It pays to pay attention to proper bolt torquing

Understanding the logic of bolt strain will help you realize the importance of double-checking the torque values, especially on those short bolts that are often used on many vehicle and farm equipment wheels

by RALPH WINFIELD

When I started working in the local repair garage in the 1950s, torquing wheel studs and head bolts was something you did by a guesstimated equal pull on a breaker bar. Breaker bar was (is) still a common term for a half-inch drive-socket holding bar with a swivel head, an integral part of every toolbox contents.

New ideas for more accurate and efficient tillage

A major European implement maker, who puts the emphasis on cost control without quality penalties, is targeting North American markets

Anyone who has followed the world plowing championships over the years won’t need to be told about Lemken, the European master plow-maker producing the light blue implements that have won this award many times. Based in north Germany, the family firm has been making plows for over 230 years now – ever since Wilhelmus Lemken first fired up his blacksmith’s forge there in 1780.

Can a six-legged ‘spider’ tractor handle tricky transport tasks?

The Mantis stands 2.6 metres tall to the top of its cab with five metres between opposing ‘feet’

by NORMAN DUNN

A prototype “spider” tractor developed in Britain claims to reduce crop or ground cover damage during difficult transport jobs – or offer a unique cross-country transport for tourists. The so-called Mantis Hexapod from Micromagic Systems achieves this by avoiding wheelings altogether and relying on its six hydraulically powered legs to overcome demanding surfaces and obstacles.

Interest in tracked tractors grows across North America

So say the equipment manufacturers, citing better traction and compaction resistance. But tracks are more expensive than tires, and others are less certain about the overall benefits

by DON STONEMAN & MATT McINTOSH

Jean-Luc Jaquemet has been thinking about getting a tracked tractor for about 10 years. This spring, his opportunity came and he put his money on a 525-h.p. Challenger 865.
