For 10 years, Nigel Curtis has put up with the motorbikes tearing through the neighbouring property at all hours of the day or night.
But Monday 'the last straw' fell for the Euberta farmer.
He approached the riders, requesting that they leave. That's when the death threats began.
"They drove their ute onto my land," Mr Curtis said.
"They made threats against me and my family, saying they would turn their chainsaws on us. They even started up their chainsaws too, as a threat."
Mr Curtis' property on Old Narrandera Road is bordered by Crown land, and for the past several years he has leased the grounds as a grazing site for his cattle.
"It's about 160 acres over there, and I'd say about 80 acres of it is all torn up by motorcycles," he said.
Mr Curtis said his investigations showed the motorcycles that frequented were unregistered, and therefore illegally ridden on the land.
"They've left little for my cattle to feed on, and they've even chased them when they're there," he said.
"I've had enough, I'm at my wits' end. We are in the worst drought we've seen in 50 years, we need that land, it's a prime stock reserve."
Over the years, the riders have been issued with fines for the use of unregistered motorcycles.
It is a fine that carries a penalty of up to $1899 in NSW.
But Mr Curtis said he has pleaded with police to also confiscate the offending motorcycles, to stop them from causing further damage to the grounds.
Mr Curtis' property is surrounded on one side by the Murrumbidgee River and bordered the other by the Crown land.
In the past, he said, following a visit from the motorcyclists, Mr Curtis has had to call the local fire department to extinguish spot fires spreading onto his land.
"I don't know if they're deliberately lit, I think they probably are," he said.
"It's all not good for the land, and it's not good for the cattle."
With the pressures of the drought surrounding the family farm, Mr Curtis said he is consistently confronted by starved and dying cows on his property.
He is also concerned that the stress of the noise and instances of being chased by the motorcycles, has contributed to the untimely death of his livestock.
"We have no-one else to turn to, we desperately need help to stop these people riding their bikes on local reserves. We pay good money to lease [the land] to feed our livestock," Mr Curtis said.
