3pt toplink lengths
Can anyone provide me the minimum and max lengths of the toplink. I will have to try to make one from regular toplink parts, Thanks, Stan
Re: 3pt toplink lengths
what works best for me. The toplink adjusted with about half the threads on both ends showing should extend out the length of the lift arms. On most implements the lift pins are directly below the pin for top link. With the toplink at this length you have adjustment in or out depending on the desired tilt of implement . Kubota is the only tractor manufacturer that I have found that does not set there tractors up this way. Their toplinks are about 8" short for some reason.

Re: 3pt toplink lengths
Hi,
There are no standard lengths for the pull arms or the top link. That all depends on individual machine mounting points. You need to set the top link length such that it hits a point in space in a plane with the pull arms when they are parallel to the ground.
The pull arms need to be long enough from their mounting points such that the Implement Triangle is clear of the rearmost part of the machine (usually tires or tracks).
The generic tractor stores carry a wide selection of toplinks to account for most differences in machines as well as the five categories of 3 points.
Also, if we are talking crawlers, they are Category II. Wheel tractors of the same model (420, 1010) are Cat I. So, don't get the wrong bits. You actually need an extra-heavy Cat II on a crawler. They have downpressure whereas a tractor doesn't. A crawler will twist a standard Cat-II toplink into a pretzel in a minute or two.

Re: 3pt toplink lengths
I have an extra top link if you would like the correct center link,
