What's an appropriate price for a John Deere 40 crawler in good condition? Will a crawler of this size push over trees that are four inches in diameter?

The bigger stumps (stump w/ tree) push over easier if they are pushed over before the tree is cut. The extra weight of the tree helps push the stump over once you get going. Once it is going over, the weight of the tree, still attached, keeps the tree stump from settling back into its original hole or spot. Thus it is then easier to get the blade under the stump and push it over the rest of the way.

Good luck .. I paid $3000 for a 420C. A little fixing and paint and it pushes with the best of them.

I want to express my appreciation to Tony and Ron for your comments. They are very helpful. I'm grateful that you are willing to share your knowledge and experience with me. If I decide to purchase the one I referred to, I'll try to let you know how it turns out. Thanks again.

Russ I purchased mine for $3000 US last summer. Not running and motor was seized. I have taken it apart right down to the transmision and gears changed all the seals and bearings as required. I have seen them in good shape for about $5000.00 US but at times unless you know what you are looking at you still may have problems. Most of these units were over worked and had one of the final drives broken. These engines used a bypass oil filter system as well. Meaning that when the engine is started what ever is in the pan goes through the bearings and the over pressure is filtered. On the bottom of the drive housing is a drain plug which is part of the dry steering clutch. Try and remove them along with the final drive plugs and see the condition of the oil. In the dry section if water pours out your into some work cause everything is getting rusty. You can also open the access cover on the top of the clutch and break mech. box It has 4 1/4 20 bolts and is square. Look inside and see if everything is free. Some surface rust is no big deal. Depending on what type of track on the machine with a small blade it will push over a 4" tree. Theses machines have a 100 cubic inch motor rated at 21 horse power. Lots and lots of torque. That is why the final drives would blow. Also check the chains at the pin bosses it they are mashed then some major money will be required to repin and rebush the track chains. Sprocket, look for uneven wear in the teeth. Any other questions just let me know.


Tony.

Russ, forgot to mention - check the bottom of the roller assembly frames, they should have about an inch clearance on the track pads to be sure the roller bushings are in good shape. Price ? Depends totally on condition, and how much work it can do for you. Also strongly recommend some type of operator protection BEFORE you start pushing over trees !

Russ, shouldn't be a problem. They are like everything else, you have to get some experience operating it, then it will do things you wouldn't have believed. You'll probably have to hit the tree high, then back up and get the hlade into the roots. Can't see you having a problem.

In addition to Ron's very good advice. I've seen my Daddy push dirt away from the base of the tree (which ever side the tree is leaning) and cut a root. Then push the tree up high like Ron has written. Have fun!
