Bare with me.... reviving this thread because it was very informative to me.
I never heard of a pendulum spreader or a drop spreader for tractor. I need to upgrade my spreader for a 1/4 mile steep (12% grade) driveway. I use a mix of 4-way limestone chips and salt. The ç”°hips are 3/8?1/4 in size with some larger gear and there. Tractor has rear and front remote hydraulics.
Looking forward to recommendations.

As LouNY has so kindly mentioned there are many options.
I helped a friend in Ohio pick out a high quality pendulum spreader from VICON that he mounts
on his three point hitch and loads by hand since it is lowered to the ground.
His sons fill supersacks with gravel sand using the front end loader holding the bag up and he keeps
them in a heated garage-the super sacks not the rug rats haha to quickly enable them to load the
Vicon spreader with both sand and salt and it works very well.
He uses the short salt sand spreading tube attachment to cast the sand/salt mix on his driveway
and it works very well.
Limestone chips will cause excessive wear in any spreader UNLESS its a wet lime spreader and will
be difficult to spread when frozen.
Using gravel sand and salt would be a better option for you if at all possible to enable you to use a
high quality of spreader like a VICON pendulum spreader.
Decide how much money from your disposable income you can spend before you buy anything as
the more you spend the better the quality, steel thickness and ability to tolerate the abuse from
the use of a hard rock based material.
A VICON pendulum spreader will not tolerate a broken/jagged material like Limestone chips due to its fiber glass
hopper so keep that in mind.
If you use a sand and salt mix A VICON pendulum spreader will out last every tractor you mount it on as it is well
designed and built agricultural implement that has been in use for over 5 decades worldwide that uses a cast iron
gear box and agitator arm to break up any clumps of material that need to be spread.
A very large HERD sand spreader like the 1200S model will tolerate what you use for a traction aid and it will require
annual maintenance for sanding and painting the interior of the hopper UNLESS you line the interior of the hopper with
a UHMW blue stripe plastic sheeting from Horn Plastics to protect the hopper interior and maintain a slick surface to
prevent bridging and sticking of the material.
The blue stripe plastic sheets can be easily cut to size and bolted in place with carriage bolts and bolted through the hopper walls.
Decide how much you can spend before you make any decisions and you should use a decision tree and the Ben Franklin closing
argument adding up the plusses and minuses before you advance further.
As you are using this specific material you should also look at using a flat bed trailer with a fiberglass or injection molded salt spreader
with either an auger or flight chain floor scraper to spread this material. The one thing to keep in mind that you must do is be sure to
empty it every time you use it to prevent the flight chain from freezing to the floor of the hopper.
The same rule of thumb applies to a HERD or VICON spreader and if you can store the spreader and tractor in a warm garage all the better
for you as you will have many fewer problems with the tractor and spreader.
