The serial number is located on the data plate mounted on the front of the machine.
Older machines will have the number stamped into the joining plates on the left hand side where the main pull joins to the center frame or on the main hydraulic cylinder mount plate on the center frame
Refer to the troubleshooting section in the hydraulic chapter of the operator’s manual.
The swivels are serviceable – please see the https://kellytillage.com/wp-content/uploads/2022/04/Swivel-Rebuild-Instructions-1.pdf
We can refurbish cylinders using genuine seals and components. Most competent dealer workshops can service cylinders and indeed many farm workshops have the capability to perform the task.
The disc chains are designed to work with the concave side of the disc facing forwards. Spiked Disc Chain is intended to run with the convex side of the disc forwards so that it is less aggressive.
This is dependent on disc type and soil type more than machine size.
Technically yes. Most diamond harrows however are designed for prickle chain and may suffer stress from the extra load imparted by the Kelly Disc chains. The Kelly Diamond Harrow has been designed and guaranteed specifically for the range of Kelly disc chains.
We recommend a rebuild kit that includes a replacement shaft, seal and bearings when refurbishing your swivel bearing units. These kits are available as spare parts from your dealer. Spare parts manuals are available for download here.
You can find the bearing number in the spare parts manual. We use metric, deep groove ball bearings. Use only high quality bearings, as inferior types will fail prematurely when put back in service.
No, that isn’t necessary. The tail lift is advantageous when turning very short as it avoids dragging a furrow as you turn It is quite okay to turn with the whole machine in working position. In heavy residue it may be necessary to raise the tail to avoid blockage when turning short. It can be useful to raise the front also but not necessary.
The swivel height at the front of the rear gang of discs is too low. The leading disc is digging too much and must be adjusted upward by moving the spacers on the drop leg to be above the frame. See operator’s manual for adjustment.
The discs at the very front of your machine are too low and working too aggressively. Set the main pull level with the ground and insert depth stops on the tongue cylinder. Raise the front swivels by shortening the height adjusting chains. See operator’s manual for details.
The leading edge of the short module chain is too low and digging aggressively. Raise the leading disc by shortening the height adjusting chain. See operator’s manual .
The front is too low. Although this may sound unusual, this creates a mound in the centre line. The module chains work through this and the tail chains clear the soil away, leaving the original unworked strip exposed. Raise the front to allow the modules to work effectively. Raise the tail to just cover the wheel mark left from the castor wheels.
Yes. The left and right movement for soil from the two gangs of discs does an excellent job of filling ruts and levelling the soil.
The discs in most cases are quite blunt and are intended to bruise and split the stubble.
Loose dirt is mixed with the residue, introducing microbes into the broken stubble and providing an ideal environment for decomposition.
The disc chains accelerate decomposition rather than cutting the stubble.
This is extremely efficient and makes best use of the time between harvest and planting and allowing the most efficient application of time and energy to get the job done.
At speeds higher than the optimum for the conditions you will experience:
Poor performance as the discs loop or skim over the ground Machine bounce. will leave a corrugation on the surface that will diminish planter performance and operator comfort in operations following the disc chain. As soon as corrugations are detected behind the machine a new, slower operating speed must be adopted. Slow down.
You should consider replacing your KELLY Disc Chains when they are no longer performing the desired outcome they were originally purchased for. KELLY Disc Chains are considered to be wear items and it’s reasonable to expect that these parts may need to be replaced over time.
We would recommend replacing K4, CL1 and W36 Disc Chains when they are worn to the bottom of the KELLY logo or 4.9 inches (125mm) from the center of the discs. For CL2 Disc Chains we would recommend replacing when they are worn to 5.5 inches (140mm) from the center of the discs, as indicated by the linked document.
