Lettuce rows that need finer weed control
This product suits lettuce blocks where row spacing is tight and the crop canopy leaves little room for a broad spray pass. The system uses camera-guided weed detection to read the bed, then directs laser energy at weed growing points while the tractor moves through the field.
It is a practical fit for open field lettuce, rotated blocks, and farms that want another control option where hand weeding has become heavy. Field speed changes with weed pressure, weed size and ground conditions, so the pass plan needs to match the block rather than a fixed pace.
- Tractor-drawn laser weeding unit for lettuce beds
- Camera-guided detection for weed spotting in-row and between rows
- Laser targeting at weed growing points
- Useful where crop spacing and weed timing both need care
Bed widths, row gaps and the option set
Lettuce Bed Hire is arranged around the block layout, not a one-size setup. The working width, row count and tractor match are set against the bed spacing, turnaround room and crop stage on the day.
Most lettuce work needs a narrow, controlled pass with enough clearance to protect the crop while the laser head reads the weeds. Taller or denser weed pressure can slow the pass rate, and very young weeds are usually easier to target than older, tougher growth.
- Best for single and multi-row lettuce beds
- Working width set to the field layout
- Tractor drawbar match needed for the unit
- Operator supplied with the hire
- Repeat pass planning available where pressure builds through the season
Where lettuce laser work fits best on the farm
It suits farms that want herbicide-free weed control on lettuce without turning the soil between rows. Because the system is tractor-drawn and the treatment is directed, the crop surface is not cut up by cultivators or hand tools across the whole bed.
That makes it useful where rows are clean but the gaps still carry flushes after irrigation, rain or warm spell conditions. On Cape Town coastal ground, morning moisture and softer soils can change the run pattern, so arrival site checks and field timing matter before the unit goes in.
- Open field lettuce blocks
- Blocks with repeated flushes after irrigation
- Areas where soil disturbance must stay low
- Growers needing a season plan rather than one-off weed control
Fitting the unit to the block on arrival
The unit needs a suitable tractor, level working ground and enough access for turns at the headlands. Setup includes hitching, alignment to the rows, camera calibration and a short field check before the pass begins.
For lettuce, row line discipline matters. If the bed is off line, the operator has to slow the run and spend more time on positioning. Our team also checks canopy height, weed stage and whether the block is ready for a trial strip run before the full pass is planned.
- Tractor-drawn setup and operator supplied
- Alignment to row spacing before the pass
- Camera calibration for the crop pattern
- Trial strip runs available on mixed blocks
Keeping the unit ready between passes
Laser weeding gear needs routine care to hold alignment and keep the lenses, sensors and moving parts clean. Dust from dry inland blocks, damp coastal mornings and crop residue can all affect how the system reads the row.
After each block, the unit should be checked for dust build-up, loose fittings and any debris around the working heads. Where a grower wants repeat pass planning, the field notes help set the next run against weed stage rather than guessing at a date.
- Keep lenses and sensors clean
- Check hitches, guards and cable runs
- Remove dust and residue after field work
- Use post pass reporting to track the next visit
What to confirm before a lettuce booking
Before the booking is set, we need the lettuce variety, block size, row spacing, tractor access and the weed pressure in each section. It also helps to know whether the block is in Philippi, Ceres, Grabouw, Tzaneen, Bela-Bela, Nelspruit, Howick or Bethlehem, because travel planning changes the schedule.
For multi farm programmes, growers often group lettuce with other row crops in the same season booking. That can include field assessments, crop timing plans, operator supplied work and travel coordination for more than one site.
- Crop type and lettuce growth stage
- Row spacing and bed width
- Block size and field access for the tractor
- Weed stage and recent irrigation or rain
- Season booking needs across one or more farms
