An innovation unique to Kelly Engineering is our Disc Mulching range of Chains. Designed initially for managing stubble residue, the disc chains are now used for everything from primary tillage to planting poppies.

The mulching chains are used with the primary aim of returning crop residue to the soil. They roll down stubble and chop and split it into smaller lengths allowing weathering and microbial breakdown to accelerate.

In the right soil types the mulching chains can cut up to 100% of weeds. The cost efficiency of this operation means that integrated weed management incorporating a full cut is once again a realistic proposition.

The chains also perform a valuable role in preparing a seedbed in fields that have been ploughed and left cloddy and rough. The Disc Chains are an excellent tool for leveling and filling in wheel ruts left by harvesting or spraying equipment. Fields can be prepared for planting quickly and cheaply, the shallow tilth being ideal for drying out the surface and increasing soil temperature in the Spring.

Air Seeder kits for small seeds or coarse grains have been fitted and used to great effect. Large areas can be covered in a day very efficiently. Maximum use can be made of moisture establishing crops at optimum times to enhance yield potential.

Parts Manual

Kelly Diamond Harrow with Corn and Soybeans in Missouri


  • Early and cost effective management of stubble
  • Cost effective seedbed preparation
  • Shallow tillage
  • Stimulate germination of weed seeds prior to pre planting knock down herbicide application
  • Level wheel ruts and rough fields in the Spring
  • Early access to fields to start crop preparation. Dry out the surface and expose dark soil to the sunlight for soil temperature management pre planting.
  • Dry out Rice Stubble quickly for a complete burn in the Fall. Mulch Corn Stubble in the Fall to return organic matter and nutrients to the soil as valuable Humus.
  • Crop establishment in conjunction with an air seeder or broadcaster
  • Chemical and fertilizer incorporation

The mulching chains are made from heavy chain (1.4" diameter steel in the links) with plates welded to each link to form a gang of discs. The plate is hard wearing and heat treated for toughness and abrasion resistance. Concave discs make the chain aggressive and self sharpening while adding strength to the plates.

High grade Steel Tubing and plate are combined to produce a strong and durable frame. Sections include 6"x4" RHS in .2" wall thickness. Over 70 different Profile and Laser cut plates are used to give strength, functionality and a professional appearance. The rugged and reliable frames have been strengthened and improved to withstand the extra stresses encountered with the Disc Chain.

All new parts are used on our machines, including the tires. The larger models, 50 & 60 run on 15.5/80x24 lug tires. The huge diameter gives a smooth and bounce free ride, minimal soil compaction and 12 plys of puncture resistance.

The 40 and 45 models run on 16.5 x 16.1 14 ply ribbed tires. The Wheel Rims have an eight stud centre common to many US farm implements. The Hub is a heavy duty eight stud hub with a screw in grease cap. The spindle is 2.5". Commonly available John Deere and Case hubs and spindles can be used in an emergency.

Folding totally from tractor seat - user friendly. All Models use two pairs of 1/2" ISO standard hydraulic couplings. Larger models incorporate a multi stage sequence valve to manage the folding and unfolding operations. The sequence valve has been upgraded to allow lower operating pressures and greater lifting capacity.
