At this point in time, there is a lot of uncertainty over what will happen in the future with regards to UK legislation and standards post-BREXIT. For now, however, the UK must follow the EU rules

Toro’s Stage V compliant ProLine H800 direct collect outfront rotary mower
The Groundsmaster 3200 and 3300 (shown with flail attachment here) lead the first wave of new Stage V emissions compliant machines
avoid any restriction on when they can be retailed to an end-user. Stage V closely follows the Tier IV standard that was introduced in North America several years ago. Whilst there are similarities, Tier IV and Stage V are two different standards.
What is the difference between Stage V and previous EU emissions standards?
It’s an evolution of previous standards and requires controls to be applied to new non- road mobile machinery. It will ensure limitations of carbon monoxide, nitrogen oxides and hydrocarbons, as well as diesel soot emitted to the atmosphere. The biggest change with Stage V from previous standards is that it captures all spark ignited (SI) and combustion ignition (CI) engines, where previous standards did not.
What impact do these regulations have for the customer?
The essence of the regulations are, of course, good - cleaner air is something we should all be supportive of and active in achieving, but the fact of the matter is these changes do have a significant effect on the product, particularly those with diesel engines rated above 19kW and fitted with DPF systems.
The engines are more complex and follow the type of engine management systems

that we associate more with the automotive sector. However, diesel engines in the sub- 19 kW category and SI engines witness much less of an impact, which prompts manufacturers to look at whether a product can meet customers needs with less horsepower or migrate to alternative fuels. We’re expecting a period of uncertainty with customers as they assess the way they maintain their grounds/contracts, considering requirements, mowing options, budget, etc. It will become crucial to consider the ‘real mowing’ productivity of the machine, something tenders have already started to add into the process. For example, is there a different way to compile a fleet or can different purchasing decisions be made that allow customers to remain profitable and productive? It might cost more to buy a specific machine, but if you only need to buy one machine to perform more than one function or a machine like the Toro LT-F3000 triple flail, which is so productive it can enable you to reduce the cutting frequency, those factors become more important than ever.
What has Toro been doing since it knew these changes were coming?
Toro benefitted from its experience with the roll-out of Tier IV products in North America. We learned how to design out inefficiencies in systems such as, but not limited to, hydraulics, engine cooling, etc. We’ve
focused on how we can deliver a range of efficient, capable solutions to our customers, so they can select the right machine for their requirements. For example, we have reduced the horsepower of our CT2240 compact triple from 19kW to 18.7kW, a reduction of only 1.5 percent, but a reduction that allows us to avoid the added cost and complexity of a DPF filter. Despite the reduced power output compared to its bigger brother, the LT3340, the CT2240 offers many of the same features, the same width of cut and will also, [for 2021] be available with the larger 250mm (10ins) diameter cutter units, which were previously limited to the LT3340. We feel this offers the customer an interesting value proposition - will they be willing to accept a product that can achieve over 80- 90 percent of what the LT3340 can, and benefit from the simplified power train and lower cost? Less horsepower could also result in lower fuel consumption and lower operating costs. Stage V will certainly shake-up the market, so it’ll be interesting to see how customer requirements and preferences adapt and change over the coming months and years. In contrast, we’ve upped the power of the
Toro LT3340 heavy-duty triple mower from 26kW to 27.5kW, giving customers the option to buy a machine that can now do more. If customers are having to pay more,
