I am starting to ask around and here are some favorite things from my horse friends:
Dynamite Wound Balm. It does really smell bad, but it works on just about anything. Even humans. I couldn't find a picture, but you can find it at the Dynamite website. They have other good stuff there too if you are not familiar with Dynamite find a distributor and try it out.
Contractors 2 wheel wheelbarrow. Great for lots of manure scooping. She says she could get 3 days worth of Soda manure out of his paddock and he is a 17.3h hanovarian gelding!
Muck Bucket Cart. I had one of these and ABSOLUTELY loved it. I lost it a couple of years ago and haven't replaced it, but it was a great item. You can buy the ones that don't collapse flat, but then you might as well take a wheelbarrow. Spend a few bucks more and get the one that folds flat. It is also great for the barn because it can fit a bale of hay or 3 or 4 bags of grain. You can buy them online at most of the stores, but I bought mine locally, with the cost of shipping, it is probably worth it.
Hose End Nozzle with several settings. This is a great item to have anywhere there is a hose. The different settings can help a horse who isn't comfortable with water be bathed easier (shower setting), or just to cool off (mist). To fill water buckets I use the fastest one, to clean out the shower stall I use the cone adjustment. And don't forget to take it with you trail riding or horse camping. There are often hoses, attach this to the end and mist yourself off on a really hot day! I love it and so do my horses!
