Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland P1030, P1040, P1050 and P1060 tow behind air carts, two tank and three tank builds, 3rd edition from March 2014, part number 84329246 (replaces 87478740). Inside: the non powered rear axle (Section 27), hydraulics for the seeding fan, metering circuit and auger control valve (Section 35), wheels with real torque tables (Section 44), the split meter drive and product metering (Section 61), and product handling, fan and air distribution (Section 77). The electrical block is the reason to own it: harness and connector layouts, fold out schematic sheets with fuse legends facing each drawing, and a fault code chapter that walks every code through symptom, module and measurement steps.

New Holland P1030 to P1060 Common Problems This Manual Covers
Cart powers up but the metering clutches will not engage
Start with the Testing pages in Electrical - Controllers, Sensors and Actuators: they give the seeding control system and clutch circuit checks, then use the harness and connector diagrams to trace power past the fuse block, because good fuses do not clear the wiring between the module and the clutch.
Manual Section: Electrical - Controllers, Sensors and Actuators p. 551Low air velocity and constant plugging of fertilizer runs, even at high RPM
Before you touch the dampers, use the Hydraulic Seeding Fan System pages in Section 35 to confirm the fan circuit is actually making rated speed, then run the fan and check the lids and manifold for leaks; a worn lid seal will starve a run as fast as a slow fan.
Manual Section: Hydraulic Systems (Section 35) p. 126Product will not route correctly between tanks on double or triple shoot setups
The Air Distribution System pages in Section 77 lay out the manifold plumbing and gate positions for two and three tank carts by configuration, so you can match the plumbing under your cart against the drawings instead of guessing which gate feeds which run.
Manual Section: Seeding (Section 77) p. 972Application rate drifts or the two halves of the split meter do not match
Section 61 treats the Split Meter Control System, the mechanical drive and product metering as separate procedures, so you can rule out drive slip and meter wear first, then follow the control system checks in order before you start replacing electronic parts on a hunch.
Manual Section: Metering System (Section 61) p. 184Frequently Asked Questions
Does the manual cover fault codes, and how do I clear them on these carts?
There is a dedicated fault code chapter that takes each code through its symptom, the control module involved and the actual measurement steps at the connectors. Codes clear once the fault condition is fixed; the value of the book is telling you what to measure so you fix the cause instead of cycling power and hoping. p. 551
My cart powers up but the clutches will not engage. Will this manual actually help?
That exact complaint shows up on the forums: power present, fuses fine, no clutch engagement. The Testing pages in the electrical section give the seeding control system checks, and the schematic sheets with connector legends let you trace the clutch circuit from module to coil instead of swapping parts blind. p. 207
What are the wheel torque specs for the P1030/P1040/P1050/P1060?
They are in the book and they are cart specific: rear wheel bolts torque to 440 Nm (325 lb ft) on the 12,000 lb rated rim and 217 Nm (160 lb ft) on the 7,500 lb rim, both rated at 10 mph. The Wheels section (44) carries the tables along with rim weights. p. 126
Are full wiring schematics included?
Yes. The schematic frames print as double width fold out sheets with the connector and fuse legends facing each drawing, so you are not flipping pages mid trace. Harness routing and connector location pages back them up, which matters on a cart where most faults end up being wiring. p. 184
Which models and years does this edition cover?
It covers the P1030, P1040, P1050 and P1060 tow behind air carts in both two tank and three tank configurations. This is the 3rd edition from March 2014, part number 84329246, replacing the earlier 87478740. It applies to the electronic metering generation of these carts rather than a listed year range. p. 6
