Or cut out a notch on the swim platform
... Is there a way to limit the trailering upper limit?
That would only work to limit down stroke...... The. correct fix as mentioned earlier is to put spacers inside the cylinders.... Really not that bad of a job.You could put an external stop on the ram. Use some kind of very thick like an inch thick plastic like nylon and using a hole saw drill the inner hole to match the outside diameter of the ram. Then using a larger hole saw cut the outside as big as you need. ( actually do the outer diameter first) Then cut in half put over the ram and clamp with a hose clamp or better put a couple of SS screws in it. Back in my youth we had a tractor with stops on the rams so we could adjust the depth of our cultivator and make it return to the same depth after we raised it to make a corner at the end of the rows.

I'd go the spacer route instead of cutting the drive. . . Resale value to think about.
Simply shorten your trailering clips by 1 inch. Raise the drive until it almost touches the swim platform, install the clips, and lower the drive until the weight is on the clips. You DO use trailering clips, right?
