This build required us to mount a 50 litre 12v sprayer to a John Deere ride-on mower. We mounted a 2m Noble Adams boom to this frame work. As with most of our builds like this we made the unit so it was easily removeable from the lawn tractor (approx 1- 2 mins).
This type of sprayer is perfect for the customer with a large lawn, that has a ride-on and doesn't want to spend a fortune to get something that is easy and simple to use.
Requires a lot less effort than using a knapsack for the job.
This is just an example.
