Flushing and bleeding hydraulic systems before the peak season the best methods

[Overtrail]

Before the busy season kicks in, I made sure to give my Kubota’s hydraulics a thorough flush and bleed.
It really saved me from a lot of headaches down the line.
Let’s share our tried-and-true tricks, clever hacks, and effective methods to ensure the system is bubble-free, smooth, and ready to tackle the season ahead.

It's a smart idea to do this before you actually need the machine. I learned the hard way when air got into my system right in the middle of a job. Now, I always cycle each cylinder fully extended and retracted about five times without any load. It really helps get most of the air out without putting too much stress on the seals.

I loosen the bleed screws on top of each cylinder and take my time working them until clean fluid starts flowing out. It can be a bit of a slow process, but it definitely pays off. I did this with my L4701 last spring, and I haven't experienced a single jerky motion since

Here’s my go-to method: after flushing, I run the machine at half throttle and cycle through every function fully about twenty times. It might sound like overkill, but trust me, the air bubbles eventually find their way out. It’s way better than struggling through hay season with spongy hydraulics!
