[QUOTE="Mur Huwcun, post: 7071417, member: 33114"] Not aimed at you personally just trying to explain linkage geometry. A different length as said will not keep the mower level in work but different distances between top link and lower link affects the geometry. Consider a bale spike, the spike needs to be level two feet off the ground to go into the bale but as it’s lifted it needs to angle towards the tractor to keep the tip of spike higher than the base. To achieve this the distance between top link hole and lower link holes on spike needs to be longer than the same two mounting points on the tractor. For a machine such as a topper with a centre mounted gearbox with a PTO shaft you need the topper to lift just off level to stop the topper frame fouling the pto shaft and limiting the heigh you can lift it so again distance on machine greater than on tractor. If you wanted to lift an implement dead level then both measurements need to be as close as possible. Another example would be a fertilizer spinner that needs to be level ar work. Now the drawback is that the closer the two dimensions are on the tractor the more strain it puts on the tractor and therefore it’s lift capacity is reduced as not only is it trying to lift the implement its trying to hoist the rear if machine up in the air quicker. For example you would never have a plough on the bottom top link hole of tractor. [/QUOTE]
