    Is there a block drain plug on the B7800?

    In changing the anti-freeze in my B7800 I can't seem to find a block drain plug and the owner's manual has no mention of it. Just the radiator drain that doesn't seem to do a thorough job. That seems odd. Anyone know if there is a block drain plug on the B7800?

    B7800 owners--Do you like your front end loader?

    My B7800 is really just a dedicated lawn mower but I do spray with it and use a couple of attachments around the house. It does not have an FEL because I have other tractors that do. Now I wonder if I should get an FEL for it. What has changed is that my wife needs more help gardening and...

    B7800 Kubota Replacement Seat

    The seat on my 2006 Kubota B7800 is falling apart. It was never very comfortable and was sloped way to far forward anyway. I would love a recommendation on a replacement seat that is comfortable, perhaps with arm rests and is easy to install. Any recommendations.......thanks in advance.

    Can I use SUDT2 in B7800 HST?

    I picked up some SUDT2 for a HST change in my B7800 since I thought UDT was good, SUDT better and SUDT2 best. Go with the best I figure. Also thought that SUDT was being phased out in favor of SUDT2. Can anyone confirm this so I can make sure I do the right thing? Is SUDT still being made and...

    B7800 mower deck wheels have replaceable bushings.

    I broke off a grease fitting on my B7800 six ft belly mower on wife's darned rocks (ouch) and in the replacement process discovered that Kubota uses bushing inserts in the wheels of the mower. What a pleasant surprise since a lot of makers do not.. One of my bad feelings about the mower was...
