Spike Tooth Replacement
Always secure the harrow in the UP position with solid supports before servicing the underside of the
harrow. Never work under equipment supported by hydraulics. Hydraulics can drop equipment if
controls are activated or if hydraulic lines burst. Either situation can drop the harrow instantly, even
when the power to hydraulics is shut off.
NOTE: Always replace spike teeth and locknuts at the same time to ensure that the locknuts will not
loosen, allowing the spike teeth to fall off.
Always inspect the spike teeth before each use. Make certain they are properly installed and in good
working condition. Replace any teeth that are lost, worn excessively, or broken. Place the tractor gear
selector in park, set the brakes, shut engine off, and remove the ignition key. To replace the teeth:
1. Secure the harrow in the UP position with solid supports before servicing the underside of the
harrow.
2. Remove the 1/2"-13 locknut (#2) and spike tooth (#3) from the harrow bar (#1).
3. Insert the new spike tooth (#3) in the harrow bar (#1) and secure it with a 1/2"-13 new locknut
(#2). Tighten the locknut to the correct torque.
Storage
When you are ready to park or store your harrow, it is best to park it on a dry, hard packed gravel or
concrete surface where it remains visible and grass and weeds cannot grow up through it. A harrow
setting in deep grass and weeds can be hard to locate and hazardous to vehicles, livestock, and
people not seeing the harrow covered in vegetation. Clean, inspect, service, and make necessary
repairs to the harrow when parking it for long periods, and when parking it at the end of a working
season. This will help ensure the harrow is ready for field use the next time you hook up to it.
Always secure the harrow in the UP position with solid supports before servicing the underside of the
harrow. Never work under equipment supported by hydraulics. Hydraulics can drop equipment if
controls are activated or if hydraulic lines burst. Either situation can drop the harrow instantly, even
