Solo Backpack Sprayer with Piston Pump, 425 is rated 4.4 out of 5 by 14.
Rated 5 out of 5 by from Excellent sprayer Excellent backpack sprayer. Replacing one that was purchased at least 20 years ago. Easy to use. good pressure for all spraying around farm and home.

Rated 5 out of 5 by from Backpack sprayer This sprayer is great. The adjustable nozzle lets you control the spray area and concentration, and you can just keep pumping as you spray to build up the pressure without stopping. The cannister sprayers take a lot longer because you have to stop to pump them up, and they don't hold as much.

Rated 5 out of 5 by from Excellent sprayer Comfortable with fan nozzle, I can easily get sharp edges and clean fencelines, valve boxes and around benched. I have used most sprayers on the market over the last thirty years and Solo provide a professional result when used properly and cleaned regularly.

Rated 5 out of 5 by from Gets the job done. I've been using this type of backpack sprayer for many years. I just bought this one from Tractor Supply since they had a very good price. This is the fourth one I have owned....They last about three years with little care, probably would last longer with more care (maintenance). I mainly use this sprayer to take care of about a dozen fruit trees I have plus a few other spraying needs around the garden.

Can I ride this in a cart instead of wearing it?

Asked by: Fe Fe
There shouldn't be a problem with this application, though we would suggest strapping this to the cart to prevent it from tipping.
