Just noticed 2 coolant leaks, one right at the top radiator neck/hose area and one on bottom of motor where a rubber line connects to a hard line. Both have hose clamps and seem to be tight, tried tightning a little with no difference, anyone seen this? Also when going up my drive way I run in second gear, when putting a load on tractor it will pop out of gear into neutral, not every time but frequently, any thoughts on this ? It is about a1 1/2 years old with 100 hrs, what does the warranty cover?
