    B7510 - Trying to understand Fuel Solenoid

    First of all, there is nothing wrong with my tractor. My concern is having something fail, having the solenoid drop out while using the tractor and not being able to get it back to the house. After about an hour at my local "you pull it" junk yard, I found what looks like an exact match for...

    BX22 rear differential lock not engaging

    Not sure if yours is made like my b7510 or not. When mine was spongy, the linkage was deflecting and the lever just before it enters the transmission was not moving. I bought my tractor with it stuck and suspect it had never been used. To free it up, I stared by unhooking the linkage, put vice...

    1979 B7100 Fuel Injection Pump Rebuild

    Nice write up Barckyardwrench! I'm new to diesels, you can help me understand something. What is the best way to know which cylinder is firing? On gasoline engines, my mentor Bud Echols would pull plug wires off one at a time. Never saw him flinch. Thank You, Trent

    B7510 Diff Lock Story

    I have only a few hours under my belt with the tractor, but would like to share my experience with it. Before finalizing my purchase on the 7510, I had read about some occasional sticking of the diff lock. I went to the dealer and asked to check the machine over and drive it again. The tractor...

    Left-Right brake pedal question

    Imagine one rear wheel coming to a complete stop while the other rear wheel continues to travel forward. In the right conditions it can be almost like a zero turn mower. May be a bit hard on grass though.

    My new Quick, Easy, Rear Weight for the B7510

    Hopefully, My photo uploaded OK. Yesterday I mixed up a few bags of concrete and poured them into a 24" long round tube. The concrete cylinder is used horizontal and has a 1" PVC pipe though it. A rod will be used to hange the concrete by the 3PH arms. $20 invested and it increases tractor...

    Left-Right brake pedal question

    Traditionally, there has been a need for tractors to turn really sharp. I assume the intent is still the same today. With my old Allis Chalmers I could turn sharp, then with the help of applying one brake, really turn around fast - almost pivoting on the one rear wheel. Hope this makes since...

    zd28 running rough

    My B7510 did this when I mowed. It happened right after raising my butt off the seat for a couple seconds. Almost to the stalling point and slowly came back. Does it have an Injection pump solenoid? Is so, it may be loosing power or bad/dirty ground connection?

    jump start gone bad

    I don't know much about Kubotas, but I do understand how alternators and charging systems work. There should be no reason why you couldn't unhook the alternator, isolate the connections (tape up everything), and try again. In this condition everything should work except the charging function...

    New to me B7510 - Trick to removing side panels?

    Just bought the tractor with 440 hours, and starting to go over everything really close. I have tried 3 or 4 times to remove the engine side covers. Do the top latches just finally release after yanking on it enough? I have pried with a screw driver, and looked for a way for the wire keeper to...

    New to me - b7510 - neglected?

    Hello, I am the proud new owner of a B7510 with 440 hours. I have looked the tractor over and it appears to not have been abused, Everything appears to work OK and I like it. The only issue I see is it looks like both hydraulic spin on filters are original. They are both gray and have a dried...
