I'm pretty sure my 2009 Stahl/Leimbach track hoe is 4/2mm hose & fittings with a 350ml/min pump.
I don't have much desire to upgrade at this time b/c the speed which it operates is about perfect for feeding the jaw crusher, I'm waiting to dump bucket b/c receiver hopper is full.
But thanx for sharing your news of upgrade, I didn't know Leimbach had made any changes to improve hydraulic flow capacities.
