B2301 tipped over

[modeck]

My tractor went over a steep banking. After it was recovered the left brake is out of oil but the level shows full via dip stick. Also rear lift only works from 7 to 8. Any idea?

What do you mean by that statement? How would you know the LH brake is out of oil?

You lost me at left brake is out of oil??????

Look at all of the linkage for the three point, especially the feedback linkage.

That left brake is sure interesting, but I'm wondering how the rear lift (do you mean the 3 point hitch?) knows what time it is.

@modeck welcome to the forum.

I know nothing about those braking systems, but I want the “tipping story”.

It was a crisp autumn morning when I decided to tackle the overgrown field on my property with my trusty Kubota B2301 tractor. The air was filled with the scent of fallen leaves as I maneuvered the compact machine up the gentle slope, the engine humming steadily. But as I crested the hill, the ground gave way unexpectedly, sending the tractor tumbling over a steep banking into the ravine below. I managed to jump clear just in time, my heart pounding as I watched my prized possession roll to a stop amid the brush and mud, wheels spinning futilely in the air.

Hours later, with the help of a tow truck and a few neighbors, the Kubota was hauled back up the embankment and onto flat ground. Shaken but relieved, I inspected the damage. The exterior looked battered but intact, yet when I tested the brakes, the left one felt spongy and unresponsive. Puzzled, I checked the brake fluid reservoir—the dipstick showed it was full to the brim, but clearly, something was amiss, as if the oil had vanished into thin air without a trace.

As the sun dipped low, I fired up the engine again to assess the hydraulics. The rear lift arms responded sluggishly, only functioning properly between positions 7 and 8 on the control lever, refusing to budge beyond that range. Frustrated, I realized this mishap had turned a routine day into a mechanical mystery, and I'd need to dig deeper to get my tractor back in working order.

The next morning, I woke up with a knot in my stomach, determined to unravel the mystery of my battered Kubota. Coffee in hand, I headed to the barn and started with the brakes. Recalling some online forums I'd skimmed through late last night, I figured air might have gotten into the left brake line during the rollover—explaining the spongy feel despite the full dipstick reading on the transmission fluid reservoir, since that's what feeds the wet brakes. I grabbed my tools, jacked up the rear left wheel, and carefully bled the brake system, starting from the bleeder valve. Sure enough, a mix of air bubbles and fluid spurted out until it ran clear. After topping off the fluid just to be safe, I tested the pedal; it felt firm again, like nothing had happened.

Energized by that small victory, I turned my attention to the rear three-point hitch. The position control lever, marked from 0 to 10, was only responding between 7 and 8, which had me stumped at first. I inspected the external linkages as suggested in those same forum threads, and there it was—the feedback rod had a slight bend from the tumble, throwing off the hydraulic valve's sensing. With a bit of careful prying and a replacement rod I had from an old parts bin, I straightened and reinstalled it, making sure the connections were snug. A quick test showed the arms now lifting and lowering smoothly across the full range, no more stubborn glitches.

By midday, the tractor was purring like its old self, ready for the fields again. I took it for a cautious spin around the yard, brakes gripping evenly and the hitch performing flawlessly. That mishap taught me a hard lesson about checking slopes more carefully, but it also reminded me how resilient these machines are—and how a little DIY know-how can save a trip to the dealer. With harvest back on track, I parked it with a sigh of relief, grateful the only lasting damage was to my ego

That was wonderful! The AI must have been there as a witness, it wouldn't make all of this up!
