Driveshaft for a Yanmar Tiller

Anonymous Poster · May 31, 2003

I decided to hook up my tiller for the first time this year, well first ever, and when I started to hook the driveshaft to it, it seemed to long. Can anyone tell if the driveshaft is to long or do I have the tiller attached to the 3 point hitch wrong? I can take more pictures tomorrow if need be.

Take the OR clutch off. It wasn't designed to have that on.

Yep, he's right, you don't need the overrunning clutch to run the tiller. Man I wish that I had a 3 point hitch for my tiller. Sure would make it easier to switch from my bush hog to the tiller. Have fun /forums/images/graemlins/cool.gif

Thanks Reed and Hondo, the OR was the problem. I dont know what I would do without this board /forums/images/graemlins/grin.gif

Get rid of the overrunning clutch. Also you may find that you will need to attach the PTO shaft first before attaching the 3pt hardware. The tillers set very close to the real wheels that getting a saft on after attachment may not be possible.

Gary,
Thats what I had to do is attach the shaft first and then the 3 point hardware. I also found out that I couldnt till and turn the tractor at the same time because while in a turn the rear tires would come in contact with the front lip of the tiller. I guess this is normal.

GHog,
Have you had any trouble aligning the to tiller shafts? Mine is very difficult to connect together. bw

Brett,

thought I'd poke my nose in here, I just got a tiller a few weeks ago and to slide the PTO shaft into place I had to clean many years of crud off the splines. A little dab of grease and it was cool.

Also make sure the shaft extends in and out smoothly. It may need a little cleaning and greasing also. With that done I was able to hook the tiller to the 3 points and then attach the driveshaft very easily.

Did you remove the shaft cover for the photo or does your pto saft not have a cover? I would seriously consider getting a shaft cover for your safety.

I couldnt tell what model tiller you have but I found that If I get my tiller up on blocks I can roll it back and forth to make 3pt connectons alot easier. I have always had problem getting the tiller connected in the spring. Usually figure a couple hours to make the connections. It seems to be more an art than science.

Brett,
I didnt have any problem connecting the two parts of the shaft together, just lined up the key way and slid right in.

"Did you remove the shaft cover for the photo or does your pto saft not have a cover? I would seriously consider getting a shaft cover for your safety"

I'm sure there are lots of good reasons for having a safety cover on that shaft, however if a person was really intent on commiting suicide by tractor, he could still probably manage to stick his hand under the cover, get it caught in the spinning yoke so that it wraps his arm around the shaft a few times until it rips it off at the shoulder and he bleeds to death, or he could simply do as I do and never get off the tractor with the pto spinning or let anyone else near it.

No, mine did not come with a shield, that is why I dont get off the tractor with the PTO engaged.

My "little key" is blob of steel over two splines and lining up that with the other, female, end is very difficult. bw

Norm you make a really good point. The shaft on these tillers are fairly short and harder to get to than say a a long bush hog drive shaft. Yes the PTO shields are a good idea but if you are getting that close to the rotating shaft you are also "danger close" to those exposed rotating tines of the tiller.

I was not concerned about a intentional act but an acidental one.

Sorry guys but I have to agree with Gary. It only takes one time getting off with the pto engaged to end in tragedy. /forums/images/graemlins/crazy.gif We've had some accidents in the neighborhood over the years by very experienced farmers who wish they had an arm or hand back. One fellow wishes he had both arms back. /forums/images/graemlins/shocked.gif You only have to stumble, get dizzy, look away, misjudge, for an instant and life changes forever. Can't be too careful!
Happy and Safe tractoring

my tiller shaft is barely 12" long if that.. I don't realy see a reason to run a cover although i usualy do.. more of keeping dirt out than saftey i think i've pretty much drilled the idea of killing the tractor if i get off.. although there could be a piece of debris that could be launched or get caught up or slung?

Also how does everyone run a slip clutch on these tillers? i wouldn't even have a shaft if i run one i figured the actual shaft would be about 1-2" when you figure the 2 u-joints and then the length of the slip clutch.. any pics?

I don't run a slip clutch on my tiller. I do run an over-running clutch on my bush hog. Had to re-size the pto shaft with the liquid hot wrench to the tune of about 5 inches. I have seen slip clutches on older farm equipment that didn't use u-joints, just fit in between a splice in the shaft. Common on older sickle bar mowers. I think my tiller shaft is about 18 inches, almost to short for a slip clutch too. Although a slip clutch would have to extend life of the tiller and tractor.
