How wide an R/C?
What is the lift capacity of your Three Point Hitch?
Do you have an FEL or weights on the front of your L4760?
Do you want to mow sloping land, or just flat land?
What diameter stuff will you be cutting? Hardwood or softwood?
What is the max amount of money you can spend?
Almost, almost all R/Cs sold new today have gearboxes, shafts and blades from just two suppliers in China. These suppliers sell multiple grades for multiple price points. A zillion of these components can be packed in one shipping container from China to Long Beach, California or Mobile, Alabama, then on to implement manufacturers in the South.
This includes my Land Pride RCF 2060 @ $1,600 without sales tax, purchased January 2014.
