Tine Shear Bolts
• The DR ROTO-HOG Premier Power Tiller drive components are protected from damage by Grade 5 Shear Bolts in the Tine
Assemblies. The Shear Bolts hold the Tine Assemblies in proper location on the Drive Axles. Should a Tine Assembly strike or
pick up a large hidden object and jam, the Shear Bolt holding the Tine Assembly to the drive shaft will shear or break, protecting
the drive components of the DR ROTO-HOG Premier Power Tiller from major damage.
• Two (2) extra sets of Tine Shear Bolts with Lock Washers are included with the DR ROTO-HOG Premier Power Tiller. They are
located in the Tiller Stake Support Bracket on the rear of the Tiller.
•
The design of the Tine Shear Bolt is to loosely fit when properly installed.
When performing any maintenance, you must first shut off the Engine; wait five (5) minutes to allow parts to cool and disconnect
the Spark Plug Wire, keeping it away from the Spark Plug.
NEVER attempt to use a Bolt or Pin that is larger or harder than the original Grade 5 Shear Bolts.
