\n \"EW-4000
\n <\/figure>\n

<\/p>\n

\n The EW-4000 is a heavy-duty rock rake \u2014 1,800 kg, 100 cv, 3.6 m working width, steel tine system handling rocks to 300 mm diameter, 3\u20135 km\/h, 60 L\/min minimum hydraulic flow, 2 control valves, Cat 2 linkage, 2-year gearbox warranty. It rakes surface and near-surface stones from agricultural fields, construction sites, and cleared land into windrows for collection \u2014 with minimal soil disturbance, preserving topsoil structure for subsequent planting or construction operations.\n <\/p>\n

<\/p>\n

Who the EW-4000 Is For<\/h2>\n

The EW-4000 suits large commercial farms, land developers, and construction contractors where the priority is clearing surface stones across wide areas with minimum soil disruption. At 3.6 m working width and 100 cv minimum, it covers large field and site areas efficiently from a standard commercial tractor \u2014 making it practical for farms in Punjab, Haryana, and Maharashtra running stone clearance ahead of planting, and for construction and infrastructure projects clearing land before base preparation.<\/p>\n

For operations where stones must be picked up and removed from the field entirely rather than windrowed, the CT-2100 \u5ca9\u77f3\u62fe\u53d6\u5668<\/a> (3,400 kg, 110 cv, 2.5 m\u00b3 onboard bunker) collects and holds stones for direct haulage \u2014 the EW-4000 and CT-2100 work as a sequence or independently depending on site logistics and dump-point access.<\/p>\n

On sites where a loader or tractor with front bucket is available to collect windrows, the EW-4000 covers more area per hour than the CT-2100 at its wider working width. Where no loader is available, the CT-2100’s self-contained bunker and dump cycle removes stones without a secondary collection machine on site.<\/p>\n

<\/p>\n

How the EW-4000 Works<\/h2>\n
\n
\n
TINES<\/div>\n
\n
Steel Tine System \u2014 3.6 m Width, Rocks to 300 mm<\/div>\n

The tine arms pass through the soil surface across the full 3.6 m working width at 3\u20135 km\/h \u2014 lifting and pushing stones forward into a windrow while allowing fine soil to fall back through the tine gaps. The tine geometry is set to engage rocks up to 300 mm diameter without stalling or tine deflection, and to pass over the surface with minimal disturbance to the soil structure below.<\/p>\n<\/div><\/div>\n

\n
HYDRAULIC<\/div>\n
\n
Fully Adjustable Hydraulic System \u2014 Depth and Angle<\/div>\n

The hydraulic system controls tine depth and rake angle from the tractor cab \u2014 adjustable to suit different soil types and stone concentrations. On soft alluvial soils in Punjab, shallower tine engagement preserves the topsoil layer. On harder laterite or basalt in Maharashtra and Karnataka, deeper engagement ensures stones embedded just below the surface are lifted and raked rather than pushed past. The 60 L\/min minimum flow requirement ensures consistent hydraulic response throughout the raking pass.<\/p>\n<\/div><\/div>\n

\n
WINDROW<\/div>\n
\n
Windrow Formation \u2014 Collection by Loader or Picker<\/div>\n

The EW-4000 rakes stones into windrows at the end of each pass \u2014 or along one edge of the field, depending on the operating pattern. Windrows are then collected by a front loader, tractor bucket, or the CT-2100 Rock Picker running a collection pass on the windrow line. This two-machine sequence is common on large sites where a dedicated loader is already on site for other operations.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n

Applications<\/h2>\n
\n \"EW-4000
\n <\/figure>\n
\n
\n
Primary Use<\/div>\n
Large-Area Field Clearance \u2014 Pre-Planting<\/div>\n

Clearing surface and near-surface stones across large agricultural fields before planting \u2014 the 3.6 m working width covers wide field areas faster than narrower alternatives, making it practical for the annual pre-season clearance programs on large Punjab, Haryana, and Maharashtra farms where frost heave, tillage, and rainfall continuously bring new stones to the surface each season.<\/p>\n<\/p><\/div>\n

\n
Construction Sites<\/div>\n
Debris & Rock Clearance \u2014 Pre-Base Preparation<\/div>\n

Clearing rocky debris and construction waste from land ahead of base material placement \u2014 industrial parks, residential developments, solar project sites, and road construction right-of-ways where the surface requires clearing before grading and compaction begin. The EW-4000’s minimal soil disturbance characteristic preserves the sub-grade level established by the prior grading pass.<\/p>\n<\/p><\/div>\n

\n
Vineyard & Orchard<\/div>\n
Rocky Inter-Row Clearance \u2014 High-Value Crops<\/div>\n

Clearing inter-row stone accumulations in vineyards and orchards in Maharashtra, Karnataka, and Tamil Nadu \u2014 where stones damage undercutting and mowing equipment, impede harvest machinery access, and reduce the effective working depth of inter-row cultivation. The EW-4000’s adjustable tine depth allows the operator to work at the correct engagement for each inter-row profile without disturbing the root zone.<\/p>\n<\/p><\/div>\n

\n
Post-Crusher Cleanup<\/div>\n
Surface Clearing After Stone Crusher Pass<\/div>\n

After a THOR stone crusher pass on rocky land, some larger un-crushed fragments and surface debris remain. The EW-4000 rakes these into windrows for final removal \u2014 completing the surface to a clean, workable state before rotavation or base compaction begins. It works as the final cleanup tool in a CT-2100 rock picker \u2192 THOR stone crusher \u2192 EW-4000 rake \u2192 rotavator sequence on heavily stony land reclamation projects.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

Before You Order<\/h2>\n
\n\n\n\n\n\n\n\n\n\n
Question<\/th>\nWhy It Matters<\/th>\n<\/tr>\n<\/thead>\n
Tractor HP \u2014 100 cv confirmed?<\/td>\n100 cv minimum. The hydraulic system and tine arm mechanism require adequate power for continuous operation across the 3.6 m width at 3\u20135 km\/h.<\/td>\n<\/tr>\n
Hydraulic oil flow \u2014 60 L\/min?<\/td>\n60 L\/min is the minimum flow for consistent hydraulic depth adjustment and tine angle control. Confirm your tractor’s rear hydraulic pump output \u2014 not just system pressure \u2014 before ordering.<\/td>\n<\/tr>\n
2 rear SCVs available?<\/td>\nThe EW-4000 requires 2 hydraulic control valves for depth and angle adjustment. Confirm both SCVs are active and unoccupied on your tractor.<\/td>\n<\/tr>\n
Windrow collection \u2014 loader available?<\/td>\nThe EW-4000 rakes stones into windrows \u2014 it does not collect them. A front loader, tractor bucket, or the CT-2100 Rock Picker is required to collect and remove the windrows from the field. Confirm your collection plan before ordering.<\/td>\n<\/tr>\n
Rock size on site \u2014 above 300 mm?<\/td>\nThe EW-4000 handles rocks to 300 mm. Stones significantly above 300 mm require manual pre-clearing or a stone crusher pass before the rake can operate without tine damage or jamming.<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n
