7 EFFECTIVENESS OF SEALINGS

After completion of field test in wetland operation for 16.1 h, the implement was

dismantled for checking effectiveness of sealings provided against ingress of dust and

water/mud in various sub-assemblies and also to check the condition of components of the

rotavator.

Sl.No. Location Whether ingress of mud

and/or water was observed

1. Primary reduction gear box No

2. Secondary reduction gear box No

3. Rotary axle bearing cap No

8. EASE OF OPERATION & ADJUSTMENTS

The operator can easily adjust and control the implement from operator’s seat in the field as the adjustments are within the easy reach of operator. However the operator has to get

down from the tractor in order to raise/lower the depth adjusting skids.

9. DEFECTS, BREAKDOWNS AND REPAIRS

No break down was observed during 43.1 hours of dry and wet land operation

10. SUMMARY OF OBSERVATIONS, COMMENTS AND RECOMMENDATIONS

10.1 The specification of implement hitch does not conform fully to the IS: 4468 (Pt-I)-1997

(Reaffirmed in 2001). It is recommended that the same should be provided conforming

to the relevant Indian Standards.

10.2 The hardness of rotavator blades at shank & edge portion was recorded as 298 to 383 and

354 to 393, against the requirement of 37 to 45 HRC (344 – 411 HB) and 56 ± 3 HRC

(512 – 634 HB) respectively. The hardness at shank portion is considered on higher side

and at edge portion is considered on lower side than the requirements of relevant Indian

Standard. This should be looked into.

10.3 The rate of work was recorded as 0.381 to 0.414 ha/h at forward speed of 2.87 to3.02

km/h in dry operation. The wetland operation required two Passes to get desirable

puddling index.

10.4 The depth of operation in dry was recorded as 11 cm and depth of puddle was

recorded as 21 to 22 cm, which is considered normal for such Operations.

10.5 The hourly rate of wear of blades on mass basis in dry land and wet land operations were

recorded as 0.02 to 0.09 % and 0.01 to 0.03 % respectively.

10.7 The hourly average rate of wear on dimensional basis of blades in dry and wet land

operations was recorded as 0.06 to 0.14 % and 0.06 to 0.13 % respectively.

10.8 No ingress of water/mud was found in primary, secondary reduction boxes and rotary

axle bearing cap after 16.08 hours of wetland operation and the sealings provided on

different subassemblies were found effective.
