I'll refrain from commenting on price b/c I'm a dealer too, other than to say that some dealerships (like mine) order the 41hp R models with an upgrade to the larger wheels and tires that are standard on the 47hp units..... that bumps the price up about $400 over the std configuration
but I will comment on the models:
The R4010 & R4010H have been replaced with the R4041, R4041H, and also the new R4041 EZ-shift
The R4047 is the replacement for last year's R4020, and it also comes with the same 3 tranny options.
compared to last years models, you're getting the new body panels, a fender mounted joystick control for the loader, and telescoping lift arms on the new 4041 & 4047.... they're a little higher priced too. All the major components are the same, as are the machines' capabilities, IMO.
