Tractor tyre ka size kaise parhein

Size tyre ki side par likha hota hai. 18.4-30 mein pehla number tyre ki chaurai inch mein hai aur doosra rim ka qutar inch mein. Kuch companiyan yahi tyre 18.4/15-30 likhti hain, jis mein chaurai ka purana code shamil hai: 18.4-30 aur 18.4/15-30 ek hi tyre hain, isi tarah 12.4-28 aur 12.4/11-28 bhi.

Metric sizes jaise 12.0/75-18, jo combine harvester par aam hain, pehle chaurai, phir side ki unchai chaurai ke feesad mein, aur phir rim batate hain. Dash ki jagah R (jaise 23.1R30) ka matlab radial tyre hai.

Front aur rear tyre ka kaam alag hai

Two-wheel-drive tractor ke chhote front tyres (6.00-16, 7.50-16) sirf steering karte hain, is liye un par rib hoti hain jo side par phisalne se rokti hain. Bare rear tyres (12.4-28 se 18.4-30 tak) tractor ko kheenchte hain aur un par grip ke liye gehre tirchhe lug hote hain. Four-wheel-drive tractor jaise MF 385 4WD ke front tyres bhi lug wale hote hain (12.4-24).

Combine harvester mein ulta hai: bare drive tyres aage, header ke neeche hote hain aur chhote steering tyres peeche.

Ply rating: apne kaam ke mutabiq chunein

Ply rating (6, 8, 12, 14 ply…) batati hai ke tyre ka dhaancha kitna mazboot hai aur woh kitna wazan utha sakta hai. Zyada ply wala tyre zyada wazan uthata hai aur katne se bachta hai, jo sarak par bhari trolley aur bhatte ke kaam ke liye behtar hai. Kam ply wala tyre zyada lachakdar hota hai, khet mein behtar grip deta hai aur sasta hota hai.

  • Khet ka kaam aur halki dhulai: tractor company ki lagai hui aam ply amooman kaafi hai.
  • Sarak par bhari trolley ka kaam: usi size mein zyada ply wala tyre lein.
  • Ek axle ke dono pahiyon par ek hi size lagayein, aur behtar hai ke model aur ply bhi ek ho.

Tyres ki umar kaise barhayein

  • Rear tyre sahi rukh par lagayein: upar se dekhein to lug ka V aage ki taraf ho, taake us ki nok pehle zameen ko chhuye.
  • Hawa utni rakhein jitni tractor ki manual mein likhi hai. Hamari tafseelat mein zyada se zyada pressure ek had hai, chalane ka pressure nahi. Kam hawa se side phat-ti hai, zyada hawa se grip kam hoti hai aur darmiyan se tyre jald ghista hai.
  • Sarak par tez chalane se lug khet ke kaam se kahin jald ghiste hain. Sakht zameen par pahiye na ghumayein.
  • Diesel, tel aur khaad saaf kar dein aur jahan mumkin ho tractor ko tez dhoop se bacha kar khara karein: yeh sab rubber ko kharab karte hain.
  • Tyre us waqt badlein jab lug neeche tak ghis jayein, ya side par gehre cut, daraarein ya ubhaar hon. Naye tyre ke saath usi size ki nayi tube lagayein.
