Post Extraction using Land Rover & Winch

Among the offroad vehicle fraternity the use of a winch to extract a stuck vehicle is commonplace and this low cost equipment can also be turned to the advantage of the small woodland owner / operator to winch out logs from difficult places and positions where horse logging might prove difficult.

Image

The Oxfordshire Woodland Group part grant funded the purchase and fitting of an electric bumper mounted winch to Andrew Jarvis's Land Rover and this was demonstrated in action at the OWG 2016 horse logging event.

Image

The Land Rover engine is kept running whilst winching together with the driver having to be positioned in the cab with his foot on the brake to prevent movement of the vehicle. During the more difficult parts of this operation it is adviseable to have a banksman in place to signal to the driver instruction on progress of the extraction

Image

Once the log is on the level the winching load drops -

- and when the log is fully level on the ride the need for the driver to sit with his foot on the brake also eliminated.

2 weeks later the Land Rover and winch were put to the test pulling out a 23ft x 800lb long crook European Larch log on a very wet misrable grey day that is destined to be hand hewn to form a cruck blade.

Image

This very heavy log was supported on rollers to ensure that it was not dragged along the ground where it would have been coated with mud and flints.

Image

The Land Rover was pulled well back and the winch cable extended to ensure that a good straight extraction run could be acheived.

Image

The supporting rollers were leap frogged from the rear to the front of the log as it was pulled by the winch.

Image

This technique helps to ensure that the ground is not rutted by the log being extracted.

Image

When the cruck log had reached the Land Rover the winch was released.

Image

The Land Rover then pulled back to the log pile where the cruck log was destined to be stored before it is pulled onto the hewing bunks.

Image

This whole process was then repeated only this time two straight medium sized logs were pulled out in tandem.

Image

The logs in the storage pile are raised off the ground on bearers to ensure that wet conditions that would encourage rot and long horn beetle infestation are avoided.

Image

Logs ready for debarking and hewing.

Image

This investment by The Oxfordshire Woodland Group in a members land Rover (Series II) has already proved its worth for log extraction and wire fence tensioning and is undoubtedly a good low cost multi task option that can be considered by small woodland owners to help move a small numbers of heavy logs.
