Well, we had some pretty bad flooding in the stream behind our house last winter due to what seemed to be an Ice Jam. It dislodge a very large boulder from the stream bank and dropped right into the middle of the stream. It turns out the real cause was a friend had her kids over to play with my daughter, and they thought it was fun to throw some of our nicely seasoned hand split maple firewood into the stream to see if they could dam it. (They did).

In any cause I had to get the boulder out. I tried to pull it out with a chain on the back of the tractor on the three point hitch spreader, and pulled a wheelie. I was not able to get above the boulder. I tried a chain on the loader but it did not have enough capacity to lift the rock. So it sat for a while.

Looking at the Tractor supply website I saw the price of the rear lift boom for the 3-point, their house brand Country-Line was only $99.99 plus a $5.00 discount coupon. That is about 1/2 price. The closest TSC was sold out but one about 45 minutes away had one left. It was listed as having a capacity of 500 lbs but one of the reviews on the website said it was better for more. Off I went with my 8 year old after breakfast bribing her by allowing her to get one of the small Schleichョ animals they sell.

It turns out the boom which has Cat. 1 pins is 21" Cat 0 spacing. which fits my BX1850 without having to reverse the pins.

I got the chain all rigged up for the lift and about all that happened was the front of the tractor went up instead of the rock.

I unshackle the chain from the boom and go in search of a rock I previously moved a couple of months ago that was right at the loaders limit of about 400-500 lbs. This time as the bucket went up the front tires went down. I checked and they were down to 14 lbs. Crank up the compressor and fill them to 24 PSI. Get the rock in the loader and going up the hill to the stream we come to a stop as the weight transfer to the from axle lifted the rear wheel of the ground since the weight box was off to put the lift boom on. Engage front axle and away we crawl.

Hook the chain to the lift boom and finally, the rock gets up about an inch, not enough to clear the edge of the stream bank. This is one large rock. OK, Time for drastic measures. I raise the front end of the tractor off the ground by lowering the bucket to the ground with the rock still in the bucket and a bit of down curl to the bucket. This slacked the rear boom chain about 4 inches and allowed my to come up on the 3-point another 4-6 inches. When I then raised the loader off the ground the front end came down and the boom came up to a total of 6 inches enough to get the rock out of the stream. Now I just had to creep a couple of hundred yards to my rock dump. Finally success.

I did get a couple of pictures but they do not express the full scope of the move.

My daughter did come out to help with her tractor, fully dressed for the part down to her sparkling pink slippers. I had to include a couple of pictures of her with her tractor dressed for a hard day of work. She is very proud of her tractor and uses it as part of her dress-up. Have a great holiday weekend. - Scott

Tell that little lady to drive with her bucket down... safer that way. ;)

In spite of having bigger tractors, I often found myself using the BX2660; very capable tough little machines.

Looks like you're a two tractor family:thumbsup:

I think we've all missed the key point of the story, the fact that the mini-boss was smart enough to dam a river with fire wood.

Good for her, an engineer in the making.

Scott,
There's another 'trick' you can use. Get a long chain, tie one end to a tree or heavy object and the other to to the tractor hitch. Loop the middle over the rock and pull away. That will reduce the pulling force to 1/2 of the force to pull the rock out directly. Not really a trick, just simple physics.

careful when lifting rocks . I had one suspended from the front bucket and got it out of a hole ok, but when I backed up the right rear wheel hit a rock that started my suspended rock swinging. That was when I abandoned my seat and ran for it. The momentum of the swing took the tractor over. Next time, I will not lift, but drag the rock.
