New Holland T4.80F, T4.90F, T4.100F, T4.110F, T4.80LP, T4.90LP, T4.100LP & T4.110LP Tractor PDF Repair Service Manual (PIN ZHLH00094 & Above)

Not every specialty tractor is engineered around the same priorities. The New Holland T4 F and T4 LP Series were developed for growers who spend long days working between closely spaced orchard rows, vineyards, olive groves and other permanent crops where tractor width, turning ability and hydraulic precision are just as important as engine performance. Compared with conventional utility tractors, these machines feature a narrower chassis, low-profile configurations, compact front axle geometry and balanced weight distribution to maintain stability on uneven terrain while operating sprayers, shredders, side mowers and hydraulic implements.

Because of this specialized design, servicing these tractors requires more than general mechanical knowledge. Hydraulic routing, MFWD components, steering geometry and PTO assemblies are packaged within a compact frame, leaving little room for error during repairs. The OEM Factory Repair Service Manual (Publication No. 51523358) provides dealership-level procedures for tractors beginning with PIN ZHLH00094 and above. Every repair operation follows factory specifications, helping technicians inspect, diagnose, dismantle, rebuild and verify components exactly as intended by New Holland engineers.

OEM Manual Technical Specifications

Why Experienced Mechanics Depend on This Edition

Repairs on specialty tractors often involve assemblies that are unique to orchard applications rather than standard agricultural machines. This factory manual combines exploded component illustrations, inspection dimensions, adjustment values, hydraulic circuit diagrams and troubleshooting sequences into a single workshop reference. Whether replacing a PTO clutch assembly, rebuilding a front drive axle, tracing an electrical fault or overhauling the hydraulic system, technicians can follow the same repair workflow used by New Holland service departments.
