I'm fixing to upgrade my ride on mower. I have used an la100 for 7 years now, yup SEVEN. It still has at least a couple more years left on it but the deck is now finally done when it comes to mowing grades more than 15° I'm have clients that there yards demand a certain finish even though they are on a 20° grade or more in some places. How they talked these people into buying these homes is beyond me. But up until just recently I hooked my scalping wheels and it pulled off. I could weld it back on, but I know I'm over 500 hours on my la100 and I looking at an X300 I have read many post on D130 vs. x300. But none of them cover a couple points. Fuel usage, Weight, and how fixable it is for a journeyman. I know where everything is on my la100 and I can fix anything on it except an engine rebuild. This saves me big time when you can do it yourself, when your a solo like me. Is that deck and spindles going last longer than the D130? I have replaced my spindles on la100 once since I have owned it; the deck- I have had to weld it once but nothing major. so, I figure Id post this before I bought one. the x300 come with a 38,42,48 and I can only have a 42 because of gates. but the 42 doesn thave 4 wheels on the deck =-( only 48 and larger.
