It depends on how deep your pocket is primarily;
For the front mounts you need the underframe and or the quick hitch mount for the mid P.T.O.
The loader mounted front mounts and the front mounts that are hydraulic drive will enter into the very low 5 figure cost for you.
The Mid P.T.O. drive front mounts are less costly BUT you will need a lot more as far as, the underframe, and reversing chain drive or gearbox and you would not be able to use the loader if you have the quick hitch parts mounted on the front for most models.
AND you will lose ground clearance in the process because of the underframe
which is non issue with a rear mounted snow blower.
A rear mount "Pronovost PUMA group 1 snow blower" which is the best snowblower in "my opinion" is less money and more bang for the buck as it has no sheet metal in the units construction.
A rear mount snowblower and an open station hydro drive tractor fit well together as all you need is a suicide knob for the steering wheel and a pillow for the seat reduce stress on your lower back while you twist in the seat slightly usiing your left foot to depress the reverse portion of the directional pedal to watch over your shoulder OR use a big truck mirror to watch while you use the blower while looking forward-this is why the steering knobs are so nice as the tractor will go where you steer it much more easily and there will be less stress on your forarms and hands.
You have to keep in mind the following:
1. fresh snow fall and packed snow from freeze thaw cycles wieghs 21 pounds per cubic foot or more.
2. the open auger design of the two stage snow blowers floods the impeller drum all the time it is operating as the delivery volume is not constant as
THE AUGER IS OPEN and does not have a ribbon suirrounding a tube like a grain auger or "single stage snow blower auger"
using the 21 pound per cubic foot example:
if you are traveling at 2 miles per hour you are advancing at 176 feet per minute AND if you have a 4 foot blower:
176 feet by 4 feet by 21 pounds per cubic foot you will be dealing with-
7.4 tons of snow per 176 feet of distance with the four foot width with a 1 foot snow load.
The slower you travel the faster the snow is "cast" aside not "blown" and
you will not flood the impeller drum and plug from the heat of friction created by the rotation of the impeller.
I would contact Ken Sweet who is a proud sponsor of the forum in good standing and ask about his line of rear mounted snowblowers.
You can find suicide knobs/steering knobs at the local TSC.com or agsupplyonline.com and other places
The only real option you have if you want a front mount blower for this tractor is a Bercomac motorised snowblower for an ATV or RTV
and a front hitch mount winch kit from Bercomac for it.
WE have a lot of Kubota Owners with rear mounted blowers here on the forum, and they are very happy with them.
Candidly the first thing you should do is make a decision tree and go from there.
