Leaf blower and an extra battery if you go electric
Quick hose connectors for all hoses and spouts
At least one pocket hose. Its sooo light weight and compact that have a couple around for random needs.
I've done this before and recently here some suggestions and advice:
Price compare using Google Shopping: Google Shopping
You can use keywords or specific brands and sizes but it saved me a BUTTLOAD of money.
When you have a choice of colors choose black. Powder coated, plastic color, bridle hooks, saddle racks etc, get black. Its usually cheaper than colors, and to get splashes of color decorate elsewhere. The only exception to this are colored buckets for horses that get supplements. Everybody has their own colored bucket, or a black bucket with a colored piece of electrical tape on the handle with their name.
However many bridle racks you think you need in your tackroom, double it, and if you have the money, triple it.
In my private home barn where I keep my tack, I have two horses and 17 bridle racks and I still wish I would have bought more and planned more space to accomadate even more. And again this is a tack room for only the two horses I keep at home.
You can seem them in my post here: Tack Rooms
If you can't afford a ton of bridle racks, I find the larger cat food cans with a single nail hammered right through the center work just as well, you can even paint them to match the rest of your hardware.
I was REDICULOUSLY excited when I bought my first horse farm, and I wish I would have spent as much time planning my mud and manure management as I did shopping for the stuff I need.
It's not as fun, I've spent 5 times more on mud, manure and pasture management that I did on setting up and equiping a full barn. Plus you set up a barn once, mud, manure and pasture are ongoing and forever.
So my number 1 piece of equipment to invest in is a bunch of hoofgrid or stablegrids installed around all heavy traffic areas Introduction to HoofGrid™ equine footing and flooring grid systems Home
