Like old said, use 540 only. There should be a selector for 540 or 1000 rpm if it's the same shaft. 1000 rpm is usually only used on tractors approaching 100 hp for implements like large balers and such. 1000 rpms on a compact tractor would be used for things like a belly mower etc. A 540 shaft is 1 3/8 six spline and 1000 is 21 spline I believe. All compact implements that go on the 3 pt. should be 540 rpm unless they are a special attachment that runs at 1000 rpm. Your manual should specify engine rpm for 540 pto rpm. If you don't have the manual and the tach doesn't say, it is usually about 3/4 throttle or slightly more if heavy going. Dave
