ditto that.
since you onle need the pto running to use pto devices ( unlike the old N series that needed the pto for hyds, ) you can leve it off when un needed.
fir thost that simply must have a pto cover then you have 2 good options. 1, buy an orc that uses a quick release collar instead of a pin on type... or, remove the 4 bolts holding the pto bearing carrier in and put in long studs.. then add nuts to hold the carrier on.. leaving some stud exposed. not get some pipe, add a cap to it, weld on 4 tabs using angle iron, so they slip over the studs.. then add nuts...
