Part of the New Holland Repair Manuals.
A garden tractor that cranks but will not fire, or a hydro that creeps in neutral, comes down to a spec you do not have. The New Holland MY16, MY17, MY19 repair manual PDF, OEM 87045362, puts the answer, 166 pages of it, in front of you. Wiring diagrams close out the book, tracing the relay, ignition switch, seat switch, brake switch, and electric PTO clutch circuits so you can chase a no-crank with a meter instead of a parts cannon. Transaxle work runs longest, from a troubleshooting checklist through brake adjustment, then chassis jobs: front wheel toe-in and tilt steering. Fill the hydrostatic transaxle with 3.8 quarts of SAE 20W-50, and check cranking amps before blaming the starter: 260CCA on the 16, 340CCA on the 17 and 19. Out in the barn, there is nobody to ask. Buy the bookmarked, text-searchable file once and it is yours for the life of the tractor.

New Holland MY16, MY17, MY19 Common Problems This Manual Covers
New Holland MY16 starter clicks once but engine will not crank, headlights dim when key is turned
Check battery voltage and clean both cable terminals before condemning the starter. Load test the battery; the MY16 calls for a 260CCA battery per the specs on page 6. Then check start relay coil resistance following the procedure on page 104; a good coil reads 70 to 90 ohms. Replace the relay if it reads open.
Manual Section: Electrical System p. 104Electric PTO clutch will not engage, mower blades stay stopped with switch pulled and engine running
Test the PTO clutch coil with an ohmmeter following the procedure on page 110; a good coil measures 2.40 to 3.40 ohms. Then check current draw with the engine running; the clutch should pull 3.5 amps or above. If resistance is fine but current is low, chase the PTO switch, seat switch, and wiring first.
Manual Section: Electric PTO Clutch Testing p. 110Hydrostatic transaxle whines and loses drive on hills after twenty minutes of mowing
Check the transaxle oil level and top off with SAE 20W-50 API SH/CD oil as listed on page 10. If the oil is dark, drain and refill per the procedure on page 27; a full change takes 0.95 gal. (4.3 l). Purge air by cycling the pedal slowly both directions with the drive wheels off the ground.
Manual Section: Transaxle p. 27Tractor creeps forward in neutral and brake pedal will not hold on a slope
Adjust the brake before buying parts. Block the front wheels, back off the adjustment nut, and set brake clearance to 0.020 in. (.508 mm) with a feeler gauge, following the procedure on page 32. Torque the brake nuts to 80 to 120 lb-in when finished, then confirm the pedal locks both rear wheels on a slope.
Manual Section: Brake Adjustment p. 32Steering wheel has excessive free play and front tires wear unevenly and scrub during turns
Measure free play at the steering wheel rim; more than 0.5 to 1.0 in. (13 to 25 mm) means adjusting the steering gear eccentric, covered on page 87. Then set front wheel toe-in to 1/8 to 1/4 in. (3 to 6 mm) at the tie rod ball joints per page 66. Grease the spindles while the front end is up.
Manual Section: Chassis p. 87Frequently Asked Questions
What are the torque specifications for fasteners on the MY16, MY17, and MY19 tractors?
Torque specifications vary by fastener grade and size. For example, a 1/4-20 UNC Grade 5 bolt requires 100 ± 10 in-lb, while a 3/8-16 UNC Grade 5 bolt requires 30 ± 3 ft-lb. Detailed tables for inch and metric series fasteners are provided on pages 12 and 13. p. 12
What is the transaxle oil capacity on the New Holland MY16 / MY17 / MY19?
The transaxle has an oil capacity of 3.8 quarts (3.6 liters). When performing a fluid change, the required volume is 0.95 gallons (116.5 oz or 4.3 liters) of 20W50 engine oil. p. 27
How often should the New Holland MY16 / MY17 / MY19 be greased?
The machine should be greased every 50 hours or yearly, whichever occurs first. You should grease more frequently if operating conditions are extremely dusty or sandy. p. 20
What is the correct transaxle brake adjustment procedure on the New Holland MY16 / MY17 / MY19?
To adjust the brake, remove the cotter pin and loosen the castle nut slightly. Insert a 0.020 inch (0.508 mm) feeler gauge between the outer brake pad and rotor disc, then tighten the adjusting nut until slight resistance is felt on the gauge. p. 32
What is the specified front wheel toe-in on the New Holland MY16 / MY17 / MY19?
The front toe-in measurement should be 1/8 inch to 1/4 inch (3 to 6 mm). This should be checked every 100 hours or once a year, whichever occurs first. p. 66
