A Guide to Salt Spreaders, Grit Spreaders and Rock Salt Spreaders from Gardenlines
If you want to spread rock salt then you will need a specialist high-output spreader preferably with a stainless steel frame. Rock salt becomes clogged in the hopper very easily, especially when damp, and is notoriously difficult to spread. Rock salt is also corrosive and will make your spreader rust more quickly unless you clean it out thoroughly and keep it dry after every use.
Free-flowing, dry ice melt and white processed salts will spread more easily than rock salt. They can be used in a spreader in the same way that a fertiliser can. Although more expensive than rock salt per kilogram, ice melt can be more economical because you can finely adjust the flow rate so that you use less product per square meter.
Please see our blog post ‘Choose Ice Melt and not Rock Salt or Grit Salt for your Winter Spreader’ to find out more.
Types of Salt and Grit Spreaders
These spreaders will spread your salt by means of the salt falling onto a rotating disc which casts the salt far and wide. The flow rate can be adjusted using a lever on the handle – but remember you need a large, high-output aperture to be able to spread rock salt.
If possible choose a spreader with a stainless steel frame and enclosed gearing so that it is less likely to corrode. Pneumatic tyres, as opposed to solid ones, are also useful because they have a better grip in icy conditions.
Towable spreaders work in the same way as push spreaders except they can be attached to a ride-on mower or quad bike and towed. Some push spreaders, such as the new EarthWay Flex Select range, can be converted from push to tow so you can have the best of both worlds.
Vehicle mounted salt and grit spreaders are suitable for more heavy duty salt spreading work. These salt spreaders will spread rock salt and can be mounted on fork lift trucks, most 4x4 vehicles or towable trailers. These rock salt spreaders include covers to protect the contents from rain and snow. The capacity of the vehicle mounted rock salt spreaders is much larger compared to regular salt spreaders due to the nature of the work they have to do. These are suitable for mostly commercial use.
Which Salt Spreader is Suitable for You?
Consider the size of the area that you want to cover. If you have a small area to clear then a push salt and grit spreader will suit you. If you have a larger area to cover, and have a ride on lawn mower or tractor, then you will find that a towable salt spreader will get the job done quickly. If you have a huge area to clear consider a vehicle mounted grit spreader.
Consider what you want to spread. Do you want to spread rock salt or an ice melt? To spread rock salt you will need a high-output spreader, preferably with a stainless steel frame. To spread dry, free flowing ice melt and white processed salts, then any general broadcast spreader will be suitable.
