pto lever guide bracket

my tro did the "pop out thing" while mowing.....I removed the guide bracket and now its working but the tractor seems to bog down a bit when mowing and it seems to be harder to take off mowing in second gear....Seems overall to lack some power...Its a 1957 low boy cub...( I also have a 53 )....Any comments out there, this is my first post....I tried earlier but was unsuccessful .....Having a bit of a problem with the website....Dave

Welcome to the forum, the sliding PTO Hub is probably worn at the splines and it kicks out, not uncommon, here is a link showing the part, http://www.tmtractor.com/new/pt/449-1fp.htm, you can look through the filler plug for the transmission and see it move back and forth with the lever

Thanks for the reply Tim...I'll check it out thru the filler plug...Dave
