ABSTRACT:
A screen member for the hydraulic system of an agricultural tractor is disclosed wherein the screen member is formed with a threaded opening to permit mounting thereof on a stationary stud fixed to the interior wall of the hydraulic system reservoir. The screen member is sealed against the stationary stud by a sealing washer and against the opposing reservoir wall by an O-ring surrounding an access opening through which filtered hydraulic fluid is drawn from the interior of the screen member. The screen member is also formed with a handle projectable through the access opening in the reservoir to facilitate the rotation of the screen member for mounting on the stationary stud. The handle can be formed with an optional square opening for engagement with a standard rachet head to effect rotation of the screen member.
