I would think that you will be ok with that loader, We ran a 12' loader model on a Case 580 when we had to and it did ok, I am sure that it was not supposed to be on the machine, but it did the job. I would think that the machine would have more than enough power. Even in really big storms that the machine might be under powered you would just have to take smaller bites of snow Just my two cents.
What does the 544 weigh?
I run a homemade 11' pusher on a Cat 16000 pound loader,
It is 4' tall with 40" long wings power is not a problem but traction is not the best I run tire chains most of the time with more than 6" snow.I am pushing 600 to 800 foot runs
I think 16' would be a little big for the 544 in the heavy snows,a smaller blade would allow much faster cycle times and be easier to handle.
The new Deeres are really quick a few extra rounds might be OK in the light snows.
If you get the big blade let us know how it works out.
we run a 16' on a case w14 only problem is that we have to replace center pins every 2 years we found if we haul the loader from lot to lot its not nearly as hard on it asgoing down the street with 2000lbs plus out the front
The 544 weighs more than I thought at 25000# it seems each new model gains a little weight.
There are no pushers in my area so I dont know volume of factory made units,The 11ft one I made looks taller than the photos of others I have seen so it may carry more snow than a 11ft factory one.
My little 16000# Cat works well but if I made another it would be 10ft for this rig it would be better in crowded areas and better driving on the road.
When pushing heavy snow taking only half a cut I can really feel the side draft I expect it would be more with a wider blade.
It would be great to have a big one and a small one to fit the varying snow conditions.
I have only used mine for only two years so I am not an expert.
My cat can usually handle up to 6" snow no problem and make the full 800ft run,When its really wet there gets to be a pile 15ft wide and probably 10ft thick.
I found it works best to make a couple trails through the lot then take a new cut full width till the blade is full then run down the cleared trail,Then keep widening out the start of the cut sort of funneling into the cleared trail.
I need to stack the snow so I also have to push the whole load up the pile,It really gets light on the back wheels but its kinda fun.
Some of the less experienced operators had trouble with traction because they let the blade float,I set down so about half the blade weight is carried on the loader works well I run chains on the front wheels.
This year I will put about 800# more rear counterweight to balance it out better.
