That's not a bad price at all, especially if dealing with the used oil is an issue, like it is for me.
I believe you have three belts: transmission, deck, and PTO. Considering most of them are the kevlar type, that price seems about on par with anyone else.
sharpen blades and balance $50.00
Blade sharpening should be about $5-$8 per blade. If you don't have the ability to remove the blades from the deck, then you're kind of at the mercy of the dealer on this one. If that $50 includes the labor to remove the blades from the deck, then I can see why he's charging that. It's expensive though, might want to consider getting an air compressor and an impact driver to do this yourself. Will take about 6 years to pay for itself just in blade removal/installation costs.
Seems about right.
Also seems about average, though you could possibly save up to $40 or so if you shop around.
Don't know how far you are from your dealer, but I'm about 16 miles and that's about what my dealer would charge me.
3 hrs @ $55.00/hr $165.00 labor could be 2 to 3 hours
Wow, I wish we had rates that low around here. We are in the $70's and $80's here.
Seems about right too.
The thing you should consider is that the 149 isn't going to be any less maintenance prone to what you have now. It'll last longer in the end, but it'll still require work. If the work listed above is not things you are comfortable doing yourself, or don't have the tools to do yourself, then the 149 isn't going to save you any money year-to-year. What it will probably save you from having to do though is buy a new tractor in 5-10 years, depending on how your 1018 holds up.
But, if you're looking to get into doing these tasks yourself, then the 149 is a good tractor to start with. It's rugged, simple, and will give you some exposure to hydraulics. Plus parts are still readily available.
