Hi i recentley posted a message on my tractors brakes as i am only 16 and have just brought my first tractor (zetor 7045) i havevery little nollege on the girl, so i have a few questions to ask you zetor fans. 1. where can i find the hydrolic oil fill hole as i cannot find it anywhere on my machine. 2. i was pulling a trailer today and now the clutch makes almost a grinding noise when i pull it out half way but yet still works fine. and finally as my tractor only has 1 sprool valve fitted to it i would like to get an extrra so i can operate a trailer brake on the sprool and also a tipper at the same time and i did not know wether to get a single acting sprool or double acting any1 have some ideas. Thanks in advance
