SAME Deutz-fahr AGROLUX F 50, AGROLUX F 60, AGROLUX F 70, AGROLUX F 80 Workshop Manual

You are pulling a transmission on an AGROLUX F 70 because the HML unit lost drive. The aftermarket PDF you obtained says “tighten to spec” but gives no actual number. That is not a manual. That is a fire starter. This is a 398-page OEM workshop manual from SAME Deutz-fahr covering the AGROLUX F 50, AGROLUX F 60, AGROLUX F 70, and AGROLUX F 80. It comes straight from the factory that built the tractor. It lists every torque value, every sealant type, every hydraulic diagram. If you are rebuilding a gearbox or chasing a hydraulic leak, this is the only document you should trust.

Section 10 alone runs over 100 pages on the transmission, rear PTO, front axle, and hydraulic system. I have torqued enough head bolts to know that 20 ft-lb difference between a bolt and a stud will cost you a housing. The factory standard tightening torques are laid out in the first few pages – nuts, bolts, fittings, plugs, 37-degree flare fittings, and pipe eye attachments. There is a whole page on threadlockers, adhesives, sealants, and lubricants. If you use Loctite 242 where the manual calls for 271, you will be drilling out bolts later. That is your time. Don’t waste it.

Transmission and HML Assembly – What the Manual Covers

Gearbox and shuttle assembly gets its own subsection for versions with and without HML. You get the full break down: housing, HML assembly, control rods for shuttle and underdrive, range and parking brake assembly, four-wheel drive engagement, differential assembly, brakes, and rear axle. Every removal and refitting procedure is there. The manual even includes a section on checking the reduction unit end float for the HML unit – something the aftermarket copies copy incorrectly. If you are separating the engine from the transmission, the preparation steps are in Section 30. Lift points, what to disconnect first, what to label. This is not a guessing game.

Hydraulic System – 12 Subsections of Factory Diagrams

Four hydraulic diagrams are included: standard version in two parts, full optional version in two parts. Steering circuit gear pump, lift circuit gear pump, power steering, HML solenoid valve assembly, auxiliary services control valve, trailer braking valve, services solenoid valve assembly, lift control valve. The hydraulic lift (mechanical version) removal and refitting is covered in its own subsection. Need the charge pressure? Page 73 shows the lift control valve disassembly and assembly. Every o-ring size, every torque for the valve body bolts. If you bypass the factory diagram and guess the port routing, you will get air in the system and waste half a day bleeding it. I have seen it happen.

Section 30 – Body, Engine, Clutch, and PTO Rebuild

Engine hoods, wheels (front and rear), safety roll bar, fuel tank, front support, platform, 4WD shaft, engine separation, clutch assembly (including checking clutch plate wear and renewing the release bearing), starter motor, HML unit complete removal and disassembly, gearbox and shuttle assembly removal and refitting, gear selector rods, four-wheel drive engagement control, hydraulic pumps for steering and lift circuits, trailer braking valve. Each procedure has a removal step and a refitting step. The manual does not assume you know which bolts come out first. It tells you.

Who Needs This Manual and Why

If you own an AGROLUX F 50, F 60, F 70, or F 80 and do your own repairs, this manual keeps you from turning a $30 seal replacement into a $2,000 split. I have seen farmers use a crowbar to separate a housing because they did not know the hidden bolt behind the PTO shield. The manual shows you the shield removal in the safety roll bar section. For shop owners, this eliminates the “I think it’s this torque” excuse from junior techs. You hand them the page. They do it right. For DIYers who have never split a tractor, the lifting instructions and safety precautions are worth the price by themselves. The manual warns against makeshift tools and explains why you use the special tool for the HML solenoid valve assembly. Ignore that warning once and you are replacing a valve body.

Source Authenticity – OEM vs. Aftermarket Documentation

This is the original factory workshop manual, not a scan of a scan or a reprint from a third party. The document title reads “SAMEDEUTZ-FAHR_AGROLUX_F_50-AGROLUX_F_60-AGROLUX_F_70_Workshop_Manual_en-23728002047.pdf” and the copyright is SAME DEUTZ-FAHR DEUTSCHLAND GmbH. The introduction explicitly states that the manual is reserved to Authorised Dealers and Service Centres and that any reproduction is forbidden without written permission. That is how you know the data is right. Aftermarket manuals often round torque values to the nearest 5 Nm, which on a hydraulic fitting means a leak. This one gives standard tightening torques for nuts, bolts, fittings, plugs, 37-degree fittings, and pipe eye attachments. The conversion factors table lets you switch between metric and imperial if your torque wrench is in ft-lb.

Frequently Asked Questions

Does this manual cover the front axle on the AGROLUX F 80?

Yes. Section 10, subsection 3 covers the front axle – final drive, pinion, differential, and differential lock. Removal and refitting procedures are included.

What torque values are listed for the hydraulic lift control valve?

The standard tightening torques section covers bolts, fittings, and plugs. The lift control valve removal/refitting subsection references those tables. No made-up numbers.

Is this the same manual used by SAME Deutz-fahr dealerships?

The introduction states the manual is reserved to Authorised Dealers and Service Centres. It is the exact same document the factory sends to dealers. The hydraulic diagrams, torque charts, and disassembly procedures are identical to what a dealership tech would use.

Can I use this manual for a manual transmission rebuild on an AGROLUX F 60?

Yes. The gearbox and shuttle assembly section covers both versions – with and without HML, including the 5-speed variant. Control rods, primary shaft, secondary shaft, and gear selector rod disassembly/assembly are all there. The Manual Transmission information is factory-sourced and includes all shim tolerances.

If you are serious about keeping this tractor running without guesswork, access the Factory Manual. It is 398 pages of OEM data – no aftermarket approximations, no skipped steps, no missing torque values. Your AGROLUX F 50, F 60, F 70, or F 80 deserves the same documentation the factory techs use. Get it, print the pages you need, and keep them in the shop with the grease stains.
