I use a rear blade on my L3400 HST 4WD for snow removal. This setup has been fine for most of the snow falls in Virginia. But it is almost ineffective in snow blizzard situations with snow 12-24 inches or more, which we have once every several years or so. My asphalt driveway is about 700 ft long and in the open. I am thinking about getting a 72" FEL clamp-on blade from DR similar due to its ease of installation. The cost is about the same with the NorTrac 5ft 3pt PTO snow blower. I would like to have your opinions of your experience with these attachments. The blizzard few years ago, I had to call in a big commercial tractor and it tore up my driveway, and again this year, it really torn up. BTW R4 tires on the tractor. Hope to hear from you soon. Thank you.
