Directions say to "strap it to the cargo rack on the back of your ATV". So, not really designed for a lawn tractor. But I knew that going in.
On my John Deere lawn tractor, there are two arms that hold the rear bag in place;
Bag removed
The Sprayer frame sat perfectly on those two arms.
Sprayer in place
I bent two flat steel brackets at right angles and bolted thru existing holes in the sprayer frame ... and drilled a hole in each bag arm of the lawn tractor to attach the bracket with 1/4" bolts.
Not trusting those arms to carry the full weight of the sprayer and 16 gals of fluid, I fashioned a bracket out of some scrap that I had laying around,
and attached to the farthest point of the sprayer frame, down at an angle to what looked like a tow hitch hole on the tractor. (red diagonal bracket in photo)
Finished Sprayer on Lawn Tractor
Seems pretty solid and the entire system can be removed with 4 bolts. So a 5 min job.
Also just ordered the mulching kit for the tractor so I won't be using the bag again until the leaves fall.
I gave it a whirl today. Mixed up the chemicals and made 6 gallons of eff u weeds cocktail.
The sprayer worked as advertised and I felt like I was a crop duster. Went nice and slow to be sure I got a good coating on all those nasty weeds.
I went thru the 6 gal pretty quick just in the back yard.
Mixed up another 12 gal and got back at it. Front yard is a little hilly and the steering got a bit light in a couple of spots ... but no wheelies.
I may need some ballast on the front if I go the full 16 gal but jury is still out.
The wand came in handy too where the wife has flowers and around the deck where I didn't want any over spray.
An easy to reach lever on the pump cuts flow to the crop dusting boom when I need to use the wand.
Overall pleased with my purchase. Now just need to wait a couple weeks and see how much it helped with the weed situation.
