you will have so much extra water you will need to build a water wagon to transport it around your farm for spot watering those plants and trees that are too far from your water delivery site.
You want a "Green" water wagon, so let's build one out of scrap bits we have on hand and make use of the 3 r's... Reduce, Reuse and Recycle. Let's make it strong enough to tow behind your garden tractor and simple enough to make it a nice weekend project.
Enjoy this instructable and don't forget to rate it and let me know if I can make it better.
Step 1: What you Need
The picture below shows the parts you need and serves as an assembly guide.
This project requires some welding and metal cutting, so if you are not up for that, you can just take the picture and measurements to a welding shop and they will have it slapped out for you in no time.
The most difficult parts to acquire are the wheels. They have to be strong because you will be towing around over 600lbs including a full water barrel so bicycle wheels and hand cart wheels etc. are too flimsy for this one. I would not even opt for wheel barrow wheels due to the heavy weights the bearings will see when you bounce the rig over a few potholes.
I scored some scrap motorcycle wheels and they are perfect as we shall see later, except that they have odd size bearings, but if you are handy and have a metal lathe you can make your own axles or just go to the local steel shop to buy what you need.
The water tank is an old plastic barrel with a screw in bung, surplus barrels are available for 5 bucks in my area.
The only new item I bought for this project is the trailer ball coupler. I could have used a draw pin hole on the trailer tongue, but it's much easier to hook up a full water barrel using a commercial trailer ball coupler and my garden tractor has a ball on it so that is the way to go if you can.
One word of caution. This rig is heavy when loaded, so build it strong and make sure your garden tractor is up to the task because you can easily die, or at least have a very bad day, when a 600 lb. wagon runs over you or your family or your pets or neighbours' Lamborghini...
This design has worked well for me for quite a while, but I accept no liability or responsibility for any damage if your version fails on you somehow. Remember water is heavy, so chock your wheels and drive carefully, never exceed Mach 3.2 on your garden tractor...
