Part of the New Holland Operator Manuals.
The rear three-point hitch is where most Powerstar questions start: draft control that will not settle, lift arms sitting wrong for the baler, a top link pin you cannot verify by eye. The Working Operations section of this New Holland operator manual covers all of it, plus the rear PTO, remote control valves, tread settings, and front loader, with actual pin diameters and clearances printed on the page.
The rest of the book covers the whole tractor: controls and the display, starting and road transport, a full maintenance schedule with capacities and fuse locations, fault code troubleshooting, and specifications. It applies to the Powerstar 90, 100, 110, and 120, serial number ELRT5100PJLE50082 and above, publication 51594050, 368 pages in English.
When the hitch will not drop at dusk and there is nobody left to call, this PDF opens on a phone in the cab and gets you back in the field.

New Holland Powerstar 90, Powerstar 100, Powerstar 110, Powerstar 120 Common Problems This Manual Covers
Rear hydraulic lift slow or unresponsive
Implements that raise sluggishly or will not hold position are a common complaint on these tractors. The Troubleshooting section walks hydraulic system symptoms back to causes, including the rear hydraulic lift and service brakes.
Manual Section: Troubleshooting p. 323PTO shaft does not match the implement
Switching between 540 and 540E work, or hooking up a new baler, often stalls at the PTO stub. Working Operations covers changing the PTO shaft and attaching PTO-driven equipment step by step, along with the rear remote valves.
Manual Section: Working Operations p. 157DEF warnings and engine derates
A clogged DEF line filter or contaminated fluid will put the SCR system into a derate right when you need full power. The Maintenance section covers cleaning and replacing the DEF/AdBlue filters and changing the tank fluid.
Manual Section: Maintenance p. 229Display shows wrong speed or area
If the dashboard readouts drift after a tire change, the fix is recalibration, not a sensor. Controls and Instruments explains calibrating speed and tool width through the display, plus adjusting brightness and the buzzer.
Manual Section: Controls and Instruments p. 69Soft or uneven brake pedal
A pedal that sinks or pulls to one side usually traces to fluid level or pedal adjustment. The Maintenance section covers filling the brake fluid reservoir and checking the brake pedals on schedule.
Manual Section: Maintenance p. 229Hard starting on cold mornings
A tractor that cranks but will not fire in winter costs you the best hours of the day. Operating Instructions covers the correct starting procedure, and the Accessories section describes the coolant immersion heater for cold climates.
Manual Section: Operating Instructions p. 137Frequently Asked Questions
