Trouble-free John Deere engine drives massive new grain conveyor

The John Deere 6068T1 engine provides all the power this OZTech Grain auger needs

An enormous new tube conveyor for shifting grain designed and built by Queensland industrial engineers Oztec easily gets all the power it needs from a John Deere 6068T1 industrial engine.

Oztec manufactures grain and cotton-handling equipment for the agricultural sector, as well as industrial conveyors and other equipment for the oil and gas drilling and mining industries.

The Oztec range of grain augers and Tubeveyors come in a variety of lengths, diameters and engine sizes to suit any farming operation.

The new 40m Tubeveyor is the largest conveyor of its type the Toowoomba-based company has ever built.

Oztec Managing Director John Sheehan says his team designed and built the Tubeveyor for a farmer with specific requirements. It is a 600 mm-wide belt conveyor inside a 1200 mm tube and has the capacity to carry a wide range of grains.

“We have been building self-propelled augers and tube conveyors since we started in 2003, but this is the biggest one we have ever done,” he says.

“It is run by a John Deere 6068T1 industrial engine, which is the same engine we have put in our earlier models. It is a very reliable engine and has more than enough power for this job as well. Over the last 15 years we haven’t had one bit of trouble with these engines.”

John says the Tubeveyor is unique in its size.

“With a belt conveyor like this you can only run it up to an angle of 25 degrees or the grain starts falling backwards on the belt. It is 40m long to get the height needed to fill silos that are 15m high.

“We could have built it as a shorter self-propelled grain auger, but over that height an auger puts a lot of pressure on the grain. The belt is a lot softer on lupins and chickpeas, so it handles the grain more gently. That’s the main reason this farmer went with the belt conveyor this long.”

Oztec came up with a completely new design for the 40m Tubeveyor to give it a high level of stability. It features four wheels on 6m wheel centres.

John Deere’s 6068T1 is a six-cylinder engine providing nett continuous at 144 hp. It runs at 1800 rpm, which means it is not working excessively hard for this application.

The 6068T1 features a dynamically balanced crankshaft, forged-steel connecting rods for increased durability, a self-adjusting Poly-vee fan drive that can be matched to specific application requirements, and replaceable wet-type cylinder liners that provide excellent heat dissipation.

The 6068T1 provides an optional gear auxiliary drive which produces up to 50 hp for gear-driven accessories, while standard front-and-side mounting points provide easy installation and application flexibility.

“The engine is working well,” John says. “We have put a Kensho K27 engine controller with it, which is a computer that provides the engine with greater protection and management.

“It is very easy to operate and has a lot of features which we don’t need to use, but it has very extensive software in it and it goes well with the John Deere product.”

Oztec is looking forward to further developing its relationship with Power Equipment, since the company took over the Australian and New Zealand distribution of John Deere industrial and marine engines.

“John Deere is a well-known name and that’s an advantage for us. Farmers are confident they know what they are getting and when they need parts or service, there are agents or dealers all across the country,” John says.
