I just purchased a 1963 D 17 series III tractor with after market 3PT. I also purchased a 7 foot SW842 Sidewinder brush hog. My problem is that they won't hook up. If the drive shaft is hooked up then the lower arms on the 3 pt. are to short and won't let out any. If I hook up the lower arms on the 3 pt. and leave the drive shaft unhooked then the top link adjusted up all the way is still to long and when you lift the hog only the front end of it will come up.Do I need to get a different 3 pt. hitch or is there another way around this to make it hook up so I can use it? |

| Sounds like you need to shorten driveshaft, not unusual. Leon |

Probably a different top link would be what you need I have a bunch of different length top links to fit the tractors/equipment nothing 'standard' about them. |

Since you are putting a new piece of equipment on an older tractor, hook it up with no drive shaft attached, and see if it lifts level, alt he way up. If it does, likely its the pto shaft that needs trimming. Here's the best video, I have seen on the subject: [TUBE]http://youtu.be/0vBFJcvs5SE[/TUBE]

| make sure to have a overrunning clutch on the pto shaft so it does not tear up the tractor |

| If your three point is 14" from the end of the pto shift to the eyes on the end of the lift arms and your pto shaft bottoms out you need to take the shaft apart and trim both halves of the shaft. The top link should be adjusted so the bush hog sits slightly lower in the front than the back when in the cutting position. You'll need a shorter top link to lift the bush hog. At 8' it's a CAT 2 implement. Either use a limit chain or stop to limit the lift arm drop to the height you want to cut at. The 14" measurement is the industry standard for a Cat 1 implement. All recent production tractors should meet this measurement. When you buy a new implement on most of the time you'll have to buy the PTO shaft that fits your tractor. Used implements come with the shaft that fit the last guys tractor. When you trim the shaft make sure you take enough off so it won't bottom out bottoming out the PTO will destroy either the gear box or your tractor. |

Strongly recommend downloading a manual for the cutter from their site. They will list guidelines for how much inner shaft is required to be in the outer portion for proper (safe) operation. You need to measure it out so not binding when up but leave enough to properly handle the torque while set fully down at cutting height. Sounds like cutting the shaft to length and a different top link adjuster may be in order. I do not run mine (SQ172) engaged while fully raised as the angle raises cane on the U-joints, something to remember if you ever end up in an "angled bind" while cutting in rough terrain as you can tear up the cutter plus do major damage to the tractor internals by slamming the tractor PTO shaft forward. |

A quick hitch connected to your 3 pt may solve the problem. I have the same issue with my series 1. Using a quick hitch will set the implement back 3-4 inches from the 3 pt arm connection and allow more room to connect the shaft ------------- D17 Series 1 Allis B- 1939 Allis B- 1945 |

Smoke, One thing I learned with my bush hog on my D-14 is, a rigid top link can be a problem when you are on uneven ground. If the front of the tractor goes up, the top link goes into compression and can bend the bush hog connections. I replaced the top link with a piece of chain. No more bent arms. When the bush hog is raised, it works just like a rigid top link. When a rigid top link would go into compression because the tractor front goes up or the bush hog tail wheel goes up, the chain goes slack. Hope this helps. Bob@allisdowneast ------------- I used to think I was indecisive, but now I'm not sure. |

| I 2nd the use of a heavy chain to replace the top link, it gives the brush hog more ability to float on uneven ground. Someone had already done that on my unit when I acquired it. |

| If you can find an old AC bush hog top link rooster comb, v bar, and chains, its the best set up for ANY bush hog, mounted on an AC snap coupler conversion... |
