Sickle Bar Do I really need a drawbar??

[SPYDERLK]

Look into a Ford 501 Sickle mower. If you google this....you can see the hook up. I cant see where you would need a drawbar as long as you can secure the 3 point from side sway.

I have a 501. dont need drawbar. need top link.

Makes me wonder how those drawbars differ from todays fixed/swinging drawbars. They are the safest place to pull from.

The invention of the three point hitch was more for efficiency and the additional traction on the rear wheels on lighter tractors. The MF and Fordson tractors had short wheelbases which increases the rollover backward accidents. The safety factor was a benefit not the primary reason. To say that the majority of death and injuries were caused by implements towed by the drawbar is irrelevant. Everything was towed. Some tractors didn't have seats, the equipment they towed had a rider/operator to control depth, feed rates for seed and fertilizer and sew grain sacks etc.... Falling under the disc or harrow was a big problem.
The point of connection on a modern drawbar is below the rear axle line. This is to prevent tipping backwards.
Some tractors don't have down pressure on the three-point. In effect when the implement hangs up and has no forward motion the tractor three-point will float and allow the rear wheels to keep moving.
Large tractor drawn implements are drawbar attached. They're huge. No tractor can lift the larger ground engagement implements by the three-point. They are assisted by hydraulics and wheels for maneuverability.
Shear-pins on plows and deep soil implements allow a safety and damage control factor,
Adequate front weight distribution is a big factor in prevention of tipping accidents.
Towing a trailer with a drawbar is the correct way. A three-point and bar will allow the center of gravity to move back and also uneven weight distribution can cause the three-point to raise causing more problems.
