Hello all, I recently purchased a used Mahindra 5155, and have been enjoying it so far, but I have noticed when driving on the road in high 4, AKA top gear, that the tractor can bog down on a small incline. I already drained the fuel tank and checked the fuel filter and air filters. The pre-filter is a little bit dirty and the fuel filter had a decent amount of sediment when I drained it, so I'm going to replace those and try it again. I'm just not sure if this is normal for this tractor in high gear or if there's actually something wrong. Does anyone else have a 5145 or 5155 that can shed some light? TIA
