Murray Garden Tools was purchased by US lawn mower manufacturer Briggs and Stratton in 2014, and while it continues to operate under the Murray brand the lawn mowers now use the same engines featured in the best-selling Briggs and Stratton petrol mower range.

Murray EQ 400 18"/46 cm Petrol Push Lawnmower Review

This is good news for UK buyers, bringing some of the best quality petrol lawn mowers to the market. These mowers are known for their exceptional power, allowing them to easily mow through tough and overgrown lawns, including lawns that are very wet – a great selling point considering the infamous British weather!

The Murray EQ 400 is a mid-size petrol lawn mower suitable for lawns up to 1000m2. This makes it ideal for larger sized lawns here in the UK, with the excellent power making short work of even the poorest condition lawns.

Let’s take a closer look at the Murray EQ 400 to see what it offers:  


  • Briggs & Stratton 125CC Petrol Engine
  • 46cm Cutting Width
  • 6 Cutting Heights (28mm to 92mm)
  • 60 L Grass Catcher
  • Ergonomic Handle


The EQ 400 is fitted with a Briggs & Stratton 125cc 450e series petrol engine, offering exceptional cutting power and speed. Petrol powered mowers such as this are always best used on larger lawns with massive surface areas, highlighted by the fact that this one is suitable for areas up to 1000m2.

While most garden lawns are smaller than this, there is still plenty of use from buying a petrol mower like this, namely the unrivalled cutting power it provides. The petrol engine produces 6.1nm of torque, delivering high power and speed to the cutting blade, allowing it to effortlessly cut through long and damp grass – this is great for maintaining overgrown lawns.

As it is powered by a petrol engine you do need to manually start the motor. The recoil cord is responsive, powering the mower the first pull in most instances, so starting the engine shouldn’t require much effort.

Of course, as a petrol engine the mower does produce noise and emissions, although it is fitted with a Lo-Tone muffler to ensure compliance with EU standards.  

Cutting Width

Fitted with a 46cm steel blade, the EQ 400 has a wide cutting width that is well suited for large lawns. It is intended for use on huge surface areas, so it is good that an appropriately sized blade has been used, ensuring large portions of the lawn are mowed with each pass, helping to keep mowing time to a minimum.

The blade is also slightly curved, giving it better suction to help reduce clumping, which is often a problem when mowing long and wet grass. It produces a clean and precise cut across the grass, leaving a uniform finish even when working on overgrown and weedy lawns. 

Cutting Height

The EQ 400 has a unique high lift blade design that makes it more efficient when mowing longer grass. Without a high enough blade position, long and wet grass often gets missed, so this feature ensures that the mower can easily handle longer growth this is more common on larger lawns.

At 92mm, this is higher than most other lawn mowers, emphasising how suitable it is for long and wet grass, which normally clumps around the mower blade if not positioned high enough.

You can adjust the blade position at both the front and back of the mower deck. There are levers at the front and back, each one adjusting the front/rear wheels into various heights, with six positions to choose from.

This means you can cut grass of varying heights, getting the perfect finish to ensure it looks great and grows back healthy.


Petrol lawn mowers such as this are always going to be more challenging to operate compared to their electric counterparts. Because it features a petrol engine, the EQ400 is heavier than your average electric mower, although it remains relatively lightweight for a petrol mower at just 25kg.

In fact, 25kg is considered lightweight for a petrol mower, and this one does not require all your strength to push and pull around the lawn. There is no self-propulsion feature, highlighting that the mower is light enough to operate without this feature, although it will require some effort to move up and down sloped areas of a lawn.

Beyond this, the mower is simple to operate. You don’t need to exert a lot of effort to move it around, with it easily making turns at various angles.

Starting petrol mowers can be challenging for many users, although this is not an issue with the EQ400. The recoil start system is very responsive, starting the engine on the first pull of the cord in most instances.

Grass Collector

The EQ 400 comes with a 60L grass collection bag, which is a suitable size for a mower designed to handle longer grass. Long grass on a larger lawn means a lot of clippings to deal with, so the spacious capacity of the grass collector saves the hassle of constantly stopping the mower to empty the clippings.

In most cases, you will not need to empty the grass collection bag until you are a finished mowing, unless working on extra-large surface areas.

There are not any additional features with the lawn mower, which is not much of an issue considering the reasonable price point. The high lift blade position means it is not best suited for mulching anyway, although you can purchase a mulching plug separately if you want this function.


  • Powerful petrol mower for a reasonable price
  • Lots of cutting power is great for long and dense lawn growth
  • Easily mows damper lawns
  • One of the lighter petrol mowers on the market
  • Easy to start


  • Mulching function is not included but you can purchase a plug separately.
