Whoa - hold on there rScotty. You were doing just great until you explained why people went from rear blade to something else. I have a mile long gravel driveway that needs snowplowing at least two or three times each winter - some winters - a whole lot more.
I started with a brand new Ford 1710 4WD in '82 when we moved here. I only had a rear blade in the beginning. Then I got a 3-point snow blower along with the rear blade. This unit probably weighed around 2600 pounds. It was light enough that I could not plow the frozen berms that would develop on those winters when we got a lot of snow. I needed the 3-point blower to clear the berms and keep the driveway from "pinching in". Essentially the berms would get so high that I could not go fast enough down the driveway so that the rear blade would expel the snow out and over the frozen berm.
I HATED the 3-point blower. It was s-l-o-w and required some very awkward driving positions. Without exception - when I had to use the blower - I ALWAYS ended up with a stiff neck, sore shoulders and most often a sore back also. To clear the driveway, mailbox area and yard - with the blower - a four hour job.
Doing the exact same job with the rear blade - a hour and a half job.
So.....for the snowplowing and summer driveway maintenance and a couple other heavy projects - in 2009 I traded in the Ford for a 2009 Kubota
M6040. The way my Kubota is set up right now with the heavy Rhino rear blade, Rimguard filled rear tires and the heavy duty Land Pride grapple - it weighs 10,100 pounds.
The beauty of this setup - I plow my driveway in the winter, with my heavy rear blade, and can remove the berms - no trouble - with this tractor setup that is probably four times as heavy as my initial Ford was.
Bottom line - - if your tractor is heavy enough - doesn't have to be 10K# either - you can easily plow your driveway with a rear blade. You don't need anything else. AND, BTW, I no longer get stiff neck, sore shoulders or back using my rear blade. Just wait until the driveway freezes up good and hard - drop the blade and off I go. If I need to plow and the driveway is not yet good and hard - reverse the rear blade and simply drive forward. Works like a champ in reverse also.
