Compatible decks can be adjusted from approximately 1 inch to 5 inches.
How many cutting-height positions are available?
The mower provides 17 cutting-height positions.
How large are the cutting-height increments?
The deck adjusts in approximately 1/4-inch increments.
What type of deck suspension does the H27i use?
Compatible decks use a Torsion-Flex frame with caster wheels and counterweight springs.
What are the benefits of Torsion-Flex deck suspension?
It allows the deck to follow changes in terrain independently from the tractor, supporting 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 a quick-disconnect PTO shaft?
It simplifies deck changes and makes it easier to connect compatible Walker implements.
How are the cutting blades engaged?
The H27i uses a manual belt-tightener clutch.

Can the Walker H27i mow on slopes?
It may be used on appropriate slopes within Walker’s stated operating limits. Wet turf, loose ground and abrupt turns can reduce traction.
What conditions can affect zero-turn mower stability?
Slope angle, moisture, hidden holes, tire condition, mowing direction, speed and operator technique can all affect control.
What size drive tires does the Walker H27i use?
The drive tires measure approximately 23 inches by 10.5 inches on 12-inch rims.
What size tailwheel does the Walker H27i use?
It uses a 13-inch by 5-inch pneumatic four-ply tailwheel.

That depends on the installed deck. The tractor is 46.5 inches wide, while an R64 configuration is approximately 66 inches wide.
What should I measure before buying a Walker H27i?
Measure gates, pathways, trailer ramps, storage doors and the narrowest areas where the mower will operate.
Can the Walker H27i be transported on a trailer?
Yes. Use a trailer with enough width, payload capacity, ramp strength and secure tie-down points for the tractor and selected deck.
Can the mowing deck be tilted for service or transport?
Walker’s front-mount deck design allows compatible decks to be tilted for improved access and reduced storage length.
What are the benefits of a tilt-up deck?
It makes blade inspection, deck cleaning and underside maintenance easier.
Can the Walker H27i use attachments other than mowing decks?
Its quick-disconnect PTO and front-mount configuration may support compatible Walker attachments. Exact compatibility should be confirmed before purchase.
