T190 high flow not working

CjT · Jul 28, 2012

so my uncle has a T190 and he bought a bushhog attachment for it but the high flow doesnt work. you can hit the button on the dash but the bushhog will still bog down very easy. weve checked fuses and everything. any idea on whats going on?

Are you sure the machine has the high flow option installed. All the machines have the button whether the option is installed or not.

how do we tell if it has the high flow option or not? do we need to pull the pump or is there an easy way to look at it and tell? if you had a picture of the hydraulics bay of one that has high flow and one that doesn with any differences circled that would be really nice

There is another thread, I think just under the skidsteer section, I think, about a guy who added high flow to his machine. I think High Flow is essentially another pump which is engaged. The other thread had a lot of good pictures. You should be able to get an idea of what you are looking for from those pictures.

The easy way to tell is to look at the hydraulic pump. The high flow pump is longer and has more sections.
This is the standard pump.

This is the high flow pump.

The skidsteer will be marked as a highflow. If an older G series, it will say highflow under the T190 decal. On K series, there is a small warning sticker by the couplers. My guess if the light does not turn on at all and does not set a code, it is not highflow. There is a possiblity that the controller was replaced and the tech forgot to turn highflow "on" when programming. This is one of the options that has to be selcted when programming the controller. T190 with highflow are pretty far and few between so I would not be surpise if it does not have it. As others have said, they all have the button even if they don't have highflow. Same with two speed, all have the botton even though track machines are not available with two speed.

Many times used machines are repainted and new decals applied. What decals are present or not present may not reflect what options are installed. I've seen a machine that said high flow on the side and not have it. The person applying new decals may have seen the button and assumed it to be. So unless you bought the machine new and know that it has high flow the best way to tell is to look at the pump.

after counting the sections its a standerd flow pump. is there any way we can get a little more flow out of it? the bushhog works but you have to go real slow with it through brush an all. any selinoids or valves that can be adjusted? (dont worry we are not mechanically-clueless people trying to do this) it doesnt bog down, the blades just stop turning. thak yall for the help and pictures

There isn't anything more you can really do. The pump can only put so much out and turning up relief pressure will over time gernate the pump.

throwing it out there guys. in the bobcat world we refer to them as smart attachaments.what we mean is attachment has a controoler as well which comuncitates with base unit (in a nut shell it says here i am im hi flow please turn on. the reason for this is to prevent overflow to attach that cant handle it.. as i did not pay a whole lot of attention to what you previously posted . my bad its my time., first CONFIRM hi flow on base unit, secondly confirm required GPM of (busch hog) if yore trying to run OEM atacchaments its plug and play. if not well good luck things to consider are ? hey did i just introduce dirty oil or water into my 10 grand worth of hyd componetes;;;

I know this is an old post, but just noticed it digging through old threads. I had the same issue with my T-190. Besides the extended pump housing, the serial number is a good way to check the Hi Flow option. If your serial number starts with 5198xxxxxx, it should be the series with Hi Flow like in my 2003. My research showed that there were actually quite a few T-190's that came with the Hi Flow option, but was never activated from the factory or dealer. The problem was the amount of HP needed to run HiFlow attachments. If you used a Hi Torque/ Hi Flow post hole or tree auger you could run it, but you would be using upwards of 60% or more of available power. So if you ran a rototiller, brush hog mower or mulcher etc. you would have very little power left for mobility and lifting/lowering. My .02

One thing I want to add, hi flow only works one way. I had a high flow T250 with a poor performing cutter head. Quick test run I found I had to run the hydraulic backward to run it. Quick flip of the couplers, works perfect.
