Hi, Just wondering at what % of throttle should i engage the blades on my Fastrak 52/20 unit? Is it to much for clutch to take at full RPM's ? Also, with 35 hrs on this machine...what kind of maintenence should i do? I cut 3 times this season and about 6-7 times last season. I keep my air filter and foam clean every run. I did change the oil at 20hrs. When i started this season, all i did was put in fresh fuel,lubed the zerks on the fron wheel axles, and checked the air in all the tires. I am using a set of gator blades and they are ready to be sharpened. I will get another set for a spare. Then use the stock blades again in the heat of the summer slow growth period. Should i take apart any of the pullies, do they need lubing? Not sure if they run on percision bearings?? Is there anything else i should do? I dont care for the local dealer which is about 30 miles away. So i like to do the maintence myself if its not a big deal. So far, i have not had 1 single problem, except the auto shut-off seat sensor was bad when i got it. I have been so happy with this machine. Thank you Hustler for such a awesome ride! Thanks for any advise.
