12-Row Front-Mounted Cultivator Folds Hydraulically
Last spring our neighbor purchased a new John Deere 12 row (30-in. spacing) front-mounted cultivator. The first problem he had was that Deere does not manufacture this cultivator to fit any larger tractor than a 4440. The neighbor has a 4640.

12-Row Front-Mounted Cultivator Folds Hydraulically CULTIVATORS Cultivators (58C) 6-3-9 Last spring our neighbor purchased a new John Deere 12 row (30-in. spacing) front-mounted cultivator. The first problem he had was that Deere does not manufacture this cultivator to fit any larger tractor than a 4440. The neighbor has a 4640.
We made adapters to mount the cultivator on the 4640 without "butchering" the original frame. The adapters can be removed so the cultivator frame will be back in its original state for resale, or for mounting it back on a 4440 or some similar tractor.
The next problem the neighbor had was that he could not fold or unfold the cultivator in the field without the aid of another man, a tractor and loader, blocks, and a jack. He would have to pull each side of the cultivator around with another tractor and then either jack or lift the frame onto its latching pins with a loader.
When he wanted to fold the cultivator to move, he needed another tractor to pull each side around in front of the tractor so he could get the transport bars hooked together on the ends of the cultivator.
Af ter several hours of figuring and building, we came up with a hydraulic fold cylinder, and a roller and ramp device which lifts the frame up onto its latching pins.
Now, when the neighbor goes to the field, he gets out of the tractor, removes the transport bars which hold the cultivator in front of the tractor for road travel, gets back into the tractor, then pulls the hydraulic valve while he drives forward slowly. When the cylinder reaches the end of its stroke, he gets out of the tractor, puts in the latching pins, and then begins cultivating.
When he wants to move, he pulls the latching pins, thenpulls the hydraulic lever while he backs up slowly. When the cylinder is retracted, he gets out and puts the transport bars on and drives off.
I think John Deere named this cultivator properly when they called it a model FM 12-30, which must have meant "Floundering Monster Twelve Rows Wide", because that is exactly what it was before we put hydraulic fold on it and the other improvements.
