Model 4400 - Onion Topper Loader


The Top Air TL 4400 XT is the newest member of the topper loader series of onion harvesters. This model picks up, tops and loads four 40' to 44' beds of onions, resulting in extremely high field efficiency. Like all Top Air harvesters, simplicity, durability, low maintenance and high capacity are designed into the TL 4400 XT. The extra tall profile of this harvester virtually eliminates bruising caused by rollback on the discharge elevator and makes loading today's tall trucks a breeze. The enhanced hydraulic system, which includes a larger pump, larger oil reservoir, larger hoses and larger motors, makes this our highest capacity harvester.
