Telstar2112,
A few comments:
1. The operator's manual for the
L3130 states the maxium rotary cutter size is 72" and 770 lbs
2. Do you have a need for mid PTO, such as for front mounted snow blower usage or mid mower? If so, you might want to check if the
B21 and
L35 are capable of a mid PTO operation?
3. Might also want to check if the FEL is removable on the
B21 and
L35... Assuming this capability is important to you.
4. The
L3130 didn't come standard with mid PTO, but it can be added very easily. (This doesn't hold true for all L series and there are a few specific models where it is significantly more difficult and expensive)
5. Quick Attach bucket is well worth having even if you don't have an immediate need for it. (Quick Attach is for removing the bucket from the FEL arms. This makes it easy to swap between bucket and pallet forks for example.
6. Don't underestimate the cost of 3-pt arms if they are missing. They might be available as whole goods cheaper than buying the individual pieces through parts.
Good luck searching for your tractor!
