Using Correct Hitch Category

IMPORTANT: Excessive power can damage an implement and too large an implement can damage the tractor.

Correct clearance must be maintained on implements when attached to the three-point hitch of the tractor. Use a combination of attaching points to achieve the following recommendations.

Measure implement attaching points:

Measure distance between lower hitch points (ball centerline).

  • Cat. 3N implement distance is 870 mm (34.25 in.)
  • Cat. 3   implement distance is 1010 mm (39.75 in.)

NOTE: Spacers may be required for lower hitch points. See your John Deere Dealer.

Measure vertical distance (mast height) between upper hitch point and lower hitch points. Distance must be 685-885 mm (27-34.8 in.).

IMPORTANT: Interference or damage of front draft link attaching points can occur if dimensions of lower hitch point span exceeds 1010 mm (39.75 in.) and /or if draft link bumpers are incorrectly positioned. (See Converting Hitch Category in this section.)

Interference or damage to tractor SCV's can occur if mast height exceeds 885 mm (34.8 in.)

See your John Deere Dealer if implement measurements exceed recommendations.

Set tractor attaching points to match implement measurements.
