Honda Brushcutter UMR 435 LT

Characteristics
Designed for intensive use, with all the advantages and comfort offered by Honda 4 stroke technology, with constant power and torque, for all the most demanding working conditions.

Non-contact sealing bearing. Used by NASA , this type of bearing offers the best resistance against dirt in high-speed applications. Contact with the rotating part is avoided so that the seal does not heat up as happens with full contact rubber seals and thus reduces the useful life of the seal, as well as its anti-dirty function.

6-tooth drive shaft. This type of shaft offers the best torque transmission to the cutting accessory, reducing the occurrence of shaft breakage compared to a traditional key-slot drive.

Anti-vibration clutch. Honda's development team designed a two-part clutch block and installed an anti-vibration damper in the middle. Engine vibrations are absorbed and are not transmitted to the handlebars, offering the user a higher level of comfort.

Torx Screws The 12,000 rpm at which the cutting accessories rotate require the brushcutter to be equipped with screws resistant to high frequency vibration. These special head screws withstand greater tightening torque during assembly and maintain the screw's tightening characteristics despite the high vibration frequency of the cutting accessory.

Why choose a 4-stroke engine instead of a 2-stroke?
Here are 5 reasons why you should opt for 4-stroke technology:

1. Ease of start-up
Ease of starting is achieved through a mechanical decompression system combined with an ultra-low weight flywheel, resulting in a manual rope starter weighing just 7.2 kg, the top of the class. As a comparison, it requires around 45% less force to pull than a traditional 2-stroke engine.

2. Reduced noise levels
Compared to products from leading 2-stroke engine manufacturers, the noise levels of Honda 4-stroke engines are between 17 and 50% quieter and the sound frequency is lower, without that characteristic "high-frequency hiss", the which provides a quieter usage environment, right from the start. This level of performance is achieved thanks to a belt-driven overhead valve design (which reduces mechanical noise), a large capacity multi-chamber exhaust system (to reduce exhaust noise) and a sophisticated intake system. (reducing air intake noise at high speed).

3. Reduced running costs, easier setup and maintenance
In a 4-stroke engine, it is not necessary to previously mix oil with gasoline. Just fill the tank with gasoline. For best performance, it is recommended to change the oil every 50 hours. On average, oil consumption will be reduced by 85% when compared to 2-stroke engines, resulting in savings in fuel and oil.

4. Lower fuel consumption and more time without refueling
In Honda 4-stroke engines, fuel consumption is approximately 33% less every year compared to 2-stroke engines from leading manufacturers.
Consumo de combustível à potência máxima
Honda 4-stroke engines (0.5 liters/hr)
2-stroke engines (0.8 liters/hr)
The Honda GX25 and GX35 micro engines are equipped with fuel tanks of 0.55 and 0.65 liters respectively, while 2-stroke engines from leading manufacturers have fuel tanks of around 0.39 and 0.53 liters for the same power. of engine. The lower consumption and greater capacity of the fuel tanks means that the periods between refueling are multiplied by 2.1 and 1.6 respectively.

5. Less smell and fewer emissions
Our 4-stroke engines generate 85% less hydrocarbons and nitrogen (NHC) and nitrogen oxides (NOX) than 2-stroke engines. Our engines do not use catalytic converters; Unlike catalytic converter technology, our 4-stroke technology does not need to wait for the exhaust to heat up to perform better. And, unlike most 2-stroke engines, there is no build-up of particles in the exhaust, which can cause blockages and reduce engine performance.

Brushcutter backwards. Designed for excellent maneuverability and comfort. This back brushcutter was designed to meet the demands of commercial environments, where full maneuverability of the cutting head is required. The weight of the engine has been distributed evenly across the user's waist and shoulders, meaning they will quickly appreciate the comfort during the first few minutes of use. The cutting head, driven by a flexible shaft, makes working on steep slopes, orchards, vineyards, parking lots and bushes easy. This back brushcutter is equally easy to use in confined garden areas.
