Part of the New Holland Operator Manuals.
A warning lamp comes on mid-field and nothing on the tractor tells you which circuit it belongs to. That is the gap this 122-page New Holland 6610S operator manual PDF closes: factory publication 86579555, written for all four tractors in the 10S Series. Universal symbol pages decode every gauge and rocker switch; operation covers P.T.O. hookup, top link sensing draft control, remote valves for double-acting cylinders, and rear wheel track adjustment. Lubrication and maintenance runs nearly a third of the book, from the service interval chart and grease fitting locations to dry and oil bath air cleaner servicing. Set clutch pedal free play between 1.1 and 1.6 in. (28 to 41 mm); a four-cylinder sump takes 11.4 litres, the 7810S 20.9. Most of this you face alone, nobody in the yard to ask. Bookmarked and searchable, and it prints clean, so the pages can live on the bench and take their share of grease before the weather turns.

New Holland 5610S, 6610S, 7610S, 7810S Common Problems This Manual Covers
New Holland 7610S cranks but will not start after sitting, rough cold-start with white smoke
Drain the sediment bowl and check for water or cloudy fuel before you touch anything else. Bleed the fuel filter and injection system following the procedure starting on page 69, working the primer until clean fuel runs with no bubbles. In cold weather use the thermostart procedure on page 27 rather than extended cranking.
Manual Section: Bleeding Fuel System p. 69No crank, no dash lights, or starter clicks intermittently when key is turned
Clean both battery posts and cable ends until bright, then verify the battery holds 12v and meets the 107 a/h at 20 hours rating listed on page 105. Inspect the harness behind and under the hood for chafed insulation where it passes the hinge. If you jump start, use a 15 amp rated extension lead as noted on page 29.
Manual Section: Specifications p. 105Clutch slips pulling a loaded wagon uphill, pedal feels soft with no free play
Measure pedal free play at the pad before the next field pass. Page 69 calls for 1.1 to 1.6 in. (28 to 41 mm) of travel before the pedal meets resistance. Adjust the pull rod to bring it back into range, then road test under draft. If free play will not hold, book the shop visit now, not at harvest.
Manual Section: Controls, Instruments and Operation p. 69Hydraulic oil weeping at loader hose fittings only when the lever is operated
Lower the loader, shut down, and relieve pressure at the remote couplers before handling anything. Wipe each fitting dry, then cycle the cab loader valve and watch for the first bead of oil to pinpoint the leaking connection. Retighten or replace the fitting, then bleed trapped air from the remote cylinders using the procedure on page 46.
Manual Section: Bleeding Remote Cylinders p. 46Temperature gauge climbing into the red during heavy PTO work on hot days
Shut down and let the engine cool before opening the radiator cap. Clear chaff and crop trash from the radiator screen and grille, then check coolant level: a 4-cylinder system holds 14.5 litres per page 90. Check fan belt tension using the adjustment on page 78. On turbocharged models, idle three to five minutes before shutdown.
Manual Section: Lubrication and Maintenance p. 90Wheel nuts found loose after changing rear wheel spacing for row work
Retorque every nut before the tractor goes back in the field, then again after the first hour of operation. Front disc to hub nuts call for 133 Nm on two-wheel drive and 475 Nm on four-wheel drive per page 70. Work a crisscross pattern, and recheck daily until the readings stop moving.
Manual Section: Specifications p. 70Frequently Asked Questions
Where are the torque specifications for the wheel nuts on the New Holland 5610S, 6610S, 7610S, and 7810S tractors?
Torque specifications for wheel nuts vary by component and tractor configuration. For example, front disc to hub nuts on a two-wheel drive model require 98 lbf. ft. (133 Nm), while rear disc to hub nuts on manual adjust wheels require 288 lbf. ft. (390 Nm). p. 70
What are the fuel filter replacement specs for a New Holland 5610S, 6610S, 7610S, 7810S tractor?
The fuel filter should be replaced as part of the 300-hour service. When installing a new filter, smear clean engine oil around the rubber seal, screw it on until the faces just meet, and then tighten a further 3/4 of a turn. p. 76
What is the correct valve clearance for a New Holland 5610S, 6610S, 7610S or 7810S tractor engine?
The correct valve clearance for all models is 0.014 - 0.018 in. (0.36 - 0.46 mm) for the intake valves and 0.017 - 0.021 in. (0.43 - 0.53 mm) for the exhaust valves. p. 83
What is the engine oil capacity for a 4-cylinder engine including the filter?
The engine oil capacity for a 4-cylinder engine, including the filter, is 20.1 Imp. pints, 24.1 U.S. pints, or 11.4 litres. p. 76
How do I adjust the fan/alternator belt tension?
Tension is correct when the belt can be deflected by 0.50 - 0.75 in. (13 - 19 mm) in the center of the run. To adjust, loosen the upper and lower mounting bolts and move the alternator. p. 78
