Get some greaseable pins.
I'm not fond of greaseable pins on any implement or on Kubota OEM buckets or attachments for a couple reasons. mainly because they tend to get filled with crud that you have to clean and remove before greasing because if you don't the crud gets injected with the grease and two, the machined space is somewhat limited so many grease gun tips won't fit on the fitting head properly. In fact I modified all of mine on both my loaders with tapped in grease fittings, no exceptions and I don't use the recessed fittings at all and on a minor note, the drilled in grease passage as well as the cross drilled grease passage, somewhat weaken the pins as well. IMO, it's a poor design on any tractor or excavation equipment. Pivot pins are always a high stress part and usually heat treated but lax maintenance will eventually destroy them and lack of lubrication when the implement is under heavy load causes the starting torque (implement cylinder end and tractor end) to be excessive anyway. My stuff (everything) get greased ever 10 meter hours or when I put them away. Like the old well worn saying goes.. "It never breaks sitting in the barn" so I'm pro active about maintenance BEFORE putting anything away and that includes my prime movers. In fact, I'm in the middle of servicing them right now. Lube oil, transmission fluid, all filters including the air filters and all OEM Kubota parts (in my case). Check the air pressures, top off the starting batteries with distilled water and check all the connections for corrosion as well.
Prior to putting them away for the winter, I'll make sure the starting batteries are fully charged and the I break them out using the master disconnect. Flooded cell batteries, when fully charged won't freeze until the ambient temp is at -40 degrees (F), and a fully charged flooded cell battery only looses about 5% of it's charge when sitting and not in any circuit. I get excellent service life out of my starting batteries too. Usually 5 years before I see a marked drop in static charge or amperage delivery and then they get changed out and not some box store battery either. Only fresh Interstate's purchased from a volume dealer like my local heavy truck dealership, where I know the starting batteries have a rapid turnover.
Any flooded cell battery sitting on a sellers shelf is getting older even if not installed. A flooded cell battery begins it's useful life once the electrolyte is installed, no exceptions to that unless it's a 'dry charged' battery where the electrolyte is provided in a separate package.
Not many come that way today, just RV batteries for motorbikes, that I know of.
