Hi y’all,just found this forum about a week ago and amazed at the wealth of knowledge on here, I’m not really new to tractors,grew up on my grandparents 600 acre farm back in the late 80s-early 90s,finally able to move our new family out of the city about a year and half ago,will tell y’all about the best penny I ever spent later,don’t want to lose friends so soon lol,but to my question or two,have l3200,question with diff lock,is it supposed to stay engaged after pressing on foot lever or do I need to keep my foot down on it to stay engaged,have no manual for tractor,second question,broke a tooth on LP box blade,can I replace just the tooth or have to get the whole scarifer?
