They usually raise funds on route for Ronald McDonald House, and this time they've come together with other members of the David Brown Club NZ.
"We came up north because one of our members lives in Kerikeri," said one of the tractor drivers, Trish Short, from Te Awamutu.
"We went right up the top to Cape Reinga, we knocked the bastard off."
Tractors proved a sensible mode of transport during the wet Northland weather they encountered.
"Oh my goodness gracious me, we certainly saw some weather," Ms Short said.
Even driving tractors, the trekkers were advised to leave out the leg along Ripiro Beach between Dargaville and Pouto Point.
Following the region's recent weather that beach would be sandscaped with cut-outs, debris, soft spots and high water.
Instead the group changed its plans and ambled from Whangarei to a camping ground at Waipu Cove yesterday, at a cracking pace of around 20km/h.
They expected to have the chat last night about how to tackle Auckland - the city is a problem there's just no way around.
"It's a major because we're not allowed on the motorways, we're too slow," Ms Short said.
"Being as we're country people, we can get a bit lost. On the way up here nine of us ended going down the wrong suburban road. But tractors are pretty good at turning, we can get out of a tight spot."
As for other motorists: "We've done an awful lot of driving on roads in our tractors and we know about being courteous, but, boy, are there some idiots out there!"
