I bought a used 2008 T4030 in 2010. I am possibly in the market for a 3 point hitch firewood processor but want to make sure that it has enough hydraulics to handle it. Specs say that it either comes with a 12.8 gpm or an optional 16.1. How can I tell which one? Called the NH dealer and they weren't sure. It came with two remotes, so I am hopeful for the bigger pump. The smaller pump is 0.8 more than the least recommended by Wallenstein but I would rather be in the middle to upper end of the specs if possible. Thanks.
The GPM's can be determined by warming up the engine.
Plug a hose into one of the remote outlets and place the other end in a 5 Gal bucket.
Rev the engine to max, and then push the remote lever to max for the work port with hose..
A 12 GPM pump will pump 12 GPM in 60 sec
