I've used this Caroni finish mower for about a year now and have been quite pleased with it. The mower gives a nice, even cut -- better than my Troy Built garden tractor, in fact. I generally operate it at a ground speed of 5mph, but do have to slow down when cutting tall grass otherwise the discharge chute tends to clog.
Just after starting this season's mowing, I replaced the belts and blades on the Caroni finish mower. The parts cost about $50 for two new belts and three new blades which seemed pretty reasonable. It took about two hours for me to do the maintenance, but that will be a lot quicker next time now that I'm familiar with the process.
Routine maintenance for the Caroni finish mower is relatively simple. After each use, you should clean the grass and debris from the top of the mower. Then, look under the mower and remove any wire, rope, etc that may have gotten wrapped around the blades. Also, check the blades for damage -- especially if you mow an area where there are rocks or other hard objects around. After every few hours, grease the blades and wheels with a standard grease gun and adjust the belt tension. Once a season, or more often as required, sharpen or replace the blades and inspect the belts for wear.
