Please redesign the ability to change the oil and filter. I had dealer place a hose and quick drain valve and this was worst than the drain plug. What a mess!! I could not get to the filter. Remember to use synthetic oil with high zinc content 15-50W in south. The belts slipped off on first use was not properly tightened/tension I love the mower except the oil change problem. Do I need to change tranaxel Fluid??
