I have a new (less than 12 hours) Lazer HP (52" w/ 23 Kawi) that seems to have a possible hydro related problem. After cutting for about an hour, I start to lose power in the right side and fluid begins to leak out of the reservoir cap. If I put the right side into reverse, I get little to no movement unless I coax it by putting the left into reverse a bit. Going forward, I need to push the right side lever much farther forward than the left in order to track straight, and I end up going much more slowly. Again, this occurs only after it is hot, about an hour or so into the cut. The dealer looked at it and thought there might be in air in the hydro and serviced it, but problem re-occurred immediately. In addition, wouldn't air in the system affect both sides and not just the right? I am only cutting my own lawn with the machine (about 3 acres) and it has very low hours, so I am wondering if it is possible that the right side hydro is defective? It is currently in the shop, but I think that they are a bit perplexed about the problem. (It only occurs after about an hour or so of use, and only in the right side.) Any insight you have would be really useful. Thanks!
