Thus, it was necessary to revise the existing national standards on the walking-type agricultural tractor. In response, the Agricultural Machinery Testing and Evaluation Center (AMTEC)-University of the Philippines Los Baños (UPLB) initiated the development of the standards on walking-type agricultural tractor — Specifications — Part 1 (Pull-type), Part 2 (Rotary-tilling type) and Part 3 (Float-assisted tiller) and Methods of Test. The development of these standards was made in collaboration with the Bureau of Agriculture and Fisheries Standards (BAFS)- Department of Agriculture (DA) as the mandated agency to develop Philippine National Standards (PNS) for agriculture and fisheries machinery and infrastructures. The Technical Working Group (TWG) tasked to develop the PNS was created through Special Order (SO) No. 617, series of 2022 (Amendment to Special Order No. 487, series of 2022 [Addendum to Special Order 103, series of 2022 entitled, “Creation of TWG for the Development of PNS for Agriculture and Fishery Products, Machineries, and Infrastructures”]). The TWG was composed of representatives from the relevant government agencies, academe, and research institutions. The draft PNS underwent a series of TWG meetings and stakeholder consultations via online platforms before their endorsement to the DA Secretary for approval. This PNS/BAFS edition includes the following significant changes compared to PAES 110:2001 (Agricultural machinery – Walking-type agricultural tractor – Specifications – Part 2: Rotary-tilling type): a) Inclusion of tractors with other transmission system in the “Scope”; and b) Inclusion and modification of provisions for “WTAT Parts and Components”, “Fabrication Requirements”, “Performance Requirements”, “Safety, Workmanship, and Finish”, “After-sales Requirements”, “Maintenance and Operation”, “Sampling”, “Testing”, and “Marking and Labeling”. This Standard cancels and replaces PAES 110:2001. This PNS was drafted in accordance with the BAFS-Standards Development Division (SDD) Standardization Guide No. 1: Writing the Philippine National Standards. ii PHILIPPINE NATIONAL STANDARD PNS/BAFS 346:2022 Walking-Type Agricultural Tractor — Specifications — ICS 65.060.10 Part 2: Rotary-tilling Type Table of Contents Foreword ii 1 Scope 1 2 Normative References 1 3 Terms and Definitions 2 4 WTAT Parts and Components 3 4.1 Components 3 4.2 Controls 4 5 Fabrication Requirements 5 6 Performance Requirements 6 7 Safety, Workmanship, and Finish 6 8 After-sales Requirements 7 9 Maintenance and Operation 7 10 Sampling 7 11 Testing 8 12 Marking and Labeling 8 Bibliography 9 iii PHILIPPINE NATIONAL STANDARD PNS/BAFS 346:2022 Walking-Type Agricultural Tractor — Specifications — ICS 65.060.10 Part 2: Rotary-tilling Type 1 Scope This Standard specifies the minimum requirements for Walking-Type Agricultural Tractor (WTAT) which is classified as rotary-tilling type.
