Read articles →This is part two of a two-part DIY service, picking up where the engine video left off to focus on hydraulics and transmission. It's a detailed hands-on walkthrough: draining and refilling hydraulic fluid, replacing the inline hydraulic filter and main suction filter, servicing the front axle/diff, checking dipstick levels, and even sharpening flail blades. Owners doing their own 3320 maintenance will get the most from it, especially alongside the companion engine-service video.

It is the yellow cap on the top of the rear axle. Check you can remove it before draining the fluid out.
No, the new inline hydraulic filter did not come with O-rings, so the old ones were reused on refitting.
Fill with oil, drive in a figure eight to distribute it, let it settle, then dip the stick without screwing it in.
Use an angle grinder to put a 45 degree beveled edge on each flail evenly to keep the shaft balanced, avoiding a razor sharp edge.
