Hi,
I'm presently being offered either a GXD21 with 900+ hours on it, or a GZD15 with only 150 hours on it...for the same money. Both are about the same age. The GZD21 seems a little expensive given its hours, whereas the GZD15 seems a reasonable price.
Which do I choose? I'm aware that both are near identical except the GZD21 has increased power from a 20hp 3 cylinder engine, rather than GZD15 has a 15hp 2 cylinder engine. Other than that the only differences are collector size (500L versus 400L) and cutting width (3 blade 48inch rather than 2 blade 42inch).
Thoughts and advice? I'm aware the 3cyl in smoother and should last a long time (as I suspect its the same as what they put in their micro diggers etc), but the 2cyl I think only goes into their mowers, and by virtue of dropping a cylinder will be a little rougher running.
Cheers,
Oly
