New Length Options

25-ft Tunnels are Back!

Perfect for backyard growers, urban farmers, and market gardeners who are looking for a space efficient propagation house or smaller growing space, the new 25-ft Caterpillar Tunnel is everything you love about easy to build caterpillar tunnels all in a new convenient size!

All 25-ft tunnels now come with 55-ft of greenhouse plastic (up from 32-ft) so you have plenty of extra plastic for the standard cone-shaped ends, or to use in alternate end wall coverings.

Year-Round Crop Protection

Caterpillar Tunnels are often viewed pri­mar­i­ly as a sea­son exten­sion tool, but that’s real­ly only half of the sto­ry. Covered grow­ing space pro­vides year-round pro­tec­tion for your plants from things like rain, pests, frost, heat (when using shade cloth), wind, and even from dirt being splashed onto your plants in heavy down­pours.

This is my fourth tunnel from Farmers Friend and every one has been well worth the price. Having everything come at once and no trips to the hardware store is wonderful.

New Tunnel Options!

Wider, Stronger Tunnels Now Available!

Max out your farm with the thick­est gauge steel Caterpillar Tunnel on the mar­ket! We now offer a 16-ft wide tun­nel (up from 14 ft) with 40% thick­er, 14-gauge steel bows (up from 17 gauge).

With steel strength typ­i­cal­ly found only in com­mer­cial high tun­nels, these 14-gauge tun­nels are designed to give you greater peace of mind on stormy nights. Plus, being 2 feet wider, you’ll have plen­ty of room for 18-inch path­ways to more eas­i­ly trans­port har­vest bins/totes, or if desired, shrink your path­ways to 10 inch­es and fit five 30-inch grow­ing beds.

Gothic Tunnels

The Perfect Tunnel for Northern Growers!

Perfect for north­ern cli­mates with fre­quent snow­fall, the Gothic (pic­tured) will allow you to grow longer into the win­ter than a Classic Tunnel. This new tun­nel also includes a sol­id purlin and wind brac­ing to add even more rigid­i­ty to your structure.

For extreme win­ter grow­ing, upgrade to the Gothic Pro, which includes a Solid Purlin, Wind Bracing, Cross Bars and 16-inch Lift Kit for added strength and height.

5 out of 5 stars

Amazing Tunnel! Very pleased!!

I just want to say how happy I am with the Gothic Pro Tunnel we purchased. With the Pro package it has a lot of added support with the wind bracing and cross bracing. We had 50 mph winds yesterday during a storm and I’m so happy I went with the Pro package for the added support. Very pleased with the product! Definitely a game changer for our farm and is so enjoyable to have protected space to grow food in!

Our Classic Pro Caterpillar Tunnel includes a 16-inch Lift Kit for added height, plus Wind Bracing and a Solid Center Purlin for added strength and rigid­i­ty, as well as greater peace of mind.

Caterpillar Tunnel Options

Classic vs Gothic

The Classic tun­nel (LEFT) is cost-effec­tive and portable. It’s a great starter tun­nel and is excel­lent for those who fre­quent­ly move it around their farm or where wind is a greater problem than snow. The Gothic tun­nel (RIGHT) is an excel­lent choice for those liv­ing in north­ern cli­mates where snow is a fre­quent threat.

Versatility

Changing with the seasons.

Our Caterpillar Tunnels work great for start­ing crops ear­li­er in the spring, and keep­ing them going longer in the fall. In the heat of sum­mer you can eas­i­ly push the plas­tic all over to one side, or take it off com­plete­ly, and replace it with shade cloth to pro­tect your crops from the sum­mer heat.

We love our high tunnel!

We put our Gothic tunnel up last Spring, this was our first winter, and it has withstood snow, freezing rain, and high winds like a champ. We look forward to a second one, hopefully this Fall.

NRCS specifications

Our tun­nels meet the basic 325R National NRCS spec­i­fi­ca­tions. Ultimately, you should con­tact your local NRCS rep and pro­vide our instal­la­tion man­u­al found at the top of this page and the spec sheet(s) attached to our knowl­edge base arti­cle, “Do your tun­nels meet NRCS spec­i­fi­ca­tions?” for their review. Also, check out the NRCS guide below for step by step instruc­tions on how to apply!

NRCS Documents and Guides

Delivery

The Caterpillar tun­nels are shipped on a 4×8 wood­en pal­let via motor freight (an 18 wheel trac­tor trail­er). Depending on the order, some­times mul­ti­ple tun­nels can fit on one pallet.

You will receive a pro num­ber for track­ing from Farmers Friend when your ship­ment is picked up from our facil­i­ty. It is rec­om­mend­ed that you con­tact the car­ri­er pri­or to deliv­ery to make arrange­ments for time and date. There is some flex­i­bil­i­ty in date and time of deliv­ery, but cus­tomers in remote areas should accept deliv­ery at the car­ri­ers con­ve­nience to avoid exces­sive delays or extra charges.

Unloading

Prior to mov­ing or unload­ing, please take pic­tures of the order. This is in case items are miss­ing or dam­aged we have a way to ver­i­fy con­tents and con­di­tion. We rec­om­mend con­duct­ing an inven­to­ry of the ship­ment with your includ­ed pack­ing list as soon as pos­si­ble after unloading.

As far as unload­ing, it is the cus­tomer’s respon­si­bil­i­ty. The car­ri­er will not have a fork­lift to unload. A fork­lift or trac­tor with forks is not required, as the ship­ment can be unloaded by hand with two peo­ple. Simply break the bands and remove the pack­ag­ing. The indi­vid­u­als unload­ing should be capa­ble of team-lift­ing 130 pounds. Out of con­sid­er­a­tion for the car­ri­er, we request you pre­pare to unload as quick­ly as possible.

Farmers Friend will not autho­rize the use of any lift­gate ser­vices, and they are not includ­ed in any ship­ping charges, nor is it includ­ed with free ship­ping. If the local ter­mi­nal or dri­ver offers lift gate ser­vices, do not accept them for any rea­son as there will be an addi­tion­al charge billed to you from Farmers Friend at $150.

Wind Rating

There is no offi­cial wind rat­ing on our tun­nels. The cater­pil­lar tun­nel is designed to be a move­able struc­ture. Therefore, it is inher­ent­ly not made to with­stand high winds.

A tun­nels abil­i­ty to with­stand wind is based on at least 6 factors:

  1. Soil type
  2. Water Saturation
  3. Bracing
  4. Anchoring Selection
  5. Wind Direction
  6. Customer Installation

Soft soils have less grip on the anchor­ing mate­ri­als, while more com­pact soils hold better.

Related to soil type is ground sat­u­ra­tion. How wet is the soil at the time of said wind event? Saturated soil will be more like­ly to let go of the anchors.

The stan­dard cater­pil­lar tun­nel is sta­bi­lized by a nylon purlin strap. Accessories that increase rigid­i­ty while main­tain­ing the cater­pil­lar attribute of move­able are: Solid Center Purlin, Wind Bracing, and Spring Wire.

Anchoring options that exist for cater­pil­lar tun­nels are rebar, cement­ed ground posts, and Earth Anchors. Rebar is the most eco­nom­i­cal indus­try stan­dard effec­tive in mod­er­ate winds. Cemented ground posts elim­i­nates the Caterpillar Tunnel strength of tem­po­rary, but pro­vides a rock sol­id foun­da­tion. Earth Anchors are an expen­sive ground screw option that holds like con­crete but is eas­i­ly removed and reused.

Tunnels have also been report­ed as hav­ing prob­lems with the plas­tic being blown to one side from broad­side winds. Spring wire is a solu­tion to aid in pre­vent­ing this occurrence.

Customer instal­la­tion is the final fac­tor. Assuming all instruc­tions are fol­lowed and instal­la­tion is cor­rect, the stan­dard tun­nel can with­stand light winds and mod­er­ate gusts.

With all that said, our stan­dard tun­nels have with­stood winds up to 50+ miles per hour. In the cas­es where sim­i­lar winds have dam­aged tun­nels, the six fac­tors must be analyzed.

The pru­dent grow­er would do well to eval­u­ate these six fac­tors in light of their bud­get, short and long-term farm plan, and spe­cif­ic grow­ing context.

Rose P.over 1 year agoVerified buyer

It arrived the day before Thanksgiving. Wanted to push out our Thanksgiving guests the next day so we could set it up! My husband did all the metal parts the day after thanksgiving and we got the plastic on the next day. Nice and sturdy and has made it through some very high winds already! Word of caution, if you don’t want a comedy show for your neighbors, put the plastic on a day where there is no wind🤣

Yes, I am satisfied with the professional interactions with the staff, the price of the Hi Tunnel Gothic structure, and the delivery of the new Hi Tunnel. It arrived sooner than estimated in good condition packed securely in plastic wrappings on a palette as described. I hope that everything goes as well when it is assembled.

Fairly easy to install, just need a day with little too no wind to put up the plastic. Haven't grown in it yet but putting it together was fairly easy, extra parts were useful. I'm happy with the purchase and would recommend.
