Case IH LB436 HD large sqaure baler

The new Case IH LB436 HD baler was shown publicly for the first time last week at Agritechnica in Hanover. The new flagship high density 120cm x 90cm baler boasts a number of new and upgraded features which Case IH claims account for a 22% increase in the density of bales over the LB434 XL model baler that remains in the range.

Starting at the front, the new LB436 HD features a new main gearbox and mid-ship gearbox with overload protection. This gearbox system eases the start-up procedure of the 400kg flywheel, which starts up in two stages – firstly from 0-684rpm and then from here up to 1,224rpm. Through Isobus, the baler then tells the tractor to engage full speed to 1,000rpm, raising the speed of the baler’s flywheel to a maximum of 1,445rpm. This system helps reduce initial load on the tractor during start-up.

The 2.35m pickup now has five tine bars fitted with 5.5mm tines. Plastic pickup bands are fitted for a smoother inflow of crop, according to the firm. A mechanically driven top assist roller spans the width of the pickup also for better crop flow.

The LB436 HD is fitted as standard with Case IH’s Rotor Cutter 29-knife chopping system. The plunger has a maximum speed of 48 strokes/min and packs a force of 62t. The longer plunger stroke compared to the LB434 XL allows for 150% more force. A longer compression channel and seven compression cylinder all add to the increased bale density.

The new Twine Pro knotter is a particular feature that sets the baler apart. The new system not only reduces twine offcuts but provides an increase in tensile strength of the knot, meaning less twine breakages.

No offcuts are formed, which over the course of 10,000 bales eliminates 3,000m of twine going to waste, the firm says.
