Read articles →This is a machine-shop repair video, not a tractor overview: the creator tackles a worn-out Kubota L2550 suspension seat bracket, drilling and boring out wallowed-out pivot holes, fabricating custom pins, and pressing in a brass bushing on a mill/lathe setup. It's hands-on metalworking detail with real trial-and-error, not a buying guide. Best suited for owners facing the same seat-bracket wear issue who want a DIY machining fix rather than tractor specs or performance info.
Posted by the Dire Situation channel, an owner doing their own shop-level machining repairs on their tractor.
Bore out the wallowed-out pivot holes incrementally with drill bits and a mill, make custom pins, and press a brass bushing into the worst-worn bracket for a slip friction fit.
The bracket goes with another bracket that is not worn out, so making the pin bigger would force drilling out the good bracket too, which the creator wanted to avoid.
Slip friction fit all through, so tight you cannot turn it by hand but can tap it in lightly, with no more play in the joint.
He decided not to make new brackets since replacements were cheap on Amazon, about twelve bucks with Prime, so a new seat was ordered instead.
