Vendors and Part Numbers (See Rear of Manual) SAFETY -PRECAUTIONS The Trojan Tractor Shovel has been designed to incorporate every safety device possible. The Trojan ((Safety Curve Lift Arms*" which has been widely imitated but never equalled completely eliminates the shear hazard present in many other tractor shovels. Your Trojan has large, well-positioned steps with adequate hand holds so the ~perator can easily climb to the seat without having to step on a slippery tire. However, with all these safety features which have been incorpora;ted in the design of the Trojan Tractor Shovel there are still the dange~sQf rt.Jnnmg overa)~an. '~. dropping the bucket on him, etc. And therefore, thi}perator·m'ust:be~1{tremelycarefulin the operation of a big tool such .~s this.
