6. Wheel hoe
• It is used for weeding and inter-culture in row crops. It is a long
handled tools operated by push and pull action. The handle
assembly as a provision to adjust the height of the handle to suit
the operator. Working depth of the tool can be adjusted with the
help of clamp or through the plate with multiple holes provided
in the frame and welded to the tool assembly.
Field capacity of single
tyne hoe was 0.02 ha/h.
Working depth (mm) of
wheel hoe was 0-60 mm.
The highest field capacity
was observed in wheel hoe
among the three manual
weeder wheel hoe,
crescent hoe and kasola.

7. • Manual Seed Cum Fertilizer Dibbler (Stainless steel
dibbler can drop the fertilizer and seed upto 2-3 inches
deep within the surface of the soil. Length, diameter
and opening of dibbler was 32, 1.5 and 1 inch
respectively. Working speed was 35 seeds/minute.
(MK Krishi yantra)
• Naveen dibbler consisted of jaw type seed
placement device, cell type metering mechanism,
lever type power transmission system for metering
and jaws opening. It can sow the bold seed like
maize, soybean, sorghum etc.
• Dibbler should keep at angle of 20 0C with vertical
during sowing.
• Field capacity of Naveen dibbler was 0.25 ha/day or
300- 400 hills/h and depth of operation was 35 mm.

8. • Manual seed cum fertilizer dibbler dibbler

rajma etc)
• Hoper seed and fertilizer capacity 5 Kg. it can sow
the 1-3 Seeds or 0.8000-1 ha/days
• Rotary dibbler consisted of rotating dibbling head
with penetrating jaws, covering cum transport
wheel, seed hopper with cell type metering roller
and handle. Number of jaws varies from 5 to 8
depending upon the seed distance.
• The seed to seed distance depends upon size of
polygon plate to which jaws are attached.
• Depth of seed placement, field capacity were 20
mm and 0.34 ha/day.

9. Two row vegetable transplanter
• Two row vegetable transplanter was
developed for transplanting of plug type
vegetable seedlings on ridges and mulch
beds.
• It consisted of frame, seedling tray holder,
hand lever, frame support rod, jaw
assembly, seedling feeding pipe, handle,
gauge wire, marker holder and marker
• The transplanting rate of vegetable seedlings using single labour
was found to be 8, 5 and 23, 17 seedlings/min for Manual
transplanting on ridges, plastic and manually operated developed
transplanter on ridges, plastic mulch beds respectively. Forward
speed was 0.2-0.4 km/h and average seeding was10-20/min.
(Nandede et al 2017)

10. • Direct paddy seeder is made up of plastic material.
• Diameter of wheel, seed drum diameter, seed requirement, machine
weight are 60 cm, 20 cm, 10 kg/acre and 10 kg respectively. There
are 8 number of seeding metering holes of 9 mm hole diameter.
Each seed drum has two rows of planting
• Baffles are provided inside the seed drum between the seed holes to
ensure the uniform seed rate in operation
• Water should be drained out at least 24 h before sowing to form
hard slurry pan of the puddle soil. At the time of sowing only paper
thin of water should be maintained in the puddle field.
• Only just sprouted seeds should be used.
• Water should be flooded to the puddle
field once in 3 days after sowing and drain
out immediately. This practice should
continue for 12 days
• Pull the seeder at speed of 1 Km/h
• 8 rows of 20 cm row to row
• Field capacity was 1 hectare per day

11. • Manual Groundnut Decorticator is a
simple rocking type machine for crushing
groundnut pods to separate the kernels.
• Drudgery reduction by 79% per unit of
output.
• It consists of a steel frame, arch-shaped perforated grate and three
cast iron peg-type crushing shoes attached to an oscillating arm. Its
capacity is 35 kg/h
• Tubular Maize Sheller is used for separating
maize from pod. It separation capacity is 13.5
– 16.9 kg/h, which was about 2-times more
than traditional method.

12. 7HP mini tiller
• This tiller is used for tillage, inter
cultivating, turning the soil, weeding,
aerating and making rows for plantation.
• 7HP mini tiller very useful for small level
farmers.
• It is 4 stroke, 3600 engine RPM, 212 CC Petrol Engine. It is
manually started engine. Fuel Tank Capacity, Cutting Width,
Cutting Depth, Gear Shifting, Fuel Consumption and Weight are
3.6 L, 36-42 inches (adjustable), 6-12 inches, (-1,0,1,2), 600
ml/hour, : 105 Kg respectably.
• Tiller Price is approximately Rs.44000.
• This engine come with different attachment like, cultivator,
different size of rotavator, MB plough, Trailer, sprayer, puddling
rotor and wheel (it may provided by Whatpp- 9815940212) and also
provided by other seller.

15. Brush Cutter
• 4 Stroke Petrol engine
• 1.6 hp
• Fuel Tank Capacity – 0.6 l
• Fuel consumption: 0.7 l/h
• Rs. 14300/ amazon

16. Manually operated gladiolus planter
• Manually operated planter was developed at
PAU, Ludhiana for planting gladiolus corns.
The cup feed type metering unit picked the
gladiolus corm individually into the cups and
delivered it into seed pipe. The picking spoon
of diameter 50 mm and depth 22 mm was
fabricated for evaluation. A circular PVC pipe
of 76.2 mm diameter was attached to the
bottom end of the funnel to conduct the corms
to the furrows. The maximum picking of
single of 72.46 and 73.2% was observed for
corm Grade I at forward speed of 1.5 km/h
and 2.0 km/h

17. Pedal operated paddy thresher
• It consists of wire-loop type
threshing cylinder of 400
diameter x 600 length.
• Loop wire diameter is 4 mm and
Number of wire loop strips 10-
12. No. of wire loops/slat 8-9 .
• Pedal Crank mechanism with 1:4 gear ratio
• The pedal thresher was found 50-70 % more efficient than
manual threshing
• The output capacity of the thresher was 39 kg/h as against 31
kg/h in manual beating of paddy. It was observed that there
was 20% increase in output with paddy thresher
