Özet:

 In the study conducted on the data obtained from the hydraulic lifting force HL tests carried out at the Agricultural Tools and Machinery Test Center Directorate TAMTEST according to OECD Code 2 tractor performance test standards; The effect of hydraulic lifting force capacities of tractors on overturn backwards rearing was tested. As it is known, in HK tests, one of the OECD Code2 tractor performance tests, tractors are fixed to the ground by a chain from their front axles before loading. The measures taken for safety purposes cause the tested tractors to not fully reflect the HK performance of the tractors in field conditions and the rearing effect to be ignored. In the study; The height of the lower link arm pivot point of the tractors from the ground was accepted as the reference point and called the parallel point. In addition, the distances between the lower link arm pivot point and the axles of each tested tractor were measured, the dynamic load falling on the front axle at the parallel point, at maximum loading, was found by simple moment calculation, and it was calculated whether the tractors reached the rearing point. The test data of a total of 262 tractors were tested and it was calculated that 104 of the tested tractors reached the rearing point.

 OECD Kod 2 traktör performans test standartlarına göre, Tarım Alet ve Makine Test Merkezi Müdürlüğünde TAMTEST gerçekleştirilen hidrolik kaldırma kuvveti HK testlerinden elde edilen veriler üzerinde yapılan çalışmada; traktörlerin HK kapasitelerinin, geriye devrilme şahlanma üzerindeki etkisi incelenmiştir. Bilindiği üzere OECD Kod2 traktör performans testlerinden biri olan HK testlerinde traktörler yükleme öncesinde ön akslarından zincirle yere sabitlenmektedir. Güvenlik amacıyla alınan önlemler, test edilen traktörlerin tarla koşullarındaki HK performansını tam olarak yansıtmamasına ve şahlanma etkisinin göz ardı edilmesine neden olmaktadır. Yapılan çalışmada; traktörlerin alt bağlantı kolu oynak noktasının yerden yüksekliği referans nokta kabul edilmiş ve paralel nokta olarak adlandırılmıştır. Ayrıca test edilen her bir traktörün alt bağlantı kolu oynak noktası ile dingiller arası mesafeleri ölçülmüş, basit moment hesabıyla paralel noktasında, azami yüklemede, ön dingile düşen dinamik yük bulunmuş ve traktörlerin şahlanma noktasına ulaşıp ulaşmadığı hesaplanmıştır. Toplam 262 traktörün deney verileri incelenmiş olup, test edilen traktörlerin 104ünün şahlanma noktasına ulaştığı yapılan hesapla bulunmuştur.
