The long ones also serve as a rake. I have an artillian grapple with decent bottom tines because it's also a considered a root rake. Having long tines allows you to scrape the ground in order to clear it, plus you can take up small stumps with them. I have never used short tines but I would think that set up might make it a little easier to pick up logs while you are over the top of them. At the end of the day, if you have no need to rake the ground or get up roots/stumps then its a preference type of deal is my opinion.I noticed that some of the EA models have short tines on the bottom, some long ones. What are the benefits and/or drawbacks of each? I hope to be purchasing one of the not too distant future, and I’m trying to narrow down to my final decision. Thanks in advance.
