TransPro™ 648 Tow-Behind Trailer

ProCore® 648 or 648s Aerator

Model No. 09964-Serial No. 323000000 and Up

Safety

  • This trailer is intended for use with ProCore 648 and 648s machines only. Towing incompatible products can result in damage to the trailer and/or injury to the operator and bystanders. Refer to Compatible Machines for a complete list of compatible machines.

  • Use only a vehicle with the proper tow rating; the TransPro 648 trailer and a ProCore aerator with attachments has an approximate combined weight of 1089 kg (2,400 lb). Ensure that the tow vehicle has adequate braking and handling capacity by checking the recommendations of the vehicle manufacturer.

  • Ensure that the trailer is properly connected to the tow vehicle before loading or unloading the aerator to prevent sudden unintended tongue movement or flip-up. The trailer tongue should be parallel to the ground when you align it with the tow vehicle hitch.

  • The trailer adds extra towing weight to the vehicle. Drive the vehicle safely.

    • Do not drive the machine on highways or public roads.

    • Always slow the tow vehicle when approaching and while making a turn.

    • Always slow the tow vehicle when driving in unfamiliar areas or over rough terrain.

    • Always slow the tow vehicle when changing the direction of travel or preparing to stop.

    • Always slow the tow vehicle when turning or driving on slopes.

    • Do not make sudden or sharp turns. Do not suddenly change direction of travel on an incline, ramp, grade, slope, or similar surface.

    • The maximum towing speed is 15 mph (24 km/h). Always adjust the tow-vehicle speed to allow for existing ground conditions, such as wet slick surfaces, loose sand or gravel and/or low visibility conditions, such as dim or bright lighting, fog, mist, or rain.

    • Be especially careful when driving a heavily loaded vehicle down an incline or slope. Drive the vehicle up and down the face of the slopes, inclines, or grades whenever possible. Do not drive across the face of a slope if at all possible. There is a risk of upsetting the vehicle, which can result in serious injury or death.

  • Do not operate the tow vehicle or use the trailer when tired, ill, or under the influence of alcohol or drugs.

  • Use the trailer only in good visibility and appropriate weather conditions. Do not operate the tow vehicle or use the trailer when there is the risk of lightning.

  • Before backing up, look behind you and ensure that it is clear of people and objects. Back up slowly and watch the trailer movement closely.

  • Use extreme caution and slow speed when backing up the trailer and tow vehicle.

  • Watch out for traffic when near or crossing roads. Always yield the right of way to pedestrians and other vehicles.

  • If the trailer begins to vibrate abnormally, stop the tow vehicle immediately. Shut off the tow-vehicle engine. Repair all damage before towing.

  • Before servicing or making any adjustments to the trailer, do the following:

    • Stop the tow vehicle and engage the parking brake.

    • Shut off the tow-vehicle engine and remove the key.

  • While the trailer is disconnected from tow vehicle:

    • Store the trailer on level ground.

    • Chock the wheels to prevent the trailer from moving.

  • Keep all fasteners tightened securely. Replace any parts removed when servicing or making adjustments.

    Note: When storing the trailer, you can push the hitch tube back into the trailer frame tube to shorten the overall length.

Loading the Trailer

Warning

Stepping on the ramp may lead to loss of footing.

Walk on the ground while guiding the machine up or down the ramp.

Preparing to Load the Trailer

  1. Connect the trailer to your traction unit; refer to your traction unit Operator’s Manual.

    Important: Ensure that the trailer tongue is parallel to the ground when it is aligned with the tow vehicle hitch; if it is not, refer to Adjusting the Trailer Tongue.

  2. Remove the pins from the top of the ramp and wheel plate to lower the ramps.

  3. Install the pins to the front of the wheel plates.

Loading a Machine on the Trailer

  1. Remove the storage pins from the top of the ramp and wheel plate to lower the ramps.

  2. Install the pins to the front of the wheel plates.

  3. Park the trailer on a level surface and move the line marker on the machine to the storage position; refer to your machine Operator’s Manual.

  4. Walk on the ground while slowly guiding the machine up the ramp and onto the trailer until the front wheel rolls over the integrated chock and rests against the front trailer guard (Figure 5).
