I quite like the extra height for visibility and leg room. I'm not tall but the extra space makes the operator station more comfortable. Easier to get into and out too I think because moving between seated and standing is easier. I have sat in standard height seats and prefer the raised seat. Since it's all bolted, it can be adjusted or even removed depending on operator need (I don't have the winch installed yet as it needs checking over and I don't have the brace that connects to the top of the transmission - if anyone has a spare or the drawings, please let me know - or if someone wants to make me one for $)

I think you'll be fine adjusting or lengthening the linkage rod - you need to do is set the PTO in the "forward" position so that the control lever would be at a low angle that still permits easy grasping, and set the rod linkage there, then confirm you can fully engage the lever without hitting the seat and so that you can also easily grasp it to disengage
