T190 and SB200

I have a question about this. I have a T190 high flow and a SB 200 attached to it. The problem I have is that when I use it during winter time blowing snow it seems to lack the power to throw out the snow. If I test it now during summer time in the lake it throws huge amount of water quite a long distance away from the chute.

Is it possible that there is something that has to be adjusted on the snow blower or is there something else that causes this problem?
 
well a few things come to mind , one is, are you sure your t190 has enough flow ate to run your blower at full capacity?
a lot of blowers take a lot of GPM"s of flow to work properly!
and many older machines don't have the GPM's to run them
add in heavy wet snow, and cold temps, and things could not run so well!
a lot of salesmen, don't care about the right set up[ and will sell you anything to turn a profit, so, maybe you were sold a blower too large or uses too many GPM;'s than your 190 puts out!
its actually not that un common to hear this happen!


next is hydraulic fluid, in very cold temps, it will flow or should I say could flow at a lower rate than in summer time hot warm air!
I know some folks switch to a thinner oil/fluid when working in very cold temps, to get them to flow better!
so changing to a thinner fluid may help?

lastly, I would think all blowers have bearings and or grease fittings, and if some get worn or say sort of seized up, they can add resistance to things, making it harder to run them , making blowing snow harder

and last last, you cannot really compare water to snow, snow builds up and can be heavier, and even turn to ice, slush and compact causing resistance water doesn't, so its not a matching game to compare them to each other!
I would start by looking at spec's of your blower to what your 190 does in flow rates and what are needed!
and then, are you running skid steer at 100% throttle to get the most GPM's when running things

if your machine is barely meeting the requirements of the blower, you found the weak link

and don't forget MFG"S fib a little to make sales on what they make in flow rate hp and ?????

and running something at MAX rate to keep up, over time, all things wear out and don't make the MAX like they used too!, pl;us its IMO< adding wear and tear
and IMO,(im no expert) you kind of want an implement to not need MAX of what your machine makes for it to run efficiently or properly, there should be some wiggle room and extra GPM"S left on the machine side for an implement to run properly!
 
Moved this over to the General Bobcat Skidsteer Forum where the T190 crowd will actually see it. That breakdown of flow rate versus what the blower needs is a good angle and the water versus snow point makes sense too since one just runs off and the other packs up. Hope Hatti gets it sorted.
 
Thank you for your reply.

The gpm should not be an issue. The blower requires a minimum of 14,5 gpm and the T190 gives 25,5 so I will check the oil and maybe change it to a thinner one.
 
ok a few things I found you may have interest in

in this post on this site there is a user with like issues, and he says the SB200 72 inch spec's are 21-26 GPM ona 72 inch model, and found a sb200, 66" is 14.5,
so are you sure you have the right spec;s on your blower?(then again the spec's in these spots could be wrong, but ??)

you may benefit from reading th is threads

and then I also found this, that may interest you



Technician:
asked about low power and blowing snow only short distances! (so might benefit you if you have your machine flow rate actually checked to see what it is making,as all things age and well, don't have the same power they used too)BUT the guy replied with the fix he found)

"I have been a mechanic specializing in Bobcat equipment for over 16 years."

There seems to be an issue with the snowblower or the loader. This blower should project snow at least 15 to 20 feet when connected to your loader. It might be that your loader isn't providing enough flow to the blower. I recommend taking it to your Bobcat dealer to have them test the flow from your loader. If that checks out, then there may be a failure within the blower itself. I hope this information is helpful.

Thank you, nothing is wrong with the snow blower or the machine; however, the skid steer is old and tired. It barely meets the minimum required GPM, and when considering the skid steer's age along with heavy wet snow, the impeller bogs down. This leads me to my question about varying the flow from the auger to the impeller. I received a diagram for the snow blower valve body, and the orifices can be adjusted for this modification. However, they could not provide a schematic on the flow, so I installed a high pressure/high volume valve on the auger hydraulic loop (next to the valve body). By restricting the already limited flow to the auger, the impeller sped up. Now, even with wet snow, the impeller is throwing the snow over 20 ft.
 
found this this info too may interest you

"When I ordered my SB200 in 2008 there were two motor options for the fan. A high speed, lower torque O/P motor that would throw snow further if it were light and fluffy and a lower speed, high torque O/P fan motor that pushed wet, heavy snow easier but wouldn't throw it as far"
