I am looking for a workshop manual for my la854 loader. it is on my l5740 rops tractor. my loader is locking up in the down position sporadically. just before the float/unload position it is getting a hard catch to it then it locks up and my loader creeps down. if i push hard past that point it will free up and go down normally. l5740 service manual doesn't show any thing for my loader valve so I am guessing / assuming it is all in the loader manual. new valve is expensive, so I wanted to see if there was any other repair or rebuild options. my tractor has a direct linkage to my loader valve, no cable so i am thinking it is internal to my valve.
