The hour meter on a Ford LS45-16G is the only honest record of when that foam air cleaner element came due, and this operator manual, Ford publication 42644510, is what turns the reading into a service schedule.
It runs 44 pages for the LS45-16G yard tractor: controls, parking brake, the power take off and the safety interlock system up front, then the maintenance you do yourself, engine oil and filter, spark plug, grease fittings, tire pressure, brake adjustment, fuel tank and filter, front wheel toe-in, fuses, headlights and battery. A wiring diagram and a troubleshooting section close it out.
Guessing costs more than the manual does: a wrong-size fuse, a toe-in set by eye, a spark plug torqued by feel. Download the PDF, find the spec, and get back to cutting before the grass gets ahead of you.

Ford LS45-16G, 9861899 Common Problems This Manual Covers
Starter does nothing with the seat empty
On these tractors the safety interlock circuit kills the starter when the operator leaves the seat, the power take off is engaged, or the brake is not set, and owners replace good starters over it. The Operation section walks the interlock system and the starting sequence so you can rule the circuit out first.
Manual Section: Operation p. 11Dash and hour meter go dead
A blown fuse takes out the dash and hour meter or the headlights, usually after a chafed wire or a corroded terminal. The Fuse section identifies each circuit: 5 amp for the dash and hour meter, 10 amp for the head lights, 25 amp for the alternator and 30 amp for main and starter.
Manual Section: Fuse p. 30Hard starting after the tractor sits
Gum from stale gasoline plugs the inline fuel filter, and the engine starves under load or dies on a slope. The manual calls for replacing the fuel filter every 100 operating hours or yearly, whichever occurs first, and the Fuel Filter section shows the hose clamp and fuel line work.
Manual Section: Fuel Filter p. 26Battery flat every spring
Low electrolyte and furred terminals leave the machine dead after storage, and a jump start hides the real fault. The Battery section covers electrolyte level, terminal and cable service, filler caps and hold down rods for the 12 v system.
Manual Section: Battery p. 32Front tires wearing on one edge
Toe-in drifts as the ball joints and jam nuts loosen, scrubbing the front tires and making the steering fight you. The Front Wheel Toe-In procedure gives the measuring method and the 1/8-1/4 inch setting.
Manual Section: Front Wheel Toe-In p. 29Uneven cut and soft steering
Unequal tire pressure tips the machine and shows up as a stepped cut and vague steering. The Tire Pressure section specifies 12 psi (.85 kPa) front and rear, checked at the valve stem on the stated service interval.
Manual Section: Tire Pressure p. 25Engine runs hot in heavy grass
Clippings pack the cylinder head fins and blower housing, the cooling air stops moving, and the engine loses power on a long cut. The Cleaning and Storage section covers clearing the fins and housing along with end of season fuel stabilizer and spark plug hole treatment.
Manual Section: Cleaning and Storage p. 34Frequently Asked Questions
Is this the right manual for my Ford LS45-16G?
Yes. It is the Ford operator manual for the LS45-16G yard tractor, publication number 42644510, 44 pages in English. Check the model number 9861899 on the model and serial number plate under the seat before you buy. p. 3
Does it include a wiring diagram?
Yes. The one-page Wiring Diagram lays out the ignition switch, switching relay, kill relay, indicator module connector and the brake and seat switches, which is what you need when the tractor cranks but will not run. p. 35
How often does the air cleaner need service?
The foam element is cleaned and re-oiled after every 25 operating hours, or yearly, whichever occurs first. The paper element is replaced after every 100 operating hours or yearly, whichever occurs first. p. 19
Does it cover engine overhaul?
No. This is an operator manual: operation, routine maintenance and adjustment. The Troubleshooting section works through a starter that will not crank, hard starting, power loss, overheating, abnormal vibration and a machine that will not drive, and sends transmission faults to the dealer, but internal engine repair calls for a service manual. p. 37
