INTRODUCTION:

When ordering service parts, specify the correct part number, full description, quantity required, the unit model number and serial number. For your safety and continued proper operation, use only genuine GEHL service parts. The model and serial number for this unit are on a tag located on a panel on the front of the cab.

• ”Right” and ”left” are determined from a position sitting on the seat and facing forward.

• Refer to the abbreviations table located on this page for the various fastener descriptions. Standard attaching hardware torque values are also provided on the inside back cover. Metric torque values shown in the illustrations are in Newtonmeters and can be converted to foot-pounds by multiplying by 0.738.
