Rotorua Trails Trust chairman Gregg Brown said it would totally change the way the trust dealt with trail maintenance and building.
The trust builds and maintains forest trails for mountain bikers, runners, walkers and horse riders.
"It's hard to judge right now, but we imagine it would at least halve our trail-building costs. We think that every hour on the digger will save about four man-hours on a shovel.
"It's a game changer for us, we are just stoked and very happy with what Ray and Paul have done."
He said trail maintenance was a huge part of keeping the forest trails at a high level in terms of safety and quality for all users.
