Agroplus 60, 70, 80 Workshop Manual

If you’ve been chasing a clutch issue on an Agroplus 60, 70, or 80 and found yourself guessing at end float or hydraulic pressures, you’re not alone. I’ve seen too many tractors come into my shop with stripped bolts from aftermarket manuals that skip the factory sequence. This Agroplus 60, 70, 80 Workshop Manual is the real deal – OEM factory documentation, 509 pages, covering everything from the engine block to the Powershift unit. No condensed reprints, no third-party rewrites.

Agroplus 60, 70, 80 Workshop Manual: Factory OEM Specs

Page one of this manual spells it out: it’s written for the trained technician who has attended factory service school. That’s the level of detail you’re getting. The TOC on page 2 lays out sections for engine, clutch, transmission, drive axles – each with sub-sections for specific models. For example, the clutch section lists separate units for the 60, 70, and 80, plus a specific USA 6-blade unit. You won’t find that level of precision in a generic manual.

Engine and Transmission Coverage

The Engine chapter (starting page 11 in the book) runs through complete overhaul procedures. But the real meat is in the transmission section. Gearbox specifications include ratios for the 5-speed x 2 range with mini-reduction (20 FWD + 10 REV) and the 3-range Super-reduction plus Powershift (45 FWD + 45 REV). Each ratio set is documented for the 60, 70, and 80 horsepower variants. Understanding the principles of a Manual Transmission helps when you’re working through these gear trains, but this manual gives you the exact tooth counts and backlash specs – no guesswork.

Does This Manual Cover the Clutch and Powershift?

It does, in depth. The clutch section includes bleeding the hydraulic circuit, stripping the slave and master cylinders, and adjusting the control pedal. For the Powershift unit, you get hydraulic circuit diagrams, procedures for detaching the unit from the gearbox, and the critical adjustment of end float. The 5-speed x 2 range transmission with mini-reduction is a complex layout – refer to the Manual Transmission page for fundamentals if you need a refresher, but for the actual work, stick to this manual.

509 Pages of Teardown and Inspection Data

That’s 509 pages of factory-authorized procedures. Not a reprint, not a scan of a scan. The manual walks you through removing the gearbox, disassembling the inversor control rods, examining shafts, gears, synchronizers, and adjusting play using thrust plates. Each step includes warnings about assembly of the P.T.O. unit and range reduction gears. The conversion table on page 9 lets you translate metric torque values to imperial foot-pounds. You need that table because the original specs are metric – but at least you have the actual numbers.

Get the Right Torque Specs from the Conversion Table

Torque values are scattered through the transmission chapter – tightening torques for the gearbox, bevel drive adjustment, and P.T.O. clutch pressures. Without the conversion table, you’re guessing. This manual gives you the raw data. If you also need part numbers for ordering, the separate Agroplus 80 Parts Catalog – 276 Page Factory Parts Breakdown is a smart companion.

Skip that step and you will pay.

FAQ – Common Questions About This Manual

Does this manual cover the Agroplus 60 model separately?

Yes, the manual includes specific sections for the 60, 70, and 80 models, including clutch units and gear ratios.

Are torque values listed in imperial units?

The manual comes with a conversion table on page 9 so you can convert metric to imperial. But the factory specs are originally metric – you need to do the math.

What about the Powershift unit hydraulic pressures?

The manual includes the procedure for checking the H-M-L control unit inlet pressure, along with hydraulic diagrams. It also covers adjustment of end float in the Powershift unit. This is a critical step that many generic manuals skip entirely. If you don’t get the end float right, you’ll be pulling the transmission again inside a hundred hours. The manual also details the pressure control valves assembly and the full hydraulic control circuit – data you won’t find in aftermarket documentation.

Can I use this manual for the Agroplus 80?

Yes, the Agroplus 80 is covered in the same volume.

Other manuals in the same family include the Massey-Harris-Ferguson TEF20 1956 Workshop Manual – OEM Specs for vintage tractors, and the IKA Renault Tornado Engine Workshop Manual – OEM Specs for engine-specific rebuilds. If you want the real factory data, access the Factory Manual and keep it on the bench.
