Crendon Machinery have made a new design Sadie with 50% more nylon bristles, each bristle is twice the diameter as before. Now comes with spring tynes for heavy sweeping out of grass.
Orchard SADIE is a pruning and leaf sweeper which clears prunings and debris from under fruit trees and vines, improving vineyard hygiene. The steel spring tynes easily removes weed clumps to give clean ground for pre-emergence herbicide spraying.
The SADIE now comes with Steel Spring Tyne, nylon bristles and rubber flaps as standard.
SADIE eliminates the need for hand raking and has proven to be important in the control of Black Spot.
SADIE's long nylon bristles do not damage tree trunks or trickle lines. A replaceable skid is incorporated into the bottom of the rotating head to assist in height control.
SADIE's spinning head has a shear bolt system mounted immediately after the hydraulic ram, which allows the head to swing back 120º preventing further damage to the unit.
A heavy duty deflector, mounted in front of the SADIE prevents debris being thrown too far. If this deflector hits a solid object, while turning at the end of rows, a shear bolt breaks and prevents any damage.
The Orchard SADIE now comes complete with a steel mesh guard to protect tractor from flying debris. Also comes with a heavy duty deflector which fits beneath the SADIE's mesh guard protecting the bottom of the tractor. Both guards are bolt-on and have adjustable over-hang settings.
SADIE’s clean sweep reduces the amount of herbicide required to maintain weed free strips
The driver has a clear view and can easily manoeuvre the SADIE. SADIE is mounted onto the tractor's front bumper bar for best visibility and driver control. One hydraulic ram raises and lowers both the arm and angles the head, a hydraulic flow control valve regulates the head spinning speed.
Orchard Sadie with rubber flaps rear view
Rubber flaps were developed in 2001 and have been further refined for the new 2020 model. The new flaps are longer with a more tapered shape giving a softer sweep for the first 50mm (similar to nylon bristles).
Rubber flaps are recommended for use providing there are no trickle lines on the ground. They do not cause damage to vine stems or tree trunks and height setting is not critical. The advantage of rubber flaps is that they have a very long life.
SADIE leaves a neat windrow of pruning and a clean strip beneath the trees ready for herbicide spraying.
Usually the tractor is fitted with a mulcher or mower on it's 3 PL so that sweeping and mulching of prunings occurs at the same time.
