I have a T300 bobcat when I hook up my brush cutter it works ok for about 2 minuets then the general warning light comes on and the brush cutter stops working all other operations work ok boom up and down and tilt, I shut it off for an hour and it works aging for 2 more minutes. anybody have any ideas what's going on?

OK first off, are you sure your machine is compatible with the implements hydraulic flow requirements!
many people buy/rent implements, that need more GPM than there machine puts out, which will cause the implement to either just not work, or not keep up, and when its struggling to keep up, it can cause a machine to shit down, to prevent damage to its pumps or hydraulic system!

SO< you need to know what your machine GPM is and what the implement needs

example if your machine puts out 30 GPM and implement requires 45 GPM< its not going to work, or will work a little then shut machine down, with an error
and if you keep going you risk damaging your hydraulic system!

this is why they have GPM ratings on things, so you can match them up , so you know they work with your machine, every machine is different! as are implements!

and brush cutters can be very HIGH demanding GPM implements!

I bought this bush cutter from a dealer for my machine, and I have used it a lot with no trouble. this is a new problem

 

[baby jenks]

the machine don't shut down just the aux hyd.

 

[mrbb]

is the hydraulic oil level low?
is the fluid fresh?(filter fresh too?)

 

[baby jenks]

fluid is full, new filter in 2022
all the machine hydraulics work ok but when the general warning light comes on the aux hydraulics stops working

I know we used to set units up however we would use a flow meter and psi gauge inline to make sure that they were a match, if you have a high flow unit and it is running over relief it will generate extra heat in the hydaulics, or if the relief valve has gone bad it to will creat extra heat, noramlly a unit that is not a high flow unit will give very poor performance ie cutter will slow down, we had a different time had to add a flow devider to get the flow right, a flow devider is designed to leak off the excess flow with out creating a lot of extra heat.

also how many hours are on this machine, as things do wear out, as if your saying it worked fine for you and suddenly now having issues, maybe a pump or seal/or leak some place is starting to cause issue!

 

[baby jenks]

the main hydraulic pump was replaced last year not sure on the hours I will look tomorrow.
this machine is not used a lot Maby twice a week

I replaced the two solenoid stem valves that seems to have fixed it.

Do you have the "deluxe" panel with the display on the Rh side? Or are you able to read the LH panel display? If you hold the light button for 3 seconds, when the concern accrues, what numbers pop up? Like 09-09 or 59-09
