Oil & Fuel Changing Gear Oil on a RCK60B23BX Mower Deck

[easygo]

I think the deck on my tractor (B7510) is the same as the 60" on the BX with modified hanging pieces to make it fit on the tractor. Your description should walk me through the process pretty well. Thank you

Do I just fill the gearbox to a marked level, or bottom of the filling hole?

bottom of the filling hole.

If your deck is similar to the RCK60B23BX, the fill hole is on top of the gear box. The drain/sight plugs are on the side. You fill to the bottom of the sight plug (top plug). For me, it took about 12oz (the manual said .38 qt).

I finally changed my gear oil this weekend after getting all of the great advice from this forum. I went ahead and attempted the quart plastic bag trick and didn't do so well. I blocked the opposite end of my mower up but I guess I didn't get it high enough. At first, all fluid went into the bag but as it slowed down, the fluid ran down the side of the gear box and not all in the bag. Oh well, not too much of a mess. I finished draining the fluid by getting out my manual pump extractor. I think I will buy a better extractor for the next time and just use it.

extractor is the way i plan to go.
Less messy.

Indeed. As much as I love my Kubota, I must admit that the first time I realized this, I just about fell off my feet. I just couldn't believe that such a reputable company could sell tractors with such idiotic, user-unfriendly and potentially damaging designs.

On my deck (RCK60-F30) even filling the gear box is an incredibly dicey proposition. You have a super cramped space with less than one inch clearance, an access angle for a spout or a filler that's over 75 degrees, and both acess holes are JUST ABOVE THE BELT... Let just a couple drops of gear oil fall down there, and... well...

Hello, newbie here. Maybe related to this thread, or perhaps should have read thread before hand. Anyway. Seems my gearbox is stripped out or something. When i engagge the mower it just grinds and blades don't turn. Question is the gear box something i can replace myself, or do i want to. Not real mechanical. If so how do you get the darn thing off?

Ditto. Put a block under front corner away from drain and bent small disposable aluminum pan to catch the oil. Pan rested on belts. Left it there for about 15 minutes while box drained. Not a drop on mower deck!

I am draining my MMM 54 gear box oil for the first time since 50 hours. I followed the advice of those who've posted on this thread. I put a block under the opposite drain and the oil is barely trickling out. My garage is about 65 - 70F and the gear oil has not been used since Nov 2009. Does this sound right? Probably a tablespoon of oil has drained in about 30 minutes.

No it doesn't sound right. On my 60" deck the oil flowed pretty after removing the top plug and the drain plug.

no it doesnt sound right either. looks like you were low the whole time.

I think you're right. Also, I didn't have the top plug open. It took about 10 hours to drain the dumb way. But I will say that the containers used by Chinese restaurants around here are the perfect size for neatly draining the gear oil into.

Removing the top plug will make a big difference. It allows air to flow in thus breaking the suction effect that happens with only the bottom hole unplugged.
