I just purchase the rear remote kit for my L3901HST. My dealer gave me a few boxes of my order with a ton of parts that look like and state that they fit the L4400, 4600,4701 but nothing on the L3901. The piped manifold included in the kit looks like it will mate up to the transmission as it is the same shape but the instructions are terrible. Maybe when the last box comes in it will have correct lever plate and the info I need with better instructions. Does anyone have any info on this kit working on the 3901?
