Introduction

Row Marker OEM-290-257 

will help you lay out your garden with speed, accuracy and convenience — without the bother of

stakes, strings, tape measures and other tools. It’s fast and easy to assemble, mount and use with your TROY-BILT HORSE Model,
ECONO-HORSE, PONY or JUNIOR Model tiller too! Just follow these assembly & use instructions.

NOTE:

If you ordered a Hiller-Furrower with your Row Marker, be sure to install the Furrower blade first, as the Row Marker

attaches directly to the Furrower blade and must be used with it. Separate assembly instructions are included with the Hiller-
Furrower. If you already had a Hiller-Furrower, just attach the Furrower blade to your TROY-BILT Tiller as always and follow the
Row Marker instructions here.
