Patent Application - Sinch Bale Feeders

In Australia most times we travel to farm location and install on old highway semi trailers up to 45 feet long.

In US square bale feeder units are manufactured by Doherty Welding Pilot Rock Oregon

 
Sinch Square Bale Feeders was invented and the patent applied for in April 2006 by Gerard Kenna at the family dairy farm "Scarriff" Western Victoria Australia. The USA Patent Office issued Patent Number 8371791 on Feb 12th 2013.

The initial goal was to find a quick and cost effective means of feeding large square bales of silage. Over time he developed a safe, fast and simple way to feed out big loads of square bale silage and hay.

Since Easter 2006

Sinch Big Square Bale Feeders won first prize at Sheepvention Hamilton in August 2006 and became a finalist in the National Agricultural Inventors Awards at the Australian National Field Days at Orange New South Wales, October 2006. It was then known as The Extruder. The Extruder's name was then changed and trademarked as The Sinch Big Square Bale Trailer Feeder as the name Extruder could not be trademarked.

The Sinch Big Square Bale feeder was then officially launched at Sungold Field Days 2007 and taken to Farm World Lardner Park February 2007, The Sinch then won at The DairyVator Innovation Awards for South West Victoria 2007.

Hay Trailer - Sinch Bale Feeders

 

Research & Development

The Big Square Bale Flakers were added early in 2009 and with exhaustive research and development since 2006, these Big Square Bale square bale hay flaker feeders are taking their place as the premier square bale feeder on the world market. To give an insight into the quality of Sinch Big Square Bale Feeders, the working load capacity of the main components is much above what is needed (these have been sourced from the mining industry) and will last a very long long time. This square bale feeder has been refined and simplified to the degree that it only requires 2 hydraulic hoses and the sole control is one single lever already inside the cab or a small hand held wireless remote. Remarkably there is only one hydraulically driven gearbox.

In late 2017 Gerard visited Utah USA when Rancher Charles Redd of Redd Agri La Sal Utah showed strong interest. Gerard then discovered the numerous deck over goose neck trailers that are perfect for installation (these trailers are rare in Australia). The 24-26 trailers can have a fixed or detachable platform unit. Best of all, a key start wireless remote controll hydraulic power unit can be fitted, giving it the versality to be towed with tractor or pick up. It's just a matter of plugging the same 2 hoses into tractor hydraulic plug in remotes or hydraulic power pack.

Gerard was then fortunate to find Doherty Welding in Pilot Rock Oregon as the manufacturer of Sinch Bale Feeders in November 2019.

The hay trailers that Sinch Bale Feeders are installed on usually have load capability that enables them to be used for numerous other farm tasks including transporting loads of hay and silage. The best and most efficient tractor to tow Sinch Bale Feeders have pick up hitch.
