low hydraulic pressure

[johnnyniceguy]

Having trouble with snow blower and or V-plow...I guess it would be all auxillary sytem related. I pull a code that tells me low hyd pressure. Seems like a valve stays open and I don't get a constant pressure of fluid to drive blower or move cylinders on v-plow. Stem valve was used by bobcat service but he would tell me no more. It seems to be on for a while--than off. The snow is falling. Any one had this problem????

I don't know anything about your machine but I do know about hydraulics.
Is it making noises you haven't heard before?

Don't know how long you've had your machine but have you drained water out of the hydie tank?
How cold is your operating area?
Does the problem ever go away?
Is the engine bogging down?

With what little information is available...it sounds like your have a relief valve dumping to tank that shouldn't be.

What was the last the last thing you tweaked on the machine?

I'd look all over the machine for stuff that is not obvious....like a rock collapsing the suction line...if it has one.
Re-read the manual...maybe it's something Homer Simpson would do?
A Frozen suction filter?

I pump concrete....so hydraulic problems are not unusual....start with a fresh set of eyes and check over the obvious and least expensive problems.

There was another thread about a bad batch of pumps spitting metal into the system.......uggggh.

I had this exact problem with my TC. A pressure/flow test revealed the issue. I have significantly better performance from my snowblower now.
