Congrats! I have the
L3901...same tractor, more HP. You will love it. Couple thoughts:
-Your rears may already be widened from what it looks like in the pic, but if not and as was already said, huge difference in stability so I would widen if needed
-Get some bucket hooks
-Consider adding mats to the floor deck before you give it much use. It will not only protect from wear, but it also makes for a better gripping surface. Low cost do-it-yourself with a rubber stall mat and bolts.
-As was said, get the right fender handle, especially if planning to use rear implements. This overpriced part is well worth it.
-You may find the seat cut off switch to be annoying; one low cost zip tie later and frustration gone....(You may hear from the safety police on this one)
-Run at higher RPMS as recommended to reduce the frequency of regens. Seems counter intuitive, but the engine is designed to run this way for a reason
-I could certainly help you spend more of your money with additional ideas, but the last tip is to just enjoy your new machine!!
