Lienbach was the first implement brand I bought, a disk and potato plow. I was very naive at the time. I brought them home and hooked up the disk right away, It worked great but later found out they dont grease the bearings before shipping. Later on, I found another flaw - round gang axles where real disks will use square axles because the bearings, bushings, and the plates themselves will rotate in unison. you have to keep the nut on the round axles very tight in order to get that result and one gang I could not do that because the washer thats welded on to the opposite end from the threads broke off for no reason was rewelded non concentricly by a friend (not blaming him). The angle iron frame is not heavy enough so extra weight is needed, no big deal but after the weight is added stress was put on the inadeqautley sized top link attaching material and I had to reinforce it. After a year I replaced it with a rototiller.
Also due to my inexperience I thought the "potato plow could turn over sod - - not!! it just got bent up. I unbolted the 1/4inch stamped blade and put on a twisted chisel sweep and use it for loosening soil before I hand dig a trench it works well for that. All things said, IMO lienbach is an economy line for occasional light use only and a person would be better off buying used quality stuff IF possible.
BTW these were bought in 1993
