The Z90 can be used for tractors with up to a 90 HP maximum power range. Spading machines are known for solving deep soil processing problems in conditions that would be prohibitive for other tools. These machines eliminate bottom soil hardpan (deep layer of compacted soil), thus improving the deep circulation of water and aeration of the soil. Since these machines do not require any traction efforts, they can be used without issue in wet ground conditions and on sloping ground. They also reduce erosion by keeping the size of the clods at a medium level. The Z90 is a highly reliable machine, tested in the most difficult conditions by experienced and demanding users. A complete oil bath is used for crank gear lubrication, guaranteeing long life of the bearings and avoiding tedious daily greasing operations. The sides of the machines and safety devices have been completely redesigned to improve the flow of soil during operation and limit the risk of clogging. The maximum working depth is about 35 cm.
* All standard machines are supplied with low position PTO gearboxes (to fit tractors with PTO heights up to 65 cm)
** All standard machines supplied with high position PTO gearboxes (to fit tractors with PTO heights between 65 and 85 cm)
