What are the benefits of dual fuel tanks?
The dual-tank design provides extended operating time and allows the operator to switch between tanks during the workday.
Is the Walker H24d fuel efficient?
Yes. Diesel power and the mower’s high-production design make it well suited to operators focused on fuel efficiency and return on investment.
What battery does the Walker H24d use?
It uses a 12-volt battery rated at 340 cold-cranking amps.
What charging system does the H24d use?
It uses a regulated flywheel alternator.
What is the charging output?
The charging system produces up to 30 amps DC.
What transmission does the Walker H24d use?

What are Hydro-Gear ZT-3400 transaxles?
ZT-3400 transaxles are commercial-grade hydrostatic drives designed for smooth control, durability and serviceability.
What are the benefits of dual independent transaxles?
Each drive wheel is powered separately, providing precise steering, zero-turn maneuverability and infinitely variable speed control.
Is the Walker H24d a zero-turn mower?
Yes. Its independent hydrostatic drive system allows tight zero-turn handling.
How is the Walker H24d steered?
It uses individual hand levers to control the left and right drive wheels.

Yes. It includes a precision friction-lock forward-speed control with cruise control and a neutral-park position.
How fast does the Walker H24d travel?
It can travel from 0 to approximately 10 mph, or 16 km/h.
What does infinitely variable speed mean?
It means the operator can select any forward speed within the mower’s range rather than choosing from fixed gears.
How is the parking brake operated?
A single lever engages an internal mechanical lockout in each transaxle.
Can the transaxles be released for manual movement?
Yes. Manual dump valves allow the drive system to be released when the mower must be moved without engine power.

What type of deck suspension does the H24d use?
Compatible decks use a Torsion-Flex frame with caster wheels and counterweight springs.
What are the benefits of Torsion-Flex deck suspension?
It helps the deck follow changes in terrain independently from the tractor for a more consistent cutting height.
What do the counterweight springs do?
They help balance the deck and reduce the effort required to raise or tilt it.
What is the quick-disconnect PTO shaft?
It is a splined shaft with two high-speed universal joints that transfers engine power to the deck or attachment.
What are the benefits of the quick-disconnect PTO system?
It simplifies deck and attachment changes while providing a strong mechanical power connection.
How are the mower blades engaged?
The H24d uses a manual belt-tightener clutch.

Why is a utility bed useful on a commercial mower?
It reduces trips back to a truck or maintenance building and helps operators carry common tools during the workday.
What size drive tires does the Walker H24d use?
The drive tires measure approximately 23 inches by 10.5 inches on 12-inch rims.
What size tailwheel does the Walker H24d use?
The supplied specifications list a 23-inch by 10.5-inch tailwheel configuration.
What size deck caster tires are used?
Compatible decks use 13-inch by 5-inch pneumatic four-ply caster tires.
What are the benefits of pneumatic deck caster tires?
They provide cushioning and help the deck travel more smoothly across uneven ground.
Is the Walker H24d suitable for rough terrain?
Yes. Its large tires, heavy chassis, suspension seat and independent deck suspension make it suitable for moderately rough commercial properties.
Can the Walker H24d mow on slopes?
It may be used on appropriate slopes within Walker’s stated limits. Wet turf, loose soil and abrupt turns can reduce traction.
Does the Walker H24d have a ROPS?
