I’m going to have a go towing it to hopefully free it up. So my questions are. 1 should I do short bursts are tow it for 500 m. 2 should the pro be in neutral or engaged or doesn’t matter 3 should I crack an injector to stop it starting as it doesn’t have a pull stop lever and 4 should I spray som Unix in the inspection plate under the fuel filter. The tractor has been sitting for 6 months and was fine before that. Thanks in advance
