Part of the New Holland Operator Manuals.
Which oil goes in each sump of the TD3.50, and when it comes back due, is settled by one document: the 216-page New Holland TD3.50 operator manual PDF, factory publication 48153455 for this tractor. Maintenance fills roughly a quarter of the book, organized by hour interval from the daily engine oil check to the 3600 hour coolant change, with capacities and consumables listed for every reservoir. Troubleshooting tables trace the engine, electrical system, rear three-point hitch and hydraulic service brakes from symptom to probable cause, while separate chapters handle the PTO, remote valves, ballasting and road transport. Fill the rear transmission, hydraulic lift and PTO housing with 23.0 L, then pull your wheel disc lock nuts to 220 N·m. Guessing an interval is free until it costs a component. Print the pages you need, let them get greasy on the bench, and keep the tractor ready when the weather opens.

New Holland TD3.50 Common Problems This Manual Covers
New Holland TD3.50 engine cranks slowly and will not fire in freezing weather
Test the battery charge and clean both terminals first; this tractor carries an 80 Ah battery (page 5), and a tired one will not spin the starter fast enough below zero. Confirm winter grade diesel in the 52 L tank, then follow the engine no start chart in the troubleshooting section starting on page 189.
Manual Section: Troubleshooting p. 189Steering wheel heavy or jerky at low engine speed, effort changes turning left and right
Check the hydrostatic steering reservoir oil level with the engine off; the system holds 2.0 L (0.5 US gal) per the capacity table on page 135. Top up with the specified fluid, then cycle the wheel lock to lock several times at idle to purge air. If effort stays heavy, inspect every hose connection for weeping seals.
Manual Section: Maintenance p. 135Engine down on power under load, black smoke and fuel consumption climbing
Remove the air filter element and hold it up to a light; if it is dark, clean it with compressed air kept below 72.5 psi (5 bar) blowing from the inside out, following the procedure on page 168. Replace the fuel filter cartridge if service is due, tightening it 3/4 of a turn (15 N·m) per page 166.
Manual Section: Maintenance p. 168Three-point hitch lifts slowly or will not raise a mounted implement, drops under load
Check the rear transmission oil level on level ground; the shared sump feeding the lift and PTO holds 25.0 L (6.6 US gal) with filter, per the capacities on page 135. Renew the transmission and hydraulic lift oil filter, tightening it 3/4 of a turn by hand as shown on page 155, then retest the hitch under draft.
Manual Section: Rear three-point hitch TroubleshootingCoolant level keeps dropping and temperature gauge climbs during heavy tillage work
Inspect the thermostat housing seal and every hose connection for seep marks with the engine cold; aging gaskets leak there first on this engine. Clean chaff and dust out of the radiator core before the season starts, and if the system has been drained, refill with the full 10.0 L (2.6 US gal) coolant charge listed on page 175.
Manual Section: Maintenance p. 175Frequently Asked Questions
