If this is anything like log splitter setups here with horizontal engine where the new engine pto shaft is long it is a simple matter to just shorten the PTO . Just got it is done squarely. Here several jobs required shorten the shafts by 3/4 of an inch so the Love Joy coupler could fit inside the housing that coupled the hydraulic pump.
Now of course I have never seen a SB33 mower so others here that is more familiar with the setup might know better.
