B7200 3 point hydraulics

[Yemmers81]

Hi All

Looking for help please. When I use the topper on my B7200D even when the engine is running the 3 point arms slowly drop down. Any suggestion as to the cause please?
Dealer has suggested rear pump has failed which could be quite costly, but looking for advice before taking it in.
Thanks in advance

If the pump lifts the Topper, then it is OK.

Cheapest thing to try first would be the seals on the piston which lifts the 3 pt hitch.

See parts illustration. These parts cost around $30 US and are easy to change.

I cannot find any manuals for a non HSD B7200 so cannot tell exactly what hydraulic control exists on the 3 pt.

Thanks for the reply.
Will start there for sure

Not sure if anyone has any other illustrations on the 3 point hydraulics, as that would be very useful

I suggest you go to Kubotabooks.com and download the B7100 WSM.

I suggest this model because the illustrations are among the better ones and it is the previous model to your tractor.

Have you tried opening up the rate of drop valve under the seat between your legs? Maybe someone closed it or it has a piece of debris in it.
