Heavy Duty pivoting draw bar which is adjustable along with a HD coupler eye pintle hitch hook up made of special steel with no welds. This is especially developed and produced by Veenhuis, and includes a manual hand pump with a single acting hydraulic jack stand. Mechanically adjusted draw bar with rubber pillow block suspension for a smoother ride allows for different tractor draw bar heights. (3 different height settings) Nylon bushings in main axle pivot are easy to replace by unbolting the retainer. A central lubrication bank makes servicing the tandem walking axle easier.

Veenhuis-engineered double beamed tandem walking axle with eccentric placed centre pivot axle allows having 54% total weight on the rear axles and 46% total weight on the front tires. As a result this style of axle will take less power to pull through wet gravel, mud, sand and other difficult field conditions than any design on the market. Torgin pipe incorporated into main frame prevents twisting of main frame when dumping. Hydraulic brakes on all four wheels with slack adjuster brake arms.

Options & Features

Hydraulic forced steering makes the trailer more stable going around corners,
and for overall manoevrability versus a spring axle undercarriage. Hydraulic
forced steering also helps to make the trailer pull easier and safer to operate
both on and off the road, which in turn results in less wear on the tires and
twisting of frame components etc.. This ultimately helps to improve fuel
efficiencies. Hydraulic forced steering forces the rear axle to steer when
backing up.
Sidewall extensions with a quick lock system. This allows you to increase the box dimensions 30cm (11.8 in.), 50cm (19.7 in.), 60cm(23.6in.) H x W x L and easily allows you to haul more light material. As well, they can be universally outfitted.
