Vee-cleat belt is fastened to the chain for worry-free operation.
Pintle chain is the backbone of the belt and provides more than 60,000 lbs. of high-tensile strength.
Drive system features the largest spur gear in the industry, heavy-duty gearcase and pinion and utilizes 4140 forged sprockets for extended life.
The optional Duo-Force insert features a 34" wide chain, providing consistent spread patterns with the main hopper's 34" wide belt-over-chain conveyor.
The fixed material divider at the end of the belt-over-chain conveyor ensure even distribution to each spinner.
Removable hillside baffles at the end of the belt-over-chain conveyor holds material in place when traveling over uneven terrain.
Dual 30” spinner assemblies feature a dished design and the most aggressive fins in the industry that produce a wider spread pattern with precision application rates.
Spinner drive features a jackshaft assembly that reduces maintenance requirements.
Spinner assemblies feature multiple pre-defined settings for quick and easy fore-and-aft adjustment. This operator-friendly design ensures that the correct setting is selected every time it is operated whether you're spreading fertilizer or spreading compost.
Available with 710, 580 or 450 cubic-foot hopper which are among the largest in the fertilizer spreader industry.
Raven ISOBUS rate controller allows the operator to use the tractor’s virtual terminal screen.
An on/off master foot switch is used in conjunction with the ISOBUS rate control system.
Features a single axle and category 4 Bull-Pull hitch that accommodates 2” and 1.5” hitch pins.
