3/4 inch Impact Wrench

I have a farm in east Texas and I run several John Deere farm tractors. These machines are fairly large and I need to remove some larger nuts from them. My trusty 1/2 impact wrench just isn't cutting the mustard. I need more power to break these old and rusty nuts but I don't want a gigantic impact wrench either. What is a good size impact for me?

I would recommend a 3/4 inch impact wrench. A 3/4 inch is good compromise between a 1/2 inch and the larger 1 inch models. A 3/4 inch impact wrench should have enough nut busting torque to remove those stubborn nuts and is smaller than its 1 inch big brother. One consideration is if you need the extended anvil. We have several models with a 6 inch extended anvil. This allows to get access to nuts buried inside a wheel rim for example. If the nuts are right out in the open and standard anvil will work just fine.
