Why choose a SERCO road grader?

Do you need a road grader, but won’t build up a lot of operating hours or driving kilometres annually? Have you ever calculated the costs of a road grader per driven kilometre or operating hour? You should. One of the main advantages of the Serco Kerttu TL Road grader is its cost-effectiveness per driven kilometre or operating hour when compared to other heavy and expensive road graders on the market, especially if there won’t be a lot of driven kilometres or operating hours per year.

Additionally, the Serco Kerttu TL Road grader is a very long-lived investment and the need for maintenance is very small. It only has the technology necessary for achieving good results. An effort has been made to strip it of everything unnecessary or parts that easily develop faults in order to create a durable, low-maintenance and cost-effective grader.

The Serco Kerttu TL Road grader also has feature, which many other road graders on the market lack. This feature is appreciated by many and many professionals with long histories of grading have added this feature to their road graders themselves. It is driving the side blade at an over angle. This feature lets you e.g. handily shape the slope of a ditch.

Usability and efficiency as standard

The geometry of the Kerttu Road grader’s blades has proven to be good in practice. The two front blades remove the material from the road surface and pull it from the sides to the centre, effectively starting the mixing of the material already at the front of the grader. The last working blade is a long, one-part blade, which evens out the material together with the free-floating stone rake. The adjustment of the stone rake’s working height is independent of the devices other settings. The side blade is located right at the front of the device, allowing for the material from the side to effectively mix with the other material.

Working speed has a great effect on the grading result and it must always be adapted to the prevailing conditions and the surface to be graded.

 

Technology

During driving, the device’s tilt, side blade and working depth can be adjusted hydraulically from the cab. The tilt is used to shape the road surface so that it is angled towards the ditch and rain water won’t be left pooling on the road. The road grader is attached to the tow beams of the tractor and they are used to adjust working depth together with the hydraulic lift of the back end. Using the road grader requires 2 x double-action hydraulic blocks and a 1 x single-action block from the tractor.

The Serco Kerttu TL Road grader is available in one size. The road grader weighs 1,760 kg, but additional weights are available as accessories and the weight of the grader can be raised to over 3,000 kg. The blades have standard attachment (305 mm).

 
Well equipped

The Serco Kerttu TL Road grader has lights, a warning beacon and a hydraulic side blade as standard. Additional weights and various blade options, e.g. stinger blades, are available as optional extras for the Kerttu TL Road graders.
