Shimming the range gear input shaft on a Powershuttle transmission is where most farm-shop rebuilds stall, and the Deutz-fahr Agroplus 85 service manual PDF carries that job to the last circlip across 370 pages written for four variants in the Agroplus tractor line. Wiring diagrams trace the electrohydraulic circuits behind front and rear PTO clutch engagement, differential lock and four wheel drive, while hydraulic schematics map the load sensing power-lift and the orbital steering unit. Resident diagnostics and All Round Tester procedures let you read fault codes off the electronic lift, and the transmission chapter, the longest in the book, ends with tightening torque tables. Set crownwheel to pinion backlash at 0.18 to 0.24 mm, and scrap any clutch disc worn below 6 mm. A guessed relief valve pressure cracks a casting. Searchable text and bookmarked chapters keep you moving until the tractor is running and back in the field.

Deutz-fahr Agroplus 75, Agroplus 85, Agroplus 95, Agroplus 100 Common Problems This Manual Covers
Deutz-fahr Agroplus 85 gears hard to engage at standstill, tractor creeps with clutch pedal fully down
Bleed air from the hydraulic clutch circuit first, then check release cylinder geometry. Set the dimension between the operating cylinder fixing face and the push rod contacting the engagement lever to 195 mm as given on page 20. Pull the disc and replace it if thickness is under 6 mm.
Manual Section: Gearshift Clutch Fault Diagnosis p. 24Three-point hitch lifts slowly or stalls under a heavy implement but raises fine empty
Warm the oil, then gauge the lift circuit at the pump outlet. Standard pump delivery is 41 l/min and the oversized pump gives 57.5 l/min per the table on page 208. Reset the relief valve to 180+10 bar. Measure the ram piston and scrap it below 109.900 mm on 75 and 85 models.
Manual Section: Hydraulic System Fault DiagnosisStrong vibration and noise through the gear lever in certain gears under load
Drain the 73 litres of gearbox and rear axle oil, then inspect the bevel gear pair and shafts. Set crownwheel to pinion backlash at 0.18 to 0.24 mm and keep shuttle shaft and layshaft end float between 0.15 and 0.60 mm, both listed on page 43. Torque the bevel pinion lock nut to 440 to 480 Nm.
Manual Section: Transmission p. 43Engine feels weak and sluggish until warm, then idle speed runs abnormally high
Check the accelerator linkage before condemning the fuel system. Verify pedal travel measures 75 mm through an angle of 32 degrees as specified on page 258, and free up any binding in the throttle rod. Then confirm engine oil level against the 9 litre capacity for 75, 85 and 95 models.
Manual Section: Controls p. 258Power-lift electronic controls throw alarm codes and the hitch drops or refuses to respond
Read the resident diagnostics before touching the valve block. Codes 11 through 55 cover EPROM, sensors, solenoid valves, radar and wheel constant faults across pages 171 to 174. Verify sensor supply voltages, since code 67 flags 5V power incorrect and code 68 flags 10V power incorrect on page 191.
Manual Section: Electronic Power-Lift Resident DiagnosticsRoad speed builds only after several kilometres on cold mornings, drivetrain feels like it is dragging
Confirm the drivetrain is not fighting a partly engaged clutch. Check disc lubrication pressure at 5 bar with a maximum of 16 bar on page 25, and verify synchronizer assembly end-float sits between 0.15 and 0.60 mm. Torque the rear wheel bolts to 490 Nm before you head back to the field.
Manual Section: Powershift Unit Fault Diagnosis p. 42Frequently Asked Questions
What are the clutch kit replacement specs for a Deutz-fahr Agroplus 75, 85, 95 or 100 tractor?
For the Agroplus 75-85-95, the disc diameter is 330 mm, and for the Agroplus 100, it is 350 mm. The minimum permissible thickness for the disc is 6 mm, and the friction disc thickness is 8.5 (+0.3/-0.3) mm. p. 14
What are the clutch release cylinder replacement specs on a Deutz-fahr Agroplus 75, 85, 95, 100?
When stripping the slave cylinder, ensure the air bleeding hole is free from impurities. The master cylinder is a Benditalia 3/4" type, and the system uses AKROS MATIC oil. p. 14
What is the engine oil capacity for the Agroplus 75-85-95 and 100 models?
The engine oil capacity for the Agroplus 75-85-95HP is 9 litres, and for the 100HP model, it is 12.5 litres. These quantities do not include the filter, which requires an additional 1.5 litres. p. 10
What is the tightening torque for the engine front support securing screws on a Deutz-fahr Agroplus 75, 85, 95, 100?
The tightening torque for the engine front support securing screws is 30 kgm (294 Nm). p. 138
What is the recommended engine oil change interval for the Deutz-fahr Agroplus 75, 85, 95, 100?
The oil change interval is every 250 operating hours for lubricants with API-CC specifications, and every 500 operating hours for lubricants with API-CD, API-CE, API-CF-4, or CCMC-D4 specifications. p. 10
