GEHL 5205, 5305, 5380 Installation Manual – Factory Setup Instructions

I have seen too many dealer setups go sideways because somebody thinks they can wing it on a 3-auger mixer feeder. You get one shot at the oil bath, the planetary gearbox level, and the PTO alignment before you start chewing up bearings. That is why you need the GEHL 5205, 5305, 5380 Installation Manual – not a photocopy, not a third-party rewrite – the original 16-page dealer setup instructions straight from the factory. Every plug location, every cap screw pattern, every drawbar dimension came off the same line the machine was built on.

GEHL 5205, 5305, 5380 Installation Manual – What This Covers

This is the printed version of the GEHL dealer setup packet for the 5000 Series 3-auger Mixer Feeders. The manual walks you through unpacking and assembly starting on page 1, with separate procedures for trailer and stationary models. You get the exact sequence for installing the front drive compartment plug, filling with SAE 30W motor oil, checking planetary gearbox sight gauge, mounting the PTO shaft with locking pin, and securing the safety chain to the trailer tongue. The final pages lay out the drawbar pin hole centerline – 15-1/2 inches from the PTO shaft groove – and reference the ASAE standard S365 for weight limits when towing without brakes. All three models – 5205, 5305, and 5380 – are covered on the same pages because the frame and driveline differences are called out where they matter.

Trailer Setup Procedure: Oil Capacities and Plug Locations

Page 1 gives you the front drive compartment oil capacity: 6 gallons U.S. for the 5205, 10 gallons U.S. for the 5305 and 5380. That is not a ballpark number – that is the mark you need to hit so the chain in the lower drive sprocket gets covered. You also get the exact threaded hole for the plug on the underside of the front drive compartment, and the sealant requirement. Skip sealing that plug and you will be chasing oil drips later.

Check the Planetary Gearbox Oil Level Correctly

The sight gauge on the left side of the gearbox is your only reliable indicator. This manual tells you to check it after you have topped off the front drive compartment, because the gearbox gets its supply from that same circuit on some configurations. Do not trust the dipstick if there is one – the gauge is the factory spec. If you are looking for the part number for the sight gauge, grab the GEHL 5205 5305 5380 Parts Catalog alongside this manual.

PTO Shaft Installation: Locking Pin and Safety Chain

The procedure on page 2 covers pushing in the locking pin and sliding the PTO shaft onto the planetary gearbox. Then you hook the PTO safety chain onto the trailer tongue. That chain is not optional – it keeps the shaft from dropping if the pin fails. The manual also tells you to check for foreign objects in the mixing chamber and discharge chute before you close anything up. I have pulled wrenches out of those chambers – follow it. The PTO alignment depends on your tractor’s Manual Transmission drawbar height, which the manual addresses on page 3.

3 Models Covered: 5205, 5305, and 5380

One manual, three models. The differences are mostly in oil capacities and frame length, not in the core setup steps. If you are working on a 5380, the plug locations and torque patterns are identical to the 5305, but the front drive compartment holds the larger 10-gallon fill. The manual calls attention to those differences in bold type so you do not overfill a 5205. Pair this with the GEHL 8435 8500 Installation Manual – Factory Specs if you have the larger frame in the shop.

Drawbar Adjustment and Towing Safety

Page 3 of this manual has the number you cannot ignore: 15-1/2 inches from the tractor PTO shaft groove to the drawbar pin hole centerline. That dimension keeps the U-joint angles within spec. Deviate and you will tear up the driveline in 50 hours. The warning section also calculates the towed weight limit: total implement plus load cannot exceed 1.5 times the weight of the towing vehicle. That is ASAE S365 – not a suggestion. For the tractor side of this, you need to understand the Manual Transmission output shaft load ratings – your dealer can supply those if your tractor manual is missing pages.

Source Authenticity: OEM vs. Aftermarket Manuals

This is the same document GEHL printed and shipped with every 5205, 5305, and 5380 mixer feeder. It is not a scan with missing margins. It is not a translation that reverses left and right. The pages are numbered 1 through 16, and the binder hole placement matches the original dealer binder. Compare that to an aftermarket PDF that cuts off the torque callouts – you will find yourself guessing on the lock washer pattern. That guess costs you a gearbox. GEHL 7285 7335 7210 7435 7500 Installation Manual – OEM Specs covers the bigger line if you need that reference.

FAQ

Does this manual cover wiring or hydraulic diagrams?

No. This is strictly a mechanical setup guide – plugs, oil levels, PTO shaft, drawbar alignment, and safety checks. For hydraulics, you need the separate operator’s manual.

Can I use the 5205 instructions for a 5380?

Yes. The 5205, 5305, and 5380 share the same assembly sequence. The only differences are oil capacities (6 gallons for 5205, 10 for 5305/5380) and frame length. The manual calls out both on page 1.

You are not going to find a better reference for setting up a 5000 Series mixer feeder than the factory dealer packet. The oil capacities, the plug locations, the PTO shaft locking pin procedure – all of it is laid out the way GEHL intended. Access the Factory Manual and have it on the bench before you pull the crate open.
