I just acquired a mf 12 but there are a couple things I'm uncertain of. I apologize in advance, I'm sure these are super basic questions.
1: the steering is very sloppy and the steering wheel doesn't seat in its hole
2: the engine is a kohler, were some of these fitted with this motor from the factory?
3: it has the turf tires and I need some more traction when using the plow so should I put the tractor style tires on it or would that leave ruts when mowing? I have the trailer also so could I put the tractor tires on those rims and swap when traction is needed?
4: I have the tiller attachment also but I don't know how the torque converter box mounts to the tractor. Do I remove a pulley? I've looked at the manual but it's still unclear.
5: I have a 16" or so bar that came with it that I don't know what it does, and also a large metal piece, triangular, that I don't know where it goes either. It has two bolts that are the same distance apart as the bolt holes on the front metal plate next to the release tab/spring.

Sorry I have so many questions. Any help would be very appreciated!

Andy, Welcome to the forum. We have a lot of good Massey guys here and I'm sure they wil be along to help you. One thing I'll warn you is they'll want pictures. This will help see what you are asking about.

1 - Not sure what you mean by doesn't seat in it's hole? Maybe the splines on the wheel or the top of the steering shaft is damaged? There are a lot of wear points on the steering system. If you want to tighten it up, expect to replace all of the ball joints on the tractor and rebuild the steering box.

2 - The original eninge in the MF 10 and 12 was a Tecumseh, the 14 and 16 had Kohlers. If yours has a Kohler it's either a refit, or not a 12.

3 - Ag tires could potentially be harder on your lawn, but the rear ends in these tractors are fully open and not locked at all, so you should be OK. I have no idea what tires or wheels are on your trailer, none of the MF trailers had large enough wheels to swap with the rears on a 12. The OEM size would be 23x8.50x12 on the rear and 16x6.50x8 on the front.

4 - Have you looked at the owners manual for the tiller? Your's might have the jackshaft for the mower still installed, and I THINK that has to be removed. I have not had a chance to install my tiller, only removed it. So I don't know.

5 - Not sure on the metal bar. Pictures would help a lot in this case. Same with the trianguar piece. Initial thoughts would be a belt guard that attaches to the foot pedal? But would need pics for a better answer. At the very least you could have a look though the parts diagrams on Agcopartsbooks.com and see if you can find it.

Thanks for the responses. I will take some pics of everything I have questions about and post them.
Sorry for such vague questions.

I just tried removing the mower drive shaft and pulleys but it's not wanting to come off. I can see that I will need to remove the spring attached to this shaft but I'm afraid that'll be really hard to put back on just in case this isn't what I'm supposed to take off.
Anyway, I took some pics to better explain but I guess I haven't been a member long enough. The link I clicked just said "locked". Anyone know how long it takes before I can upload? Sorry again for all the annoying questions, but I truly appreciate the help

Locked just refers to the fact that no one can reply on the post. You should still be able to view the video but it may take a while to come up. If you use the "more reply options" at the bottom, it takes you to a page where you can choose pictures from your computer and put them on the page. then put your cursor where you want the picture in the message and click "add to post" behind each picture

Ok sorry about that, I guess you have to be on a computer rather than phone to attach files. Here is my current configuration. It sounds to me like you're saying I need to take both pulleys and shaft that go to the mower deck attachment in order to mount the gear box for the tiller. I tried this Friday but it didn't seem right. I guess this spring that attaches to the shaft must come off as well. The reason I hesitated was that the spring is under a lot of tension and was afraid of not being able to get it back on.

Also I included pics of my current real tire. The ones on the trailer seem to be the same size and I believe they also are Massey Ferguson wheels since they are the 4 spoke with square hole just like the tractor. They are just skinnier. No big rush there.

The other pic is the steering wheel where it attaches to the column coming out of the dash. I'm sure there's an adjustment from below that can get the wheel to seat or it's supposed to. Sorry for such a random post with multiple questions/problems. I will try and be more organized and concise in the future. Thanks for all of your patience and help with this tractor and this forum! I am very impressed with the amount of prompt help here.

Yes, spring and pulley assembly does come off to mount tiller box. (Check oil in box before mounting it)
(Separate Pedal, spring and pulley assembly stays)
Steering wheel, there should be a rubber grommet around that shaft to keep it centered. Slop there is not intentional.

As for the wheels, we would need a pic or two of the cart and wheels. I don't think they had a 12" wheel on their trailers, but maybe it's modified or built?

That pulley assembly comes off with a bolt, but you do have to remove one pulley to get the ing off (from memory) the inside one?

That mule drive is a son of a gun to get off sometimes, don't lose your patience.
One of the reasons I have started thinking a "tractor for each implement"

Is the mule drive the "torque converter" or square red box with the pulley attached? I have that attached to the mower deck and I have another one that goes with the drive shaft for the tiller... I'm guessing this is something else. So I take the nut off the inner pulley I have the pic of and only take the inner pulley off? That makes sense. There is a hole on the other box, does this pivot on something? Here are some additional pics. I'm pretty sure I now understand how it goes since only the inner pulley comes off but just want to confirm with you guys. The only part I'm concerned with is where the drive mounts to the tractor. Also, here are a couple of wheel pics. Black is trailer (obviously). Thanks again!!!!!

ok I dl'd the tiller manual from this forum and it sure looks like the gear box for the tiller mounts through the same hole that the shaft with both pulleys is currently at. When I took the bolt on the current pulley shaft out it was a 9/16" bolt/nut. The bolt that holds the tiller gear box on is quite large so I'm not sure this is correct. So does the entire shaft and both pulleys come off to mount the tiller gear box? If so, that large spring attaching from the front of the tractor frame to the shaft would also have to come off. I think I'll wait to be sure of everything before I attempt this. The other attachments were so easy to put on and off that it seems this would be the same. Thanks again and I'm really sorry to blow up this thread

Just so I'm explaining myself correctly. This is the shaft that I am thinking I would need to take off. You can see the spring attached to the middle and the gear box for the tiller is just hanging on the pin behind it. This pic is looking from underneath front to back

Yes, the spring has to come off first, and the S-piece with it. Then remove the inner pulley to get to the nut/bolt holding the mule drive in place, undo that and slide out the bolt and sleeve and remove the whole assembly.

The tiller gearbox goes on loosely until everything has been connected up, then you can tighten the larger bolt.

The spring can be awkward, I use a length of twine looped through the end and pull on that with one foot while slipping off the S-piece.

This is the way. :iagree:
You do need to remove the mule drive / pulley assembly / pulley-spring-tube-shaft-thing, whatever you call it... The thing outlined in Redish pink Automotive tire Vehicle Tire Wheel Automotive design

You will want to read the manual and figure out which tiller version you have and what it was on last. Pics can help us help you there. The tube on the input to the tiller will have an extension if on a 12 Hydro, they are a couple of inches longer.

Some pictures of mine. Hope they help. The triangle part is for the snow plow so it doesn't move side to side when using. I hope thats right. Noel

Oh yeah, if the right wheel turns too far to the right, this is what can happen to your tire. Hit some thing and tire turned on me into the pulley. May not happen with all tractors or type of tire you have on. Just my opinion.
