The underside of my newer Kubota

I didn’t see any and decision to replace the line was based on the leakage.

Those lines have to remain in the exact same form as from the factory or they will leak.

If it was mine I would be tempted to tap the bores where the lines go in and replace them with a hose. I might even consider epoxying the fittings in the transmission side to avoid chips from tapping threads.

I was thinking maybe switching them to rubber but as long as it's under warranty I think I'll delay that until after the warranty is over. The o-ring fittings are good connections as longs as they go in straight, it's just that the iron pipe is so ridged there is no room to get them lined up without nicking one of the o rings. Hopefully the mechanic will have a solution.

I second the idea of a skid plate! Could be made of pref steel with small holes to allow air and any water or possible leaks to drip.

I'd leave it to the mechanic.
