Product details

Discover the Steiner 450's powerful engine and hydraulics, wide stance, articulating + oscillating chassis and new hydraulic weight transfer system - and you'll be hooked!

The Steiner 450 is the perfect workhorse for New Zealand orchards, mowing contractors, lifestyle blocks and areas where normal mowers just won't go.

The Ultimate in Slope Safety


With a slope rating of up to 58% or 30° (depending on configuration), you will always be comfortable and secure mowing or landscaping in areas previously inaccessible or unsafe. The Steiner has a range of tyre configurations available to maximise traction and stability, with the dual tyres popular for increasing up to the 30 degree slope limit.

Oscillating + Articulating (Pivot Steer)

An oscillating chassis makes this machine safer when driving over undulating terrain and obstacles such as rocks, by acting to keep the centre of gravity lower and therefore the mower more stable.

The Steiner is the ONLY tractor with infinitely variable hydraulic down pressure adjustment

With machines of this type, it is important that ground pressure can be adjusted depending on terrain and conditions. With the Steiner, you get a very unique, custom designed hydraulic weight transfer system that enables you to change the ground pressure while on the go with a simple dial and gauge. This means that you can adjust the way the mower reacts in soft, muddy and undulating ground or hard, flat areas - giving you a neat mowing finish and optimum stability. No tools required (unlike other brands).

Multiple uses on multiple parts of the property

The quick hitch attachment system enables you to turn the Steiner into an indispensable workhorse for your rural property or business - an all-seasons machine that takes over 25 attachments like mowers, buckets, scrapers, sweepers, trenchers and more. Go from digging fence posts to laying irrigation channels to mowing overgrown weeds in minutes.

Comfortable, dependable and easy to use

In 2017 The Steiner 450 tractor was completely re-engineered to provide even more power, versatility and dependability to users in residential, farm, golf, city council, landscape and sports turf industries. The tractor boasts an articulating frame, giving it a tight turning radius of only 43.5 inches/1105mm. The frame also oscillates, keeping the operator upright and in control even on the most uneven terrain. With plenty of power, excellent traction, a low centre of gravity and wide stance, it’s built for maintaining hill terrain and operating where other tractors typically can’t.

Plenty of power

To power this machine’s top-level performance, customers can choose from three reliable engines: a Kubota® 25- horsepower, liquid-cooled diesel; a Kubota® 32-horsepower, liquid-cooled gasoline; or a 37-horsepower Vanguard EFI™ air-cooled gasoline engine. A new, stacked gear pump design dramatically increases durability, hydraulic performance and efficiency. It also offers increased oil cooler capacity and reduced drive system pressure. Providing 1,750 PSI of steering and lift pressure for more hydraulic power, it can handle the toughest chores.
