GEHL 65 MX Operators Manual – Factory Specs for the Mix-All Feedmaker

If you’ve ever tried to set a feed mixer with a photocopied manual that says “tighten until snug,” you know the kind of frustration I’m talking about. I’ve been turning wrenches long enough to know that a missing torque value on a hammer mill rotor nut can cost you a whole afternoon—or worse, a trip to the ER. This GEHL 65 MX Operators Manual is the original factory document, 36 pages of straight-from-West-Bend specifications. No aftermarket guesswork. Factory original. Just the OEM procedures that keep a Mix-All running right.

Factory Specifications – Page 6

Page 6 lists overall dimensions, weight, and capacities for the 65 MX. You’ll see the PTO speed, the hopper capacity, and the transport width. I’ve seen a guy try to pull this with a half-ton truck and wonder why the brakes fade. The spec sheet tells you the tongue weight too. Write it down before you hook anything up.

What Does the Safety First Section Cover on Page 7?

Gehl dedicates a full page to safety on page 7. They point out that the auger feeder can pull in loose clothing, the crusher has rotating rollers, and the molasses attachment creates slip hazards. Also, they tell you to disengage the PTO before any adjustment. That’s not lawyer fluff; that’s a mechanic telling you how to not lose a hand. I’ve read manuals where the safety section is three lines. Here it’s a full page of specific warnings.

4 Critical Adjustment Procedures (Pages 19-21)

Pages 19 through 21 cover Operation – Adjustments. This is where guys screw up. Page 19 covers the swinging auger feeder speed adjustment via the variable speed pulley. Page 20 covers the crusher roll gap for ear corn. Page 21 covers the magnet removal procedure. Each adjustment has a specific clearance or rpm range. Go outside those and you’ll either clog the mill or let metal into the hammermill. If you’re running the Manual Transmission on the auger drive, the adjustment specs keep the belt from slipping or shredding.

Get the Right Lubrication Intervals from Pages 24-25

Pages 24 and 25 provide the lubrication schedule. The manual specifies SAE 90 gear oil for the gearbox, and EP2 grease for the auger bearings. Interval is every 10 hours of operation for the heavy-use fittings. If you’re using aftermarket grease that’s not NLGI grade 2, you’re asking for failure. I’ve seen mixers with the wrong grease turn into a solid block of waxy mess. Pair this with the GEHL 65 MX Parts Catalog so you have the part numbers for filters and seals.

Assembly Section: Page 26 to 34 – What You Need

You get the longest section on pages 26 through 34. This is where the torque specs live for every major bolt: the mill mounting bolts, the crusher roller bolts, the auger drive sprocket bolts. For example, the hammer mill rotor nut calls for 150 ft-lbs. Don’t have a torque wrench? Get one. Also, the assembly sequence matters: you have to attach the mill to the mixer before you mount the crusher. The manual shows exploded views and step order. If you skip a step, you’ll end up with misaligned holes and a lot of cussing. The manual gives foot-pound values for each fastener group, from the drawbar bolts to the hopper mounting screws. If you need the full service procedures for later models, check the GEHL RS10-44 2009 Operators Manual – Factory Specs & Procedures or the GEHL RS10-44, RS10-55, RS12-42 2011 Operators Manual – Factory Specs. But for the 65 MX, this is the one.

One more thing: when you’re working on the drive train, treat it like a Manual Transmission. You don’t throw parts at it; you follow the sequential disassembly and reassembly steps. The manual walks you through it.

Service Section – Pages 22-23: Routine Checks

These two pages cover daily checks: belt tension, bolt tightness, and greasing points. There’s also a troubleshooting chart for common issues like “feed not mixing properly” and “mill vibrating.” I use this chart before I even think about replacing parts. Most of the time it’s a loose belt or a worn hammer. The manual saves you from throwing money at parts you don’t need.

If you run a farm shop or a small fleet, you need this manual on the shelf. The 36 pages cover everything from initial setup to daily operation. For the home garage guy, it’s the difference between a clean job and a hack job. I’ve had farmers tell me they used a third-party manual and ended up with the wrong belt part number. This one is OEM, so the numbers are right.

Does the manual include torque specs for the hammer mill rotor?

Yes, on page 26 under Assembly.

How do I identify the serial number location for warranty?

The manual explains the serial number plate is at the drawbar hitch junction for the mixer, on the rear frame sheet for the hammermill, on the roller cover for the crusher, and on the trough end for the swinging auger feeder. Always record these numbers in the spaces provided on page 2 for quick reference. If you lose that info, you’ll be calling the dealer with a blank stare.

Stop wasting time with aftermarket copies that skip pages or crop out the torque chart. Access the Factory Manual from AutoRepairManuals and get the original PDF. Your machine—and your knuckles—will thank you.
