I live in Ontario Canada on 3 acres of woodland but my access lane way is 1/4mile long with VERY steep hills. I need a tractor with a front mounted snow blower to keep the road open in the winter. My local Kubota dealer is recommending the B2320, B2620 or B2920 model with snow chains for climbing the steep hills and a front end loader. I am finding it very hard to get detailed info on the differerent models of snow blowers available from Kubota. Their web site has no info on blowers for these new models. I understand that my three options for blowers are the BX2750A at 48.75", the B2781 at 50" or the B2782 at 60". I prefer the larger 60 inch width but want to make sure I am buying enough horse power (mid PTO) to power the snow blower. So which model 23hp, 26hp, or the 29hp is right for me? The Kubota brochure lists the PTO horsepower for each model....are the rear and mid PTO horsepowers the same? I did notice that that mid PTOs on all three models have the same RPM (2500 rpm). Anyone have any experience with these models of snow blowers? Where can I get more info on the blowers if Kubota doesn't have any on their own web site? Anyone have experience climbing VERY steep and icy hills with chains. Thanks in advance for your thoughts
