Modular-design cutterbar
Modular cutterbarModular cutterbar

John Deere's patented design cutterbar is made from individual, diagonal-cut modules.

Serviceability is easy. Modules can be removed individually while leaving the cutterbar attached to the frame.


Made of high-strength nodular-iron castings, each module consists of two idler gears and one drive gear. The large-diameter idler gears transmit power from module to module. The idler gears turn at a relatively slow speed for added durability.

The smaller-diameter pinion drive gear is used only to power the cutting disk. Power is not transmitted from one cutting disk to another except through the large-diameter idler gears.


The modules are interchangeable. Disk rotation is determined by the position of the quill (A). There is a rubber oil seal between each cutting module.

Equal-angle hitch
Drawbar equal-angle hitchDrawbar equal-angle hitch
Drawbar extensionDrawbar extension

The drawbar equal-angle hitch is optional equipment. This hitch option includes:

  • Ball-joint hitch—to be installed on the mower-conditioner tongue
  • Tractor hookup
  • Drawbar extension—to be installed on the tractor drawbar and adjustable with one wrench

The drawbar equal-angle hitch is designed to be towed by a tractor only, and includes a screw jack and safety chain.


Turn limiters may be required to prevent powerline damage if the hitch point of the tractor is beyond the rear drive wheels of the tractor.

An overrunning clutch is located near the platform gearcase. This design enables free rotation of the tractor hookup for easier attaching to the tractor. 


A slip clutch is incorporated into the overrunning clutch to provide protection to the platform.

Clevis hitch

The clevis hitch is in base equipment. This design attaches directly to the tractor drawbar for operator convenience. The heavy-duty clevis design provides a strong attaching point to the drawbar.


For added convenience, the hitch-pin retaining bracket can also be used to store the PTO shaft when the machine is not attached to the tractor.


The clevis hitch is designed to be towed by a tractor only and includes a screw jack and safety chain.


Turn limiters may be required to prevent powerline damage if the hitch point of the tractor is beyond the rear drive wheels of the tractor.

Impeller conditioner
Impeller conditionerImpeller conditioner

Impeller conditioning is standard equipment on all John Deere mower-conditioners.


Proper conditioning in a wide range of crops can be achieved when the conditioner is properly adjusted.


The impeller conditioner works well in legumes, especially alfalfa and most all-grass crops. Impeller conditioners are not recommended for thick-stemmed or cane-type crops, such as sudan or sudex, or crops over 5 ft tall.

How an impeller conditioner works:



1. As hay is cut by rotating knives, tines pick up the plants and carry them through the machine:

  • 33 V-shaped tines are on the 625 MoCo; 45 V-shaped tines are on the 630 and 830 MoCo; and 57 V-shaped tines are on the 635 and 835 MoCo.
  • Tines are free swinging to reduce damage to the conditioner if rocks or other solid objects are struck.

2. As the plant passes through, it rubs against the conditioning hood (A) and other plants:

  • Scuffing action removes the waxy surface from the stem of the plant to allow faster evaporation of moisture.

  • Conditioner hood opening is adjustable to accommodate various crop volumes.
  • Crank handle allows an infinite number of adjustments between the minimum and maximum conditioning levels. The closer the hood is to the tines, the more aggressive the conditioning.
  • Conditioner position indicator provides an easy reference point to control the degree of conditioning.

3. The speed at which the tines rotate will also affect the degree of conditioning. Two impeller speeds can be achieved by interchanging the upper sheave (A), located under the shield, and the lower sheave (B).

  • With the sheaves in the position shown, the impeller turns at 870 rpm; this is ideal for grasses.
  • If the sheaves are reversed, the impeller turns at 630 rpm; this is ideal for legume crops.
Windrow formation
Handle for forming-shield adjustmentHandle for forming-shield adjustment

Forming shields are easily adjusted to control material flow. This allows the operator to match the windrow width to harvesting requirements.

Handle for swathboard adjustmentHandle for swathboard adjustment

A swathboard is in base equipment for additional control of the windrow formation (for 630 and 635 MoCo models only).

Windrow width* is as follows:


62578.7 cm to 149.9 cm (31 in. to 59 in.)
63088.9 cm to 198.1 cm (35 in. to 78 in.)
63599 cm to 238.8 cm (39 in. to 94 in.)

*Depending on crop conditions.

Rotary disk cutterbar
Rotary cutterbarRotary cutterbar

The rotary cutterbar is designed and built by John Deere. Large oval disks with free-swinging knives are used to cut the crop.


All cutting disks are the same and are computer-designed for improved wear and cutting performance.


Cutting disks are made of high-strength austempered steel to ensure the steel is thoroughly and evenly tempered for good wear characteristics.


The disks rotate to give a knife-tip speed of 307 km/h (191 mph) for clean cutting.


The knives are free-swinging to reduce damage if a solid object is struck, and they are reversible to double the useful life.


The knives are removed at the front of the cutterbar for convenience.

Wear caps
Wear capsWear caps

Made of austempered heat-treated ductile steel for excellent wear characteristics, wear caps are installed on each end of the cutting disks (except on the end disks where crop accelerators are used) to increase the wear life of the cutting disks and knife-bolt nuts.


Wear caps are open on the end to prevent debris from packing in close to the nut, making hardware and knives easier to change.
