Everything a TZ owner handles between dealer visits fits inside these 144 pages: the New Holland TZ25DA operator manual PDF, OEM 87544689, which also covers the TZ18DA and TZ22DA compact tractors along with the 54CMS and 60CMS mower decks. Lubrication and maintenance takes up roughly a quarter of the book, from fuel and lubricant service procedures to the same predelivery checks the dealer ran: tire pressures, fan belt tension, coolant level, battery. Wiring diagrams and a troubleshooting chart handle the electrical side, and both mower decks get their own full section for mounting, operation, and maintenance. Swap the hydraulic and HST oil filters at 300 hours, refill the crankcase with 3.3 liters after an oil filter change, and set rear wheel disc-to-axle bolts at 122 N·m. Every hour spent hunting numbers is mowing weather you don't get back. One purchase, one bookmarked, keyword-searchable PDF, yours for as long as you own the tractor.
Complete the set for your TZ18DA, TZ22DA, TZ25DA
