  • Boom pole capacity
  • Hey all...I have a '51 8N with a boom pole 3-point hitch. I'm wondering if there are any resources on how much weight it can safely lift? I'm looking to use it for pulling a 454 big block out of my pickup...

  • Tractor hydraulics are not as slow as you may desire. Good for snatch and grab.
    How about your boom pole with a Come-A-Long on the end connected to your engine?
    You can do it slow where you need it and fast where you don't.

  • My Ford 19-52 boom pole has a placard on it with maximum weight limits for different Ford tractors. As marked for the 8n: 475 lbs inner hook; 390 lbs middle hook; 3xx (x indicates unreadable) end hook. NAA: 525 inner; 430 middle; 435 outer(yep its marked 435 outer).

  • Thanks Jeff for clarifying. I was going to get over to the farm again tomorrow and take a photo of my 19-52 Dearborn Crane and set this straight. I always assumed 450# was about the max capacity and 750# was not a good idea. I just wanted the data to back it up. One thing fellas don't comprehend is the front end must be counter balanced with added weight to prevent from what you see in his picture with the front end off the ground. The higher the load is lifted, the higher the center of gravity becomes. Steering will greatly affect the lift too even with added front weight so GO SLOW. I always use STABILIZER (ANTI-SWAY BARS) with my booms. You want to minimize any side to side swaying motion of the load as it can become a dangerous, uncontrollable situation.

  • Obviously the lifting capacity of the tractor hydraulics and not the load rating of the boom. A big block checks in at 600# plus - well in excess of the lifting capacity of any of those tractors. The pole itself is probably close to 1T at the tip and double that at the middle.

  • An N can not break a modern, manufactured boom pole. If it is a home built pole then all bets are off.
    The photo shows my cheap King Kutter boom pole behind a 4000 with added front weights. The tractor itself weighs about double what an N weighs and you can see the pole is well over loaded.
    I don't recommend you lift like this every day but you won't hurt the tractor over lifting with it. You just wont be able to steer - except with the brakes, as your front tires will leave the ground.
    There are a couple of ways to increase lifting capacity with a pole. Both involve keeping the load as close to the tractor as possible.
    First, shorten your top link as short as possible. Second is to lift from halfway up the pole.
    Front weights will increase lifting capacity too. Use front wheel weights or in a pinch, a couple of sand bags draped over the front axle.
    I suspect your N will handle that big block engine just fine if you keep the pick as short as possible..

  • What TOH said. If memory serves me, an 8N hydraulics, to original specs, will lift about 750 pounds AT THE END OF THE LIFT ARMS. A boom pole is about 5 feet past the lift arms. The weight the tractor can lift is dramatically DIMINISHED by the increasing distance from the the 3 point connections.

  • Well within the capacity of most boom poles but you may find the tractor hydraulics can't lift the load.

  • TOH is right on. My 8N wouldn't even handle a 350. Tried it.

  • Re: Boom pole capacity
  • Been there many times and I'II bet like me you figured out how to make it work. If the hydraulics will hold or you chain the lift up you can use the pole as a mobil sky hook and a come-along or chain hoist for raising and lowering the load. That old necessity and invention thingy

  • I just moved the 8N and put a MF275/loader in its place. :) It will lift a complete Toyota Celica off the ground.
