URBAN TR70 with double bagging

The branch logger URBAN TR70 is supported on the three-point hitch of the tractor. The optimum tractor power is 50 hp and more, the minimum power is 30 hp. The drive must be secured through a cardan with overload clutch (not part of the machine - you will find it in the accessories section). To reduce the impacts transmitted to the cardan and to the gearbox of the tractor we use a flywheel, which can be ordered as an accessories.


Part of the machine is: 50 pcs of raschle bags, safety chains, tow hitch with tow ball ISO50, operators manual including declaration of conformity.

The double bagging for raschle bags

It is used raschle bags of 57 × 104 cm. The flap can be switched between filling one or the other bag. After filling the first bag, there is no need to interrupt the job due to a full bag - just flip the flap and the chips fall further into the second empty bag. During the filling of the second bag it is possible to replace the first, already full bag. Continuous insertion of the branches allows to fill bag in 20 seconds. Optimal for the operator of the machine are 2-3 persons, one of them only changing the bags. We provide 50 pcs of raschle bags free of charge with each machine.


The inlet hopper

The inlet hopper consists of a fixed and a folding part. The folding part of the inlet hopper gives a narrower profile in the transport position (does not exceed the contours of the tractor in the transport position).  Once is locked in the working position the hopper ensures optimised branch intake and operational safety. Additionally, the hopper is fitted with a safety cut-out frame, which by pressing down stops the chipping device. The inlet hopper is oriented horizontally, which greatly facilitates insertion of long branches compared to the vertical or sloping hopper. Surface treatment of the whole machine is made with powder paint.


The connection to the tractor

The minimum recommended power of the tractor is 30 hp. The optimum tractor power is 50 hp or more. A tractor with this power can run at a low speed during chipping (about 1300 rpm). The tractor's output shaft is rated at 540 rpm. The resulting working speed of the chipping device is about 350/min. The speed of the chipping device corresponds to the speed of the cardan directly attached to the lower shaft of the chipping device. The drive must be secured through a cardan with an overload clutch set to a torque of 1600 Nm. The overload clutch which will slip and limit the torque when a large branch is fed into the hopper. Providing the tractor and the logger with protection from overloading.


The flywheel

The flywheel absorbs shocks transferred to the PTO and to the tractor gearbox. The machinery is standardly supplied without flywheel. The flywheel can be ordered as an optional accessory.


The adjustable frame

The adjustable sliding frame of the machine allows connection to various types of tractors while maintaining the optimal angles of the cardan (20 ° and 20 °).


The safety chains

The machine is lifted to the tractor hydraulics at the same working height (not on the ground) during working and moving. We use the safety chains chipper to assure machine in that optimal position. The safety chains are standard part of delivery with enach Branch Logger behind the tractor.


The chipping device

The working principle of branch loggers URBAN lies in two counter rotating shafts with knives. The rotating knives draw in the wood material into the feed hopper unassisted. The passage gap between the shafts is 70 mm. Each shaft has 3 fixed knives, made from high quality tool steel. It is possible to resharpen the knives repeatedly. After sharpening there is a pad to be put under the knives in order to keep the same gap between the knives (c. 0,1 mm). One single sharpening of knives is capable of producing from 100 to 500 solid meters of small logs, depending the level of contaminants (mud, nails, stones etc.). Each blade can be sharpened up about 4 mm, then it must be replaced with a new one.


The tow hitch

The Branch loggers attached behind the tractor can tow a trailer with a regular tow hitch or a tow ball ISO 50. The maximal weight of trailer is 2000 kg.


The branch logger is protected by industrial design.
