Pre-delivery checks, tractor hookup, mill and blower operation, feeder adjustments, lubrication, transport and storage: Form No. 907585, the 92-page Gehl 125 Mix-all grinder mixer operator manual, walks through each one. Troubleshooting in this Gehl Mix-all operator manual PDF fills a solid share of the book, with charts split by mill and mixer drive, mill, mixing and hydraulics, so the symptom you see points to a likely cause and fix. Controls, guards and shields get their own illustrated section, and the inside back cover holds standard hardware torque values for Grade 2, 5 and 8 bolts plus metric 8.8. Run the tractor at rated PTO speed for a 2700 RPM mill cylinder, and swap the hydraulic oil filter every 100 hours of operation. A plugged mill on a loaded tank eats the afternoon. Bookmarked and text-searchable, this PDF is yours after one purchase, kept for as long as your 125 keeps grinding.
