GM 4 Caterpillar

Drainage channels, drainage or pitch heating for soccer stadiumsDrainage channels, drainage systems or pitch heating for football stadiums - the trencher Grabenmeister GM4 crawler is an all-rounder

Versatile, even in hot, impassable or mountainous regions. This modern trencher is the reliable machine. Especially when it comes to trenches or channels.


Equipped with an all-terrain four-wheel drive in the basic version, the tracked version offers even more safety, precise driving comfort and optimum load distribution. The trencher with chain drive feels at home on the edge of the field where a drainage channel is planned. But also on the football pitch, where it cuts the channels for pitch heating - without ruining the turf.

The technically sophisticated equipment of the Grabenmeister GM4 crawler

An economical but very lively 4-cylinder diesel engine provides propulsion and sufficient power on the milling chain. Therefore, even heavy clay soils or muddy terrain are hardly a challenge for this flexible machine. The excavated material is ejected to the desired side. Via a conveyor belt, it can also be disposed of directly onto an accompanying vehicle, which you can rent together with the trencher.

Time saving with a hopper

The optional hopper on the GM4 caterpillar saves time. The trench is milled and immediately filled with gravel in one step. At the same time, the drainage pipe can be laid using a reel with pipe guide. This ensures the optimum position of the drainage in the channel and three operations are carried out in one go. The sole scraper with plates and the dozer blade are also part of the complex scope of delivery.

Special advantages of the GM4 with crawler drive

For better manoeuvrability, the chassis camber was designed in such a way that it also compensates for rough uneven ground. Compared to the wheel drive, the tracked version of the trench digger has considerable advantages. These include in particular the even weight distribution of the machine. The 4,900 kilograms caused by one chain cause only minimal damage, which is why the crawler is indispensable for use on sports grounds, for example. This is why the GM4 crawler trencher is offered for hire with operating personnel.

The GM4 crawler trenchers can be used on tracks on slopes without any problems. The vertical adjustment provides additional stability. The intelligent tilt system compensates for lateral slopes of up to 12° using the powerful hydraulics. The adjustable operator's platform is advantageous for difficult applications. It can be moved to the left and far forward, giving the operator a direct view of the milling chain and trench.

As a crawler, the Grabenmeister GM 4 can cope with a wide range of requirements. The flexible machine can be set to milling depths of 600, 800, 1250 and 1500 mm. There is a choice of milling chains with blade carbon bits or as a mixed chain. Milling widths from 70 to a maximum of 450 mm are possible.

Additional equipment for the GM4 crawler trencher

In the basic configuration the GM4 is designed as an open ride-on unit. In this version you can also rent this trencher. The model is also available with four-wheel drive or powerful caterpillar drive. Optionally, a driver's cab can be mounted as weather protection. This is always equipped with a particularly comfortable driver's seat. If the mobile milling machine is purchased for year-round use, we recommend installing the heating system. Almost luxurious, but indispensable in hot countries, the trench master is also offered with an air conditioning system for the driver's cab.
