I got a good deal on a Buyers mini salt spreader last year, & didn't even use it. I still have less than 5 places that need salt when the ice comes.
Go to local TSC or farm & fleet & buy an EARTHWAY spreader. They are the red-colored brand. I picked up one for $20, & it holds almost a 50lb. bag of salt. They do make a bigger one for 40-60 that'll hold a little more.
I bought an Agri-fab push spreader for about $110, & the $#@&%@! wheels rusted shut after the first winter, & I washed it clean after each use. They only give you a 90 day warranty if you use it for salt, & that's why. It's a POS. My buddy bought one & same thing happened to him too.
The earthway doesn't rust up, & spreads well.
Of course, if you have big lots or many lots to salt this prob. will be like mowing 3 acres with a push mower.
But for what I need, it's great. It paid for itself the 1st time I went out, & just used it the other night, 3 yrs. later. I do my salting out of our caravan; it fits in the back & I don't have to fire up my gas-guzzling 4x4 to run my route all the time.
I'd even buy one just for sidewalks or for backup; heck, for 20 bucks how can you go wrong???
