). So I was bummed to not be able to check this out. It's probably too wet anyway. Doug, can you or someone else verify the size or id of this belt? It is not in the manual.

I did want to pass along good find. When I called a local auto parts store to purchase this gates belt, they wanted $25. I thought that was steep, so I purchased their cheap throw-away one for $5 and then looked on the internet for the gates. I found both KSCdirect .com and vbeltsupply .com were very cheap. This belt was under $6 on each site. I also needed a big deck belt (123") for my john deere that was $80. On these websites they had a kevlar belt (not JD) for about $20. I was suspicious, but decided to give them a try. Shipping was a little high, at $13, but worth it. I bought from kscdirect, and choose the cheapest shipping method and still received the gates belt in 1 day. I have not yet received the john deere belt, but I called and they said it was coming from another location.

Also, Doug, I see this in your article:

I didn't notice that until now and I mounted this in the lowest position. I don't see this in the manual. How did you figure this out? Do you think I need to move these up? Everything seems to pivot just fine when I raise and lower the tiller via the lift lever.

Thanks!

The drive shaft to front gear box, whether you have a bolt or some sort of pin shouldn't make a difference as long as the pin doesn't fall out.

I'm 90% the belt sizes I listed are right, I don't have my tiller on the tractor right now but it is soon to go on and I will check and get back to you on it.
A34, or 4L360, I crossed the #s over to get the gates #.
I just use universal type belts, just match up the width and length.

As for the hole position to mount on the tractor, 1 of my tillers has a sticker on it says to mount to middle hole.

Thanks.
Yeah, I just was unable to remove this pin. I didn't want to break anything.

The throw-away belt I got is a 4L360. Both it and the gates have the same dimensions and length of 36-5/8". If just seems way too long.

I see the sticker in the picture now in regards to using the middle hole. Thanks for pointing that out

What a great article!!! Thanks for sharing this valuable information with us!! Now all I have to do is find a tiller. Thanks again.
do you have a manual for the MF650 tiller?
or for a mf10 tractor?

I have a 650 tiller as well
I don't know Gates numbering system but 3L, 4L, 5L reference the width in eighths of an inch. 3L = 3/8". 360 means it's a 36" long belt. I'm sure most everybody knows this already. I sold car parts from 15 until graduating college. I have tons of useless part numbers in my head from Chevy small block points and condensers to Ford big block oil filters, but I can't remember what I had for lunch yesterday.....

I am trying to find the lift assist springs for the 38" tiller right mow and i also want to know what size springs those are
I just picked up a 38" wide in decent shape, just a lot of surface rust. The PO only had one of the three lift assist springs but it is too far rusted. Roughly 4.5" long and 2.5" wide is the size, with bolts in the center that go through the pipe for adjusting. I doubt that I can find springs like that, I will tinker around with different springs and possible eye bolts to see what I can do.
This is a very interesting article about the mf tiller. Thanks for posting it.
