All mole ploughs have a unique pitch adjuster on the leg to ease pulling and a shearbolt safety mechanism. They all run on beams with replacable wear skids and have alot of clearance around the leg with a heavy duty disc so there is no chance of any trash build up.They have a double ended leg with replaceable shin and mole foot.
Single Leg Mounted -
To suit 150 - 250hp tractors
The single leg mounted machine has long beams with four hitch hole settings for different makes of tractor, the tractor needs to be hitched in the lowest hole as possible to pull the weight down onto the tractor for grip. It also has a swing arm onto the top-link to let the moler run freely over uneven ground and alter the angle of the mole when coming to lift out of the ground to guide the moler out smoothly.
Single Leg Trailed -
To suit lower hp crawlers or 200hp+ wheeled tractors
The single leg trailed is the same design as the mounted version with shorter beams to ease pulling because of the drawbar length. The machine has a hydraulic drawbar and lifting wheels to guide the moler in and out the ground smoothly. The weight cant be transfered onto the tractor as much with a drawbar machine which is why it would need a higher hp tractor to pull it and is better suited to a crawler.
2 Leg Mounted - avaliable in 2m and 2.6m spacing
To suit 300hp+ tractors and crawlers
The twin leg mounted Is based on the same principle as the single leg with the 4 hitch holes and swing arm top-link. But it runs on beams untill about a third of the lengh of the machine and then runs on wheels the back to ease pulling as no beam around the leg. Weight can be added to the front of the moler, this and the 4 hitch holes will help to pull the tractor down for grip. Also can be used as a single leg if can't pull 2 and the transport width is 3m.
