A better seedbed
for a better bottom line
Kelly by name...
...innovative by nature
Based in Booleroo Centre, South Australia, Kelly is
a family owned and run business, with national and
international presence. Kelly has a farming
background, which offers a unique understanding
of the reliable and versatile equipment its customers
need and expect.
With more than 25 years in the business, Kelly is an
award winning manufacturer, proudly at the
forefront of chain harrow innovation at its inception
and continuing to lead the way.
Why choose the Kelly Diamond Harrow?
A robust, versatile machine, requiring very little servicing and maintenance will keep on working day
after day, year after year. Originally designed to mulch and incorporate stubble, it has become the
multi use implement on the farm.
The machine is designed and built to withstand the harshest of conditions while the range of ground
engaging tools gives you a choice of the right tool for the right job.
• Versatile and often described as the “most useful tool on the farm”
• Simple operation and set up
• No manual input required during operation
• Minimal maintenance and servicing required, leaving more time in the field
• Reliable and strong framework that has been rigorously field tested
• High productivity. Work rate efficiency is high
• Light draught and also relatively easy to pull, thereby saving on fuel costs
• Ability to cover large areas in a short time, saving time and labor.
Kelly continually uses and tests their own machines to ensure they are efficient, strong, reliable,
easy to use and easy to service.
A better seedbed for a better bottom line
Integrated weed management reduces the reliance on chemical controls and is a key to managing
herbicide resistance in weeds, thereby saving a herbicide application and the associated cost.
• Smoothes and levels soil perfectly for better planter performance and accuracy
• Ability to remove deep wheel ruts and marks in as little as one pass
• Accelerates stubble breakdown
• Creates a rich mulch layer which helps to retain sub soil moisture; a must for the American farmer
• Chemical free weed control
• Improves seed to soil contact for better germination
• Major savings on chemicals for weed control.
The biggest benefit of all these tasks is that you are left with loose friable soil to sow into on top of
a firm stable seedbed, which in turn provides a better bottom line.
Best tillage implement
The Kelly Diamond is by far the best tillage implement we have ever
purchased. We sold our turbo till and bought the Kelly. It was perfect for
what we wanted to do on our farm. Easy to maintain and no disc axles.

45 rice crops of experience
I’ve just grown my 45th rice crop and in all those years this is THE best
tool that has ever been on this farm.

A better seedbed for a better
It does about the prettiest job of making a seedbed you’ll ever see.
It’s the first truly revolutionary tillage tool I’ve seen in a long time.
Gary and Steven Ewert, Liberty, MO.
Wet soil is no problem
This tool works better in wet soil than any other tool we have.

Best thing since sliced bread!
My sons and I purchased one of your Kelly 45’ Harrows last spring.
Whoever dreamed up this implement needs to be awarded some kind of
Nobel prize! It is the best thing since sliced bread.
We have pulled the machine over about 6000 acres without a single
breakdown. It has saved an unimagineable amount of time, fuel and

Disc Chains for all situations
A concave replaceable disc mounted in a heavy cast steel boss with a hook and eye to link
together. The sharp disc provides penetration into the toughest of soils while the weight and shape
of the boss keep the disc cutting and control the working depth. Heavy residue management and
reliable weed control make this new disc our flagship product. Weight 75lb/ft - 112kg/m, Spacing 8”.
The most versatile of the Kelly Disc Chains, the CL1 is a concave disc made from hardwearing cast
steel alloy with a hook and eye for linking together. The ideal tool for stubble management, weed
control, leveling soil and while working at just the right depth creates the perfect seedbed.
Can be used in combination with other chains to give the best fit for your conditions.
Weight 47lb/ft - 70kg/m, Spacing 7”.
W36 Disc Chain W36/25/7
A lightly curved disc made from wear resistant steel welded to a heavy chain that is ideal for mulching
stubble and leveling soil. Weight 36lb/ft - 55kg/m, spacing 7”.
Spike Disc Chain SD49/27/5
10 spikes per disc and 5 inch spacings give this heavy duty spiked disc chain real effectiveness.
At 49lb/ft - 75kg/m the close spaced spikes can be fitted either trailing or leading. In the trailing
direction the leveling and incorporating action combine to provide a shallow running, self cleaning
seedbed preparation tool. Remarkably effective at removing weeds this makes an ideal pre or post
seeding tool for herbicide incorporation. In the more aggressive “leading” orientation, the Spiked
Disc Chain works as a “first pass” light tillage tool, leveling and preparing a seedbed.

Servicing made easy
Keeping you working
To provide excellent service life, high quality
and reliable specialized parts have been fitted,
like extended gland cylinders, unique multi
element hub seals or precision swivel units.
In the rare event that a part needs replacing,
Kelly has also designed the components to be
easily sourced locally, in order to keep
downtimes to a minimum, so you don’t lose
time in the field.
Kelly Engineering guarantees its products against faulty workmanship
and materials. Disc Chain, Prickle Chain and Swivel units are considered
to be wear items and it’s reasonable to expect that these parts may
need to be replaced over time. We do however guarantee the Swivel
units for a period of 12 months or 10,000 acres, whichever occurs first.
Furthermore, provided that normal maintenance and adjustments
as scheduled (refer to the operators manual), Kelly Engineering
guarantees the useful working life of the Disc and Prickle Chains
to be in excess of 5 years or 50,000 acres, whichever occurs first.
