Grino can be aggregated typically with tractors on a tractor’s 3-point linkage of Cat. I or II (Cat. II / Cat. II). Flail shaft is powered by tractor’s PTO shaft, while the shift by tractor’s hydraulics. Mower can be mounted both at tractor’s rear and front, which improves general comfort of operation. Mower is additionally equipped with transverse shift option to provide easier passing of obstacles and adjusting the most comfortable turning.
Use
- Mowing shrubs and bushes, shredding branches of max. diameter of 5 cm
- Cutting weeds and grass on uncultivated areas, treatment of sterile pastures and operation on green areas (orchards, vineyards)
Advantages:
- Drive transmission by belt gear functions as overload clutch
- In order to prepare mower for operation at tractor’s front, re-mount upper holder at mower’s opposite side and re-install it at PTO shaft’s opposite side. If tractor features left-hand rears, these can be user-changed by dismounting central gear and turning it around by 180°
- Mower is hydraulically adjustable in relation to either tractor’s left or right side. Features standard-mounted hydraulic cylinder
- New stronger housing has been designed to provide effective protection of bearings against dirt, while extending mower’s lifespan
- Properly adjusted flail’s weight (0.7kg) and precise mounting and arrangement of bolts on shaft provide mower’s effective operation in difficult conditions
- Large diameter of flail shaft (ϕ 168 mm) improves its stiffness and peripheral speed of knives
- Mounting on 3-point linkage at tractor’s front or rear
- Simple replacement of flail knives
- Silent operation of flail shaft
- Perfect fitting to ground and optimal mowing height
- Top-quality metal sheet guards at mower’s front and rubber guard at mower’s rear provide effective protection against thrown out stones
- Standard-delivered PTO shaft
- Adjustment of mowing height within range of 3 and 8 cm with use of ground following bar
- Strengthened enclosure and enhanced bearings of flail shaft
- Easily replaceable skids made of durable steel
- Additional internal and side strengthening of enclosure made of hard and durable steel
- Standard-delivered overrunning clutch in intersecting axis gear
- Innovative solution for protection of bearings and their lubrication
- Cross traverse by 50 cm possible
