Theres a wealth of information and great shop tricks
Here are a few that come to mind
If you can't find the proper raditor hose and yours has a punture or a split in the middle cut the middle out leaving about 4 inches of both ends and replace it with a pice of clean exhaust tubing you can bend it to whatever shape you need then add to clamps and your done let a stick try to go threw a piece of pipe.
Old military ammo cans are great for so many things I put bolts in one and nuts and washers in the other, if you can find the really large cans they make great tool or chain boxes for your tractor or ATV and best of all there water proof too.
I get paid everytime I clean my shop I have a small trailer I back up to the shop and fill it with all the scrap iron and alluminum I no longer can use as well as brake drums and heavy wore out parts then take it to the recycleing center, last time I clean the shop I made 35 bucks.I do this about 3 times a year, I have made good friends with the center and now I get a discount for buying steel there. its a win / win
Not so much a trick but just as useful I made a weight box out of a 4 foot long 10inx10in 1/2 thick square tubing weighing about 100lbs by itself stood it up and down and welded a cap on the bottem, filled it with sac crete/ bag concrete added a 3pt pick up to it then I got creative with D rings for pulling, and 2 inch reciever for a trailer ball and Hooks the concrete setted and left 2 inches at the top so I have a good piece of chain in it and the hooks on the chain slide on the edge of the box for easy quick use.
If you need a plumbers snake for you spetic tank and you dont want to spend the money a garden hose with a cap/plug on it, works great insert it and get it going then turn the water on it will firm up the hose since the cap is on the other in and you can push out the clog. You can do the same thing with an air hose but without the cap when you feel the clog you can blast air into the clog if need be too. Please clean your hose after with those neat clorox wipes. I used this one 2 weeks ago.
Times are changing and parts cost more than whole pieces of equiptment and cars/trucks for that matter. I am a keeper and hate to part with anything but running the numbers I had a truck that was going to cost me $3,000 to fix and then the truck would only be worth about $2500 when I got done. So I sold the truck for $2500 as is. I have found another truck for $3,000 and drove it home. Now I would not nessarlly do this for my everyday driver but for a farm truck or a piece of equiptment it was the best thing I could have done. If a new gear box on your bush hog cost $450 and you need blades to check out craigslist or your local paper in you aera I bet you find a good mower for less. then scrap the old one for the metal and make a few bucks.
