(23) Adequate front-end weight is required to maintain good front-wheel-to-ground contact for steering control and tractor stability. Refer to your tractor manual and the Specifications section 6.
Operation 10. On smaller compact tractors, front-end weights or front-wheel ballast may be necessary to ensure full tractor stability and prevent backward tractor turnover. 11. To demount the machine, find a level hardstanding area and carry out the above procedure in reverse. TINE SELECTION Your aerator is available with a wide selection of tines and tine heads. Choose your tine type size and spacings required, then change the tine head accordingly.
Operation FIELD OPERATION WARNING Clear the area to be aerated of all bystanders. No-one should be within 20 meters of this machine or tractor. TURF HOLDER ADJUSTMENT Before starting your new aerator, remove the rear castor stand. Lower the machine on the 3-point linkage until the depth control roller is resting on the ground. From the rear of the machine, check that the tines line up exactly with the center of the gap in the “Turf Holder” fingers. Adjust the turf holders if necessary.
Operating NOTE: Remember when depth changes are made, you will need to adjust your top link length to give the correct machine angle. 4. Re-tighten the locking off handles before running the machine, even if you are just testing for correct depth. OPERATING When first operating the machine, you may wish to try your first run on a practice area to allow the operator to become familiar with the operation. WARNING Clear the area of all bystanders.
Maintenance Proper servicing and adjustment is the key to the long life of any machine. With careful and systematic inspection you can avoid costly repairs and time. DRIVE BELTS GENERAL 1. To transmit the power to the crankshaft pulley. After using your aerator for four hours, check all bolts and fasteners are tight. 2. To provide drive line protection by slippage when the machine is overloaded by dry ground conditions or sub-surface stones are encountered.
Maintenance 2. Pull the end of the link over the tab (Fig. 17). ASSEMBLY 1. Hold the belt with tabs pointing outward Fig. 17 3. Rotate belt end with tab 90 degrees Fig. 20 2.
