You need to pull the leg out of the frame to change a tread adjust cylinder on those sprayers.

Keep wheel on hub, slide whole axle assembly out with a tire dolly, fix or replace cylinder, and slide back together.

Also look over tread adjust shims well, if axle is adjusted often they are probably worn out.
