Larger silage wagon launched

Written by 

EXTRA LARGE: key words for Robertson Manufacturing Ltd’s latest Mega Comby silage wagon XL (extra large). It was launched at the South Island Field Days.

 

Said company principal Don Robertson, “This machine will feed out everything normally fed by larger farmers to stock in feed lots and in paddocks.” It holds 24m3 – 12 large square bales and up to 12t of grass or maize silage.

“Our new feed pad dispensing elevator is our biggest and best design change we have made,” Robertson says.

Previously when dispensing to feed lot bins two delivery conveyors were used with the cross conveyor loading on to the elevator taking feed to the bins. 

Feed was lost when the cross floor conveyor slats lodged material under the wagon as it returned, dropping it on the ground. In the paddock this was still eaten by the stock but in a feed lot it was wasted.

“We are talking perfection here as the amount dropped in the feed pads was miniscule,” Robertson says.

With the new feed pad kit (see diagram) the elevator to the bins extends well under the cross floor conveyor so collects all the material lodged in the slats as the conveyor rotates. The elevator can be raised hydraulically from horizontal to vertical for travelling and anywhere in between to deliver to bins. A safety feature is that the machine will not operate until the elevator is in the working position.

Says Robertson, “I believe this is a major advance for our machines and reduces wastage to almost nothing.”

The company prides itself on the body strength of their machines. Those with weigh cells have always been of double chassis design; now all models are of a mono structure design where chassis and body are all one, giving a truss like structure.

“The one piece structure is a lot stronger from draw bar to axle giving extra strength as opposed to our previous two piece system.”

There are now four weigh cell pods off the axle and the machine has a two cell drawbar system which can weigh the load when it is attached to the tractor or standing on a jack.  The weigh cells are optional.

The Mega Comby XL has a fully tracked double floor triplex chain with increased power from the drive box and tub sides to ensure total emptying of material. The rear door has an auto release in case the floor is accidently reversed. It has a swivel towing eye and 120hp plus is recommended.

It comes standard on tyres 405R 22.5; or flotation 550/45 22.5 are an option. Other extras are weigh cells and wireless connection to the tractor cab.
