3pt adjustment question

[agcomike]

I was wondering what the toplink adjustment was for? does it change the raise to lower angle? my tiller is straight on the ground but when i raise it up it angles back bad and hits my guage wheels..

Mike:

The Top Link

controls the front/back tilt of an implement. The tilt angle will change as an implement is raised or lowered because of the geometry of the 3point system.

On my tiller, the normal toplink is replaced with a flexible toplink that came with the tiller. This allows the tiller to sit level on the ground, stay level as it floats up and down over the terrain and stay level as it is raised for transport.

Can't picture what you mean by hitting your guage wheels when you raise your tiller. Which guage wheels?

Thinking about the geometry of a 3 point, with a normal top link, the implement will "tilt back" as it is raised (I think - I'm not near my tractor right now).

Does your tiller come with a flexible top link or does your top link look like the ones pictured above?

If you have multiple attachment points for the top link at the tractor end, use the lower one. This will alter the arc of rotation on the top link and even out the tilt of the tiller. Similarly, using a higher attachment point will level out the tilt on an implement which tilts toward the tractor too much.

mine's a std. toplink do you have pics of this flexable one..

The wheel's i'm talking about is for the jap. tillers which don't have the adjustable skirts on side. It has 2 pieces of pipe from the top link arm around the gearbox back to a screw jack and 2 large wheels that stand out 2 ft on the back of the tiller.

When i set my wheels to keep the tiller from digging in when my 3 pt raises it still is on the ground and when i reverse the wheels jam into the dirt and bend the wheels 3pt and everything else..


Thanks alot so the lowest toplink hole will lessen the arc that' s what i was kinda after but this flex toplink is interesting..


thanks agian..

I'll take some real photos tonight or scan it from my owner's manual. Attached is a crude attempt to draw it. There is a fixed piece that attaches to the tractor top link attaching point with pins through two of the three holes. Then there is a short link that goes between that part and the tiller. As the tiller moves, this short link "floats" - providing "slack" between the tractor and the tiller.

I'd love to see a picture of that tiller - I just can't 'see' it in my head.

I don't understand why the wheels don't pick up with the tiller, or what is the point of them? Should they remain on the ground carrying the weight of the tiller at all times, and you do not use an upper arm with this type of tiller (or a flex one as mentioned)?
