Congrats on the new tractor! As others have already stated, hairpins & other pins & eclips are necessities - I would also keep a couple spare drawpins for the cutter. My minimal toolkit for out in the field would be my 4 lb. drilling hammer(short handle), a 12" or larger adjustable wrench, needlenose & slip-joint pliers, screwdrivers, a crowbar. I keep a major toolbox in my truck as I use my tractor commercially and still don't always have what I need in a particular situation. I would recommend a couple of other tools in your truck - a 1/2" drive set, especially an 1 1/4" socket and breaker handle for replacing drawpins in implements, and a good pipe wrench to go with it for that same purpose. If you do alot of cutting, you will bend and/or break drawpins and also they loosen-up and need retightening. My greasegun comes out of the truck every single day I run the tractor - I have the pistol grip style, and keep a case of grease cartridges. If you don't have compressed air at your property, a portable air tank with a blowgun will help keep the radiator clear - this is a must with cutting so much. Water doesn't work as well as air, but it would get you by. Be sure and watch your temp. gauge after a couple hours of cutting, use the blowgun from the engine side to blow back out the front of the radiator to get the most out. Wish you the best of luck !!
