Once you have righted the tractor allow an hour for the fluids to drain back to their proper location.
Check fluid levels and look for leaks and other obvious damage.
It's possible that fluid may have leaked on top of the pistons. Attemping to start the engine in this "hydrolocked" position can cause expensive damage, for example by bending a rod. Instead, remove the glow plugs (instructions here) and turn the engine over a few times to eject the excess fluid.
Check the ROPS for damage. If damaged, replace it otherwise it may not protect you if you roll the tractor again.
Wheel Spacers
At least one owner has purchased wheel spacers for a BX24 from Bro-Tek, widening the rear wheelbase by 4 1/2 inches. This will increase stability, but there are some issues to watch out for:If you use a 54" mower, the wider wheel spacing will interfere with the rear guide wheels of the deck. In short it seems that you can't have both the spacers and mower installed at the same time.There is a question as to whether the spacers will increase the stress on the axle. The BX24 manual warns against increasing the distance between the wheels but does explain the risks. Consequently the warranty will probably be voided if damages occurs in the axle area after spacers are fitted, The spacers are not currently viewable on the Bro-TekSeeweb site, but here are some pictures, to find out more contact RichardWheelatSpacersBro-Tek.page.
Reverse Pedal Position
Some BX models have the forward and reverse pedals widely spaced. If you find this inconvenient, you can try lifting the forward pedal instead of depressing the reverse pedal.
Sudden Stop in Reverse
(Applies to BX24 and others.) When in reverse, the tractor stops with a sudden jolt when you lift your foot off the pedal. This is normal, though undesirable. Various owners have complained about it on the TBN forums. Currently there is no cure offered by Kubota.
One suggested improvement (BX2350 and maybe others) is to locate the large spring under the right-hand side of the tractor, with an adjustment on it. If you back off on the adjustment, it should put less pressure on the linkage to return to neutral.
Accidental Operation of the Shift Lever
If you are concerned that you might unintenally change gear into neutral while grabbing for one of the other controls, you might try making your own"shift lock". Two home-made fabrications (one in metal, one in wood) are described in the TBN discussion below. [TBN] Shift Lock for BX24.
