Bingo! "If it's just a matter of having a multi use tractor vs a single use forklift, I understand that too."Sounds like you've answered enough questions to know that the LX2610 and the L2501 will lift what you need to do easily. Filled tires should be enough ballast for 650 lb loads. I've lifted/carried way more than that with only filled tires and no additional ballast on not so flat gravel driveway. No pucker factor.
Just don't buy forks that weigh 500lbs.
In reading your original post my question would be related to your statement "I love the idea of the versatility". What did you have in mind here? Are there other specific things you plan on using it for? If so, those specifics might help make your decision. If it's just a matter of having a multi use tractor vs a single use forklift, I understand that too.
We have uses for a tractor other than just pallet work.
Thanks for your input.
