First Question: Does tractor have enclosed cab. Been using a rear blower for 27 years, and unless the wind is calm, I ended up WEARING a large portion of the blown snow. This year, using different tractor, NEW CAB, FEL mounted SNOW Pusher and rear back blade, skid shoes are a necessity. Is the path/driveway paved? Not likely, then gravel/stones do not blend well with impeller fan on blower. I use hydraulic top link to adjust cutting edge attitude on blower, works quite well . Do you have rear remote hydraulic outlet, 1 or 2?
The best combo, my opinion, is CAB, Rear Blower, Front FEL Pusher. The bucket is too slow, some have modified the cutting edge with encapsulated pipe, ( no experience with that) but gouging is an issue. Fill, reverse, dump, bucket refused to empty, fill again, repeat, frustration, takes an eternity, and so on.
My R4 rear tires are very wide (17.5) and not loaded. Very disappointed in the R4. Have turfs on the ford, loaded, they performed much better, But the ford either pushed a 66 inch FEL bucket or snow blower and the current snow pusher is 84 inch. But Kubota is much heavier than the ford. As for snow blowers, Wood Max is more reasonable in price and very good reviews on this site.
The 84 inch blower is about $2500. I am considering for next year. Shipping is included, but they are made in my back yard, so a personal factory visit suggests a price break. The snow pusher is just so fast, nothing to empty, just lift and go again.
Plow requires hydraulic power to angle. Did that one year but used manual angle adjustment, pain in butt, abandoned that approach.
ThinK about loaded tires if applicable. Rear weight is the major performance variable, I am resisting adding chains. I mow lawn areas, loaded tires in the spring cause damage. Had an IH 2400B TLB, once, 2 wheel drive, very heavy, pushed unbelievable amount of snow. If you purchase forks, rear weight is required. I have a modified 3 point ballast weight box for Kubota, for use with TITAN brand forks.
