Part of the New Holland Repair Manuals.
Grease gun in one hand, three-point hitch pins in the other, and the only real question is which fittings take it and how often. Across 198 pages this operator manual answers that for the Workmaster 25, along with every other interval the tractor needs.
Coverage runs from the instrument cluster, shuttle shift lever, and differential lock pedal through PTO operation, drawbar hookup, and top link adjustment, then into a Maintenance section that spans daily checks to the full service chart. A Troubleshooting section walks symptoms on the engine, clutch, brakes, steering, hydrostatic transmission, and electrical system. Specifications close it out with wheel tread settings and tire inflation pressures.
Guessing costs more than the manual does: the wrong filter, a second teardown, a hitch pin you order twice. It downloads as a PDF you can keep on the phone in the shop or the truck, which matters when the job is timed by weather, not by the workday.

New Holland Workmaster 25 Common Problems This Manual Covers
Coolant temperature climbs during long mowing
Chaff and clippings pack the radiator screen on a compact tractor faster than anything else, and the gauge shows it before the engine does. The Specifications section lists a cooling system capacity of 4.9 L and a thermostat that starts to open at 76.5 °C (170 °F), so you can separate a plugged screen from a stuck thermostat.
Manual Section: Specifications p. 181Fan belt squeal and weak charging
A loose belt shows up as a shriek on cold starts and a battery that never quite comes back up. Set fan belt deflection to 10-12 mm (0.4-0.5 in) as given in the Maintenance section before you condemn the alternator.
Manual Section: Maintenance p. 143Clutch drags going into range
Gears fight you on the range lever, or the tractor still creeps with the pedal down, when the clutch does not fully release; the Troubleshooting chart lists excessive clutch pedal free play among the causes. The Maintenance section calls for 20-30 mm of clutch pedal free play and shows where to take it up.
Manual Section: Maintenance p. 141Three-point hitch drops too fast
An implement that slams down or refuses to hold position is often the drop rate control valve rather than a tired pump. Operating Instructions covers the Hydraulic Power Lift drop rate control valve, top link adjustment, and attaching three-point hitch equipment.
Manual Section: Operating Instructions p. 75Vibration traced to loose wheel hardware
Hours on rough ground work wheel bolts loose, and the shake usually gets blamed on tires first. The Maintenance section calls for 176-196 N·m (130-145 lb ft) on both front and rear wheels, which is also the figure to use after any wheel tread change.
Manual Section: Maintenance p. 152Hydrostatic forward pedal feels soft
Loss of drive or a forward pedal that goes limp on an HST machine points at linkage, fluid level, or the transmission itself. The Troubleshooting section carries hydrostatic transmission symptoms alongside the clutch, brake, steering, and electrical charts.
Manual Section: Troubleshooting p. 173Rear remote couplers leak or bind
Quick couplers on the rear remote valve collect grit from implement hoses and start weeping or refusing to latch against residual pressure. Controls and Instruments identifies the rear remote valve female couplers as 12.7 mm (0.5 in), so you match the tips before ordering.
Manual Section: Controls and Instruments p. 71Frequently Asked Questions
Which tractor and engine does this manual cover?
It is the New Holland operator manual for the Workmaster 25 compact tractor, publication 51414247, with the S3L2-W461GT diesel. It runs 198 pages in English and covers both the mechanical transmission and hydrostatic transmission versions of the tractor.
How much oil does the transmission and hydraulic system hold?
The Maintenance section gives 30.0 L for the combined transmission and hydraulic system oil capacity, and the figure is the same for the mechanical and hydrostatic versions. p. 156
What is the wheel bolt torque on a Workmaster 25?
The Maintenance section specifies 176-196 N·m for both front and rear wheel bolts. Recheck them after any wheel tread change; wheel tread settings and tire inflation pressures are listed in the Specifications section. p. 135
Will this help me diagnose a fault before calling the dealer?
Yes. The Troubleshooting section runs symptom charts for the engine, clutch, mechanical service brakes, regulated and low pressure system, steering, hydrostatic transmission, and electrical system, with probable causes and corrections. It is an operator manual, not a component overhaul manual. p. 173
