Filter is on the left side of the trans. When sitting on the tractor drop your left arm straight down and it will be in that area. Two bolts hold on a oblong plate. The filter is underneath this cover. There is a rubber,"o" ring That goes with this cover. Lots of trans/hyd fuild so drain this first. The screen/filter sets in horizontal to this cover. Will most likely be full of crud. New is under 20.00 I believe. Mine did not have enough fluid to flow every place with the restricted flow.
