I felt the same, so I searched for this thread to see if anyone else had trouble with the lever. Now, I *prefer* to mount and dismount from the left, but sometimes there is an obstruction, and sometimes the thing I need to do is on the right. So why should my tractor dictate which side I board, especially for no good reason.
So, today I combined some of the best ideas here, for a great solution on my BX2670. I heated, bent, and cut the lever.
I removed the lever, heated it just above the factory bend, then I bent it inwards and upwards, or left and up from the driver's perspective. I got it out of the silly OEM location, and closer to the throttle lever, at about 2 oclock on the steering wheel, and close enough so that it hits its left (tip up) limit about 1" from the wheel. Then, I cut about 2.5" from it.
It's beautiful. With only 2.5" removed, I still have fine control and easy motion. I can still reach it very easily with the seat all the way back. If you can reach the whole steering wheel, you could probably reach my lever. And the path on and off from the right is clean and easy, as well. For the record, I am 6'1" 215lb.
I didn't get any "before" photos, but I'll post some "after" photos later.
